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."
Kat &amp; Alfie: Redwater
Richie said that as "Redwater" is a stand-alone series, there is no reference to the "EastEnders" locations of Walford, Albert Square or The Queen Victoria pub, though Alfie does mention that he once worked in a pub, being the only reference to their time in "EastEnders". Kat and Alfie's twin sons, Bert and Ernie Moon, do not appear in "Redwater", because Treadwell-Collins knew that having two small children in the series would have "limited Kat and Alfie and they wouldn't have been able to do as much", though revealed that they were originally due to appear, but "suddenly you ended up having storylines about who is looking after the twins and on a show like this we needed to tell other stories" and confirmed that Kat and Alfie have only left them for a few weeks and check on them during the series.
