Louise is the daughter of Phil Mitchell and Lisa Fowler. Lisa and Phil had a violent, turbulent relationship. After Lisa ended her relationship with Phil and moved in with Mark, it is revealed she is pregnant. However, she keeps this secret as Phil keeps belittling her in public. On Mel Owen and Steve Owen's wedding night, Phil says that he never loved her and suggests that Mel gives her tips in the bedroom. In revenge, Lisa steals a gun from the e20 nightclub and shoots Phil. He survives and confronts her after leaving hospital but realises that he drove her to it and frames his enemy Dan Sullivan instead.
Wanting to keep Phil away from her child, Lisa and Mark Fowler marry, claiming that he is the baby's father. Everyone believes it and their romance becomes real. Lisa gives birth to baby Louise, and Lisa tells Sharon Watts, that Phil is Louise's father. Sharon, however, tells Phil that Louise is his daughter and he forces them to accept he will be part of Louise's life. He dumps Sharon and demands Lisa to change Louise's name to Louise Mitchell, which she does. Louise is taken by Steve Owen (Martin Kemp) as he drives to the airport to leave Walford, but Phil chases after Steve, who crashes his car. Phil manages to rescue Louise and goes back for Steve, but the car explodes into flames, killing Steve. Despite initial animosity, when Lisa sees Phil with Louise, old feelings resurface and they eventually reconcile. However, Phil wants Louise, not Lisa, and when she realises, she is kicked out by Phil and Peggy Mitchell. They take over caring for Louise, excluding Lisa and hiring a nanny, Joanne Ryan telling her that Lisa is mentally unstable. This comes to a head on the day Peggy throws a party to celebrate changing Louise's name to Mitchell. Desperate to get away, Lisa and Louise go to Portugal, joining her best friend Mel Owen. When Phil finds a postcard with Mel's address, he goes after her; returning with Louise and tells his family that Lisa will not be back. The police are suspicious and send undercover officer, Kate Morton, trying to get Phil to confess to Lisa's murder. Kate gets a confession but it is not what she and her boss expect; he bullied Lisa to give him custody of Louise and told her to stay away so Louise would not be confused. Phil goes on to marry Kate, and is shocked when Lisa returns on their wedding day, wanting Louise back. Lisa plans to shoot Phil again, but Den Watts talks her out of it and looks after her. He and his son, Dennis Rickman frame Phil for armed robbery; when he is arrested, Lisa takes Louise and leaves Walford.

Wanting better for Louise, she calls Social Services, who take her into care. However, Phil finds out that Louise visited and angrily confronts Ronnie, just as Louise enters The Queen Vic. Louise spends the weekend with her father and he tries to keep her visit a secret. When the police arrive, he tells them he has not seen her. Phil allows her to stay off school, annoying Ben. After Phil speaks to Shirley Carter, he decides to contact Social Services, who take Louise away but Phil vows to fight for custody. However, he soon learns that he will need a DNA test to prove he is Louise's father as Mark is listed as Louise's father on her birth certificate.

Phil forces Louise to apologise but she does not, and when Phil is out, Ben burns Louise's hand with a hot spoon. Louise sees Ben with alcohol that he took from the pub and tries to get Ben in trouble by asking Phil what alcohol tastes like. Later, Ben tells Louise that Phil will not believe her if she says anything but if she does, he will make her pay for it. Ben is asked to take Louise to school but locks her in a shed all day, making Phil think she has run away because he saw a note she wrote saying she wishes she was not there. Ben "finds" Louise and takes her home and she blames Jordan Johnson for locking her up. Ben tells her she is a good girl and will not lock her in the shed again. The next day, Phil sees burns on her arm and she blames Ben. A suspicious Phil questions Ben but he denies burning Louise and locking her in the shed. Phil asks Heather Trott to keep an eye on them but Ben sends Heather out for some crisps and a DVD. Worried, Phil rushes home and sees Louise's doll in pieces and Ben about to burn his sister. Ben claims he is playing a game but Phil angrily punches him. Ben is later imprisoned for attacking Jordan.
Phil learns that Lisa has applied for contact but he keeps this from her, asking Ritchie Scott to find a legal way of stopping Lisa seeing Louise. Louise asks Peggy when Lisa is returning from her holiday. Peggy reveals that she already has and that she wants to see Louise. Louise demands to see her mother, but Peggy insults her, so Louise storms off and then runs away. Phil eventually finds her and she tells him she wants to see her mother and needs to know if she still loves her but Phil shouts at Louise, telling her not to mention her mother again and she sees Phil slap Peggy when she says he is not fit to be a parent.

She is thrilled when she is reunited with Mel's son, Hunter Owen, whome she grew up with. Hunter leaps up from his chair and they embrace, calling her "maggot-brains" and Louise answering "the one and only." She is surprised, exclaiming that he doesn't look like his profile picture and he tells her that is because the photo is old and he grew up. Louise takes Hunter on a tour of Walford. They enter the cafe and Hunter explains that it isn't "how he pictured it". They sit down and order teas. Louise asks Hunter what his dad was like, he explains that he was an "old-school gent, and a looker an' all" and that he was a "sharp dresser." He goes on to say that his mum told him his dad was a "decent" man. Louise responds by saying she wished her father could be more like his. She asks if Hunter know how Steve died, in which Hunter says it was a heart-attack in his club. Louise apologises for his loss.
Later that evening, Ciara is enraged at finding out she doesn't have the full amount of money so marches down to find Mel and Hunter at the club. She, in retaliation, tells Hunter the truth about Steve's death, explaining that Mel has lied to him. She explains that his father wasn't the square's favourite man where "everyone dressed in their Sunday best" for his funeral. As she begins to explain Mel and Sharon come to both Hunter and Louise's defence telling them not to believe her and to go home. Louise refuses and Hunter demands to know the truth from Mel. Mel threatens Ciara, who laughs it off not believing she'll do anything to her. Ciara tells Hunter that his dad was "scum, a vicious thug", which Mel rebuffs in order to protect Hunter. Ciara tells Mel to be honest and Hunter asks Mel why Ciara would be saying this. Ciara then accuses Mel of not loving Steve and tells Hunter "Steve Owen was burnt alive in a car" and that he was trying to steal a baby at the time. Mel goes to hit Ciara but is stopped by her bodyguard. Ciara tells Mel that she is just "laying out the facts". Louise goes to Hunter to try to drag him away and Mel says that Ciara is lying. Ciara rebuffs this by telling Hunter that if he doesn't believe her, ask Sharon. Sharon stands her ground saying that "this has nothing to do with me", but Ciara tells her that she'll pay for ripping her off. Sharon tells her to "sing for it". Ciara tries defending her actions to Hunter, telling him that she wouldn't just tell him this to hurt him. Mel tells Hunter they need to leave, but he refuses. She tries to make Ciara look bad and that she is lying because of the money. Ciara denies this and then tells Hunter about Saskia Duncan - she was an old friend of Steve's and he killed her. He looks to Mel but she hangs her head in shame. Ciara then tells Hunter that he shouldn't be too hard on his mum because "what mother in their right mind would want their son to know their father was a murderer?"
Hunter and Mel go home and she explains to him the truth about what happened to Steve. He searches on his phone to look for facts about his father. Mel begins to explain that Saskia was an ex-girlfriend of Steve's who he got pregnant. She had an abortion, regretted it and attacked Steve over it. Steve fought back and ended up killing Saskia in self-defence. Hunter finds an article which says that "Matthew Rose, aged 18, was convicted of her manslaughter" and questions Mel over it. Mel explains that Steve framed him. He then finds an article on his dad's death which says that he died of "misadventure". He questions this and Mel tells him that there was a car chase, but she doesn't remember who was chasing him. He accuses her of lying again, but she denies it. He goes on to read that "a baby was rescued from the car" and asks who the baby was. Mel explains that it was Louise, and she would've only been about 18 months old at the time. He asks whether Louise knows about this to which Mel shakes her head. He asks why Louise was in the car, but she tells him that she'll tell him only when they are back in Portugal. He tells her that there is only one problem - he's not going back to Portugal, she can go be he won't. Mel later compares Hunter to Steve and asks for them to start again.
Later that week, after Hunter flirts with Louise, Keegan becomes jealous as he likes Louise a lot and he begins to look at pictures of Louise on her Facebook account. Louise invites Hunter to a lunch at her family's home which he accepts. Mel finds out and is against it, barging into the Mitchell home. Sharon and Phil invite her to stay and eat, which she accepts. Mel begins making jibes at a drunk Sharon, who responds by commenting on Mel's marriage to Ian Beale. Phil tells Sharon that that is enough, but she ignores him and goes on to go through Mel's failed relationships - like Billy. Mel says that she gets it, her and Hunter aren't welcome, and they get up to leave. Phil and Louise tell them not to, but Hunter says that he doesn't want to stick around to listen to Sharon. Phil tells Hunter to "sit down son", which Sharon questions - "son?". Mel turns to look at Phil, causing him to ask Sharon if she is alright, but she says she's fine - it's just a funny thing to call him. Billy and Honey Mitchell attempt to leave, but Sharon continues to ramble. She says that Hunter isn't Phil's son, "is he?", implying that Phil may be Hunter's father. Mel tells Hunter they are leaving, which he doesn't disagree with. Sharon then goes on to say that it's a strange thing to say, especially when Phil killed his father, Steve. Hunter storms out, with Phil trying to calm down the situation by calling after him, explaining that Sharon is drunk and she doesn't know what she's saying. Hunter gets upset and demands to know if what Sharon said is true, but Sharon and Phil argue that she didn't know what she was saying. Mel tries to drag Hunter out, but he pushes her away. He turns back to Phil and asks if it is true to which Phil says "it weren't like that." Mel tells him to shut up to which Hunter leaves, followed by Louise. Mel thanks Sharon, going on to explain that after 15 years she thought things would've changed. Sharon apologises, Mel rebuffs this saying that it's cheeky that Sharon would "have a pop" at her for "fluttering her eyelashes" when Sharon would go home with anyone who would by her a bag of crisps "back then." She then tells Sharon that she is the same as she always was - "a drunken, mouthy tart." Sharon then grabs a jug of cream and aims to pour it over Mel, but Mel grabs it and pushes her backwards, covering Sharon in cream. She then wishes Sharon a "happy Easter" before storming out. After Sharon has cleaned up, Phil applauds her. She yells at him to stop but he doesn't. Phil then puts the bins out, unaware that Hunter is watching him.
Louise and Hunter go to the E20 and Hunter makes Louise a coctail but they hide when Billy Mitchell and Jack Branning enter the room. Hunter then puts his hand up Louise's skirt but she stops him as she is not very confident about her scars. Later that day, Louise meets Hunter in E20 and he makes he feel confident again and tells Louise that "she doesn't know how beautiful she is". He then kisses her and Louise kisses him back, which leads to them loosing their verginity. Hunter uses the situation to his advantage and tells Phil to put security cameras in the club for protection and have them feed to his phone. Phil agrees to put security cameras in the club. On the night of the club opening, Hunter leads Louise into the office, they kiss and they have sex. Unaware to Louise, Hunter is making faces to the camera, as he knows Phil is watching. Afterwards, Louise notices the camera in the Mitchell home, Phil is watching on CCTV how the night is going; he notices Hunter leading Louise into the office and watches as they begin to strip and have sex. An angry Phil then grabs a baseball bat and marches down to the club to kill Hunter. He bursts in and shouts to Mel to tell her where Hunter is, unaware that he is hiding under the bar next to his mum. Mel denies all knowledge and says she's going to call the police, but Phil answers this by saying "they won't get here in time." Mel and Sharon follow Phil into the office and he explains that Hunter has raped Louise and it was captured on CCTV. Mel and Sharon are shocked at this and Mel leaves to find the teens. Phil shows Sharon the beginnings of the tape, where Hunter was making faces into the camera, and brands Hunter as "sick" as he meant for Phil to see it. Sharon tries to calm Phil down by telling him that Hunter probably didn't even know the camera was on. She tells Phil to delete the tape as Louise is 16 but Hunter is still 15 - meaning it is statutory rape in the eyes of the law. Mel texts Sharon to come outside as she has found Hunter and Louise. Hunter and Louise confirm that the sex was consensual, but Louise cries and says "the only thing I don't consent to is you all knowing my business." Hunter assures her that it is probably a misunderstanding. Mel asks Sharon how they can stop this from turning into a decade-long feud; Hunter asks if he has another decade in him. Sharon tells Mel that she'll take Hunter and Louise home, leaving Mel to try and calm Phil down. Mel tells Sharon "it isn't like you to leave me alone with Phil." Sharon answers her, smiling, by saying "you ain't no threat darling." Back in the office, Phil downloads the tapes onto his laptop. Mel comes in and Phil asks her where Hunter is. She explains that Hunter is at home and she has spoken to Louise; she likes Hunter and wasn't forced. Phil stands and tells Mel that if Hunter wants a war, he'll give him one. Mel stops him from leaving. Outside, Hunter asks Sharon if he can come over; Louise tells Sharon that "we weren't doing anything that you didn't do at our age." Sharon is offended by this comment and tells Louise to go inside. Louise kisses Hunter and leaves. Sharon confronts Hunter over the faces he was making to the camera, he lies and explains "I didn't know he was watching. I was just messing around." Sharon asks him how he think Louise would feel if she knew he was making faces at the camera; he says "she wouldn't like it." Sharon agrees and explains "what she gave you is so special." He says he knows, but Sharon questions if he really does. She tells him that she likes him, but "if I get a sniff of you disrespecting Louise again, I won't hold Phil back." Hunter says he understands. Sharon leaves. Back in the office, Mel calms Phil down and seduces him leading to them kissing. She then tells him to leave Hunter alone or she'll tell Sharon. Phil laughs it off, but Mel points to the security camera saying that she'll show Sharon. At this point Sharon and Jack arrive outside the club and see Hunter; they ask what he is still doing out, he explains that he was worried about Mel - "she's been in there ages." Sharon and Jack walk into the club and check if everything is alright - Mel confirms it is.
