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."
Michael Moon (EastEnders)
Michael is described as a competitive and manipulative risk-taker who lives dangerously, and a charmer with an eye for the ladies, but he is willing to stab anyone in the back. Shepherd said that "on the surface he's a loveable, cheeky chappy, but underneath he has hidden depths which will be exciting to explore." Shepherd opined that viewers would be unlikely to vote for him in polls such as 'sexiest male' because his character is "duplicitous": "I think viewers tend to fall in love with the character you play, and if they go for a duplicitous rogue, I'd be very surprised!" He told "What's on TV" that Michael can be mercenary and has a cruel streak, but "there's darkness and light to him, really. Some moments you can see him being really quite cruel and then the next he can be quite compassionate and thoughtful." He told "We Love Telly" that "[Michael] takes pride in the way he dresses and he's always been quite successful with the ladies." Daniel Kileklly from Digital Spy called Michael "enigmatic", and said he has a nasty side. Kirkwood compared Michael to Ronnie and Roxy's father, Archie Mitchell (Larry Lamb), saying they approach life and treat people in similar ways. The "EastEnders" website additionally calls Michael a "sinister", "flashy" and "jealous" man who "wouldn't think twice about screwing people over—even those he loves". It continues to read: "Michael possesses all the charming characteristics of his loveable rogue of a cousin Alfie, a cheeky-chappy with a silver tongue and an eye for the ladies, but with a more sinister and cruel streak. Michael is a serial womaniser and with a string of broken hearts and failed marriages behind him, he’s got the track record to prove it. Whenever he needs a port in a storm, there’s a girl he knows that will put him up for a night, a week or more." The "London Evening Standard" dubbed Moon as the "Albert Square psychopath"; Shepherd has described the character as a "functioning psychopath".
