I want an episode where Sharon, Kat and Stacey are in the same room. The history of these characters are huge and they have overlapped quite a lot. Imagine if Zoe returned - that'd top it!
One of my favourite episodes was the Monday of the "You ain't my Muvva" week. All the ladies having a curry and talking about their lives, and the men getting drunk in the Vic. And then a massive bombshell at the end. They don't make 'em like that anymore.
