So do I. They really shouldn't have brought her back at all. To me she's just a rehash of her character from HO, but in that she was good, now she's just irritating. I can't stand her on EE.
As for Jack and Ronnie, I really don't see them working now or anytime in the future, he slept with her sister and that too was just so random! I'm not really liking Jack anymore, I don't get where they are going with him. Whilst I agree that he is much more likeable with Tanya, I don't want them together either, I mean that's his brother's wife.
The whole thing is getting weird and incestuous, Max/Stacey, Max/Tanya, Sean/Tanya, Jack/Tanya, Jack/Ronnie, Jack/Roxy, Roxy/Sean.
