Adam's introduction to the show begins when Manda Best tells her boyfriend Minty Peterson that her son, Adam is on a summer holiday abroad but will return to the UK shortly due to his academic studies. Minty is reluctant when Manda suggests Adam stay with them as they don't have a spare room as they have a lodger Darren Miller (Charlie G. Hawkins). However, Manda makes arrangements for Adam to stay and he arrives on 10 September 2009. He quickly forms a low opinion of Minty, and takes a liking to Libby Fox, Darren's girlfriend. Libby is due to go to Oxford University, so they become friends. He returns to Oxford at the end of the summer holidays, texting Libby that he will see her there.
Adam returns to Walford unexpectedly and continues to be rude and hostile to Minty. He is also shocked to discover that Libby and Darren are engaged. He soon returns to Oxford but his car breaks down whilst he is in hospital for a routine health check. Not wanting to worry Manda, Adam phones Minty for assistance and Minty goes but confronts Adam about his rudeness. Adam tells Minty that he is very wary of his mother's usual choice of men, as many have let her down in the past. However, he agrees to try to be more polite in future.
He returns over Christmas and wonders why Libby is with Darren, thinking she cannot see beyond his wheelchair. Following the revelation that Darren is the father of Heather Trott's baby son, Adam teases Darren about Libby. He defends his mother when Minty is angry at her for not telling him about Darren and Heather. He continues to tease a distraught Darren after he spent the night on a bench, but Manda tells Adam he should know when someone is in need. Adam then takes Darren to a party and agrees to look after him. The next day, Darren wonders what he should say to Libby, who has gone back to Oxford early. Adam tells him he should give her some space, and Darren agrees, but Adam then sends Libby a text message saying he is there for her if she needs a friend.
When Manda comes home one night in tears, she tells Adam she thinks Minty is having an affair. Adam and Libby search for evidence and find a letter that Sam Mitchell has sent him. Adam decides not to tell his mother but Libby says they should and she tells Manda about it. Manda decides to leave Walford after Minty admits having feelings for Sam. Adam returns to Oxford and when he comes back to Walford again, he and Libby are dating. Darren confronts him saying he has probably been bad-mouthing him for months, and Adam hits back by saying that Libby makes up for being unattractive by being good in bed. Adam spots Libby in the cafe where Fatboy starts to flirt with her and after Libby leaves, Adam punches Fatboy.
Adam is approached by Lucy Beale for help with her exams. She pays him for exam papers, but after Adam is annoyed by Libby's behaviour during a picnic, he tells Lucy he wants payment in kind, not money and demands a kiss as a down payment. Minty sees them kiss again but Adam tells him that Lucy is very tactile. After Lucy's final exam, Adam demands sex but she refuses, saying she has played him at his own game and won. Adam threatens to expose Lucy's tricks but Lucy says that anything would be better than having sex with him. Lucy tells her brother Peter Beale that she was blackmailed by Adam, who confronts him and threatens to tell Libby. Adam says that it would not be a good idea as Libby is still coming to terms with the deaths of her parents Denise Wicks and Owen Turner (Denise is later found alive). However, Libby is standing behind him and hears everything, then reveals it to a crowd that gathers after throwing his belongings out on the street. He accuses her of only dating him to make herself look good and says she will be trying to kill him next. He insults Denise, so Libby slaps him and tells him to leave. Adam gets in his car and drives away.
