Sort of. I think Kat and Alfie's return was superfluous to the show, as they've just been on the together/seperated roundabout again. I was very happy with Kat's storyline over the last couple of months, but ultimately it's thrown them together again too soon.
I would be happy to see Kat back again, but I think they'll either return together or just stay away. If that's the case, then so long as they get a decent ending, I can live with that.
I've always had a soft spot for Kat, so it's hard to see her pushed aside for Denise Van Outen (terrible actress), Phil's latest power play, another Roxy/Ronnie's husband affair, or dull Les playing away from home.
