List of Kat &amp; Alfie: Redwater characters
Alfie Moon is played by Shane Richie. The character originally appeared in the soap opera "EastEnders" from 2002 to 2005, and 2010 to 2016. Before his departure from "EastEnders", he discovers he has a mass on his brain. Of Alfie's part in "Redwater", Richie said, "Alfie's journey is to help his wife find her son but at the same time he has his own dark secret which he's keeping." Richie later said, "For the first time in 15 years, [Alfie] questions himself as a father, a husband and as a life, it feels like it's coming to an end for him. [...] Alfie starts getting hallucinations and one in particular is quite harrowing."
Johnny Allen (EastEnders)
Johnny makes his first appearance to support Jake Moon (Joel Beckett) and Danny Moon (Jake Maskall) from the devious crime boss Andy Hunter (Michael Higgs), who they have a conflict with. Johnny soon begins appearing more often to sort out the Moon brothers' problems. After a while, he buys the nightclub "Angie's Den" (renaming it "Scarlet", after his deceased daughter) and the Ferreira family's flat, and moves in with his remaining daughter, Ruby Allen (Louisa Lytton). Johnny begins to usurp control over Andy's criminal reign, fuelling the rivalry between them, particularly when Johnny authorises his mob to unearth the body of Andy's victim, Paul Trueman (Gary Beadle). Eventually, Johnny decides to settle Andy after learning of his plot to con £750,000 from him and arranges a meeting with him. It ends with the pair seemingly going separate ways, until Johnny suddenly throws Andy from a motorway bridge, killing him on impact. Andy's death is recorded as suicide. After Jake and Danny buy stolen alcohol to use in Scarlet, Johnny fires them. After Johnny steals Danny's idea for a Salsa night at the club, Danny goes to Johnny's house in a drunken state, and sets it on fire. Johnny hunts down Jake and Danny, drives them to the woods and prepares to shoot Danny. Jake pleads for mercy, and Johnny then lets both of them go and orders them to leave Albert Square and never return. Jake, however, does return on his own in September, and tells Johnny he is there for personal reasons, so Johnny lets him stay.
