Shane Richie revealed that viewers dislike seeing Kat and Alfie happy. Speaking to "Inside Soap" Richie commented: "People don't like it when Kat and Alfie are really happy. I never used to believe that, but I do this time around. The way that Jessie and I like to think of it is that there's the curtain in the Queen Vic that separates the bar from their home – until you go behind it, you'd never have any idea there were problems. The bar is Kat and Alfie's public stage." With the possibility that Alfie could be the father of Tommy, Richie added: "As soon as I found out, I thought, 'If Alfie isn't infertile, then surely Tommy could be his son'. Jessie and I spoke about the dates of when Alfie was in prison, and when he saw Kat before she had the fling with Michael. The writers reckon they don't match up, but we think they do. Jessie is quite adamant about it!"
