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."
Tyler Moon
Tyler arrives in Walford with his father Eddie Moon (David Essex) and his brother Anthony Moon (Matt Lapinskas), and works in his father antiques emporium. He takes up boxing, and floors his first opponent, but does not know that his other brother Michael Moon (Steve John Shepherd) paid him to let Tyler win. Tyler later dates Poppy Meadow (Rachel Bright), though she is just trying to make her boyfriend jealous. Michael manipulates Tyler into taking part in an unlicensed boxing match, and sets him up with a boxer called Artie Stiller (Maurice Lee), who is known to fight dirty. Tyler wins the fight, after taking quite a few beatings, but shortly after he collapses having a seizure in the ring. He later recovers in hospital, and when he finds out that Michael was trying to kill him, Tyler grows violent toward Michael and intimidates him for a while.
