I read on another website that, according to the TV Times, EE are planning to bring back Jean Slater in the summer.

I think this might mean that Stacey's brother might make an appearance too. I think EE need to be carefull with this though, as Stacey is in danger of being overused. Still it could be interesting. I really hope it is the same actress who played Jean last time as she was really good.
