Storylines[]
Jonno is first seen after being contacted by his son Callum Highway's fiancé, Whitney Dean. He has a disagreement with Ben Mitchell over gay pride and is confronted by his father, Phil Mitchell. It is revealed that Jonno was not a good father to Callum or Stuart and would be violent towards Stuart. He reveals that he has changed and attempts to reconcile with his family. Jonno confronts Ben in the toilets and expresses his disgust with homosexuals, causing a fight between him and Ben. Jonno's true colours are exposed when he pins Callum up against a wall and verbally assaults him. Stuart threatens him out of Walford and he leaves. Jonno returns two months later, wanting to find out how Callum's wedding went. When he discovers that the wedding was called off he confronts Callum about it, and Callum comes out as gay to his father. Disgusted, Jonno accuses Ben of turning him into "one of them", earning himself a punch from Phil in return. After claiming that he will go the police to report an assault, the punters, including Whitney, all suggest they would deny all knowledge of Phil attacking Jonno. Annoyed, he leaves, disowning Callum in the process.
Jonno returns in September 2025 and is seen beating up Eve Unwin in a homophobic attack. When Callum approaches him, Jonno states that he's visiting the area, and believed that Callum moved away. After being urged on by Eve, Callum arrests Jonno and later disowns him. Johnny approaches him claiming to assist him as a lawyer, but after Jonno gets suspicious, Johnny reveals he is Mick Carter's son. They later have a drink together in the Queen Vic, where Jonno claims he was not being homophobic, and that he loves his son regardless of his sexuality. Callum arranges for Jonno to come over to his apartment to talk. The conversation starts off civil and polite, but quickly turns more heated as Jonno demands money from Callum. Due to the stress of the argument, Jonno has a heart attack. Johnny calls an ambulance whilst Callum tries to find Anthony Trueman, a doctor. Unbeknownst to Callum, Jonno's last words mentioned that Callum is a disgrace, however Johnny lies and says that his lasts words were that he was proud of him.
