[...] Alfie starts getting hallucinations and one in particular is quite harrowing."
Roxy Mitchell
Roxy is comforted by her friend and boss, Alfie Moon (Shane Richie), after her attempts to seduce Max Branning (Jake Wood) are made public. Realising she has feelings for Alfie, she confesses she loves him. Although Alfie admits to being tempted, he remains faithful to his wife Kat, who is away visiting family. Roxy and Alfie remain friends and colleagues despite Roxy's growing affection for him. After Alfie goes to visit Kat, Roxy becomes concerned for Jean Slater's (Gillian Wright) welfare and asks Alfie to return home. He returns with Kat, who throws Roxy out. Seeing that Alfie is in financial difficulty, Roxy gives him a loan from Amy's Child Trust Fund. Suspicious of Roxy and Alfie's friendship, Kat confronts Roxy and she admits she had a crush on Alfie. Kat sacks her from the pub and she moves back in with Phil. Phil once again takes control of the Queen Vic kicking Kat and Alfie out due to unpaid rent. He then appoints cousin Roxy as manager once again running it alongside Alfie and Kat. Roxy has brief flings with AJ Ahmed (Phaldut Sharma) and Michael, who she moves in with for a short time. When Alfie and Kat split up, Alfie asks Roxy to live with him and they declare their love for each other. Roxy is delighted when Alfie decides to divorce Kat, though it leads to more hostility between Kat and Roxy, which leads to a physical fight.
