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."
Alfie Moon
Alfie discovers Ronnie is being released from prison but thinks that she will not return to Walford. He is angry to discover that she has and demands Roxy choose, him or Ronnie. Roxy chooses Alfie but Kat persuades him to accept Ronnie's presence and let Roxy see her sister. Kat supports Alfie after Michael's death and the two become closer. The night before his wedding, Alfie visits Kat and they kiss passionately. On his wedding day, Alfie tells Ian Beale (Adam Woodyatt) that he still loves Kat but marries Roxy. Roxy realises that Alfie is still in love with Kat and orders him out of the church. He learns that Kat is going to Ibiza and races to the airport. They reconcile, moments before her flight is due to depart. As revenge for Alfie's treatment of Roxy, Phil sells The Vic, forcing Alfie and Kat out. Kat tells Alfie that she is pregnant and they move in with Kat's grandmother, Mo Harris (Laila Morse). Kat has a market stall, selling women's clothes, but Alfie isn't as successful as goes to help Spencer in Australia for a while. He returns a month later and tells Kat that he has just bought a classic Ford Capri. After a night in a posh hotel, they return to Walford and Alfie sets up a burger bar on the Square but this is taken away so he sets up a men's clothes stall instead. This doesn't last thanks to a feud with the market inspector, Aleks Shirovs (Kristian Kiehling), so he gets a job at Ian's café. Kat and Alfie are thrilled when their twin sons, Bert and Ernie (Freddie and Stanley Beale), are born.
