I am so excited at seeing Sean!
Do you remember all those rumours a while ago about him pushing Bradley and Stacey to the end with their relationship? I think him being an obstacle in their path would be very good! It could be like the Dennis/Sharon/Den situation.
I heard Sean is actually more evil than Den. If he's staying longterm I don't think he can go as far as Den did, but he could still cause some havoc. I would like to see Stacey and Bradley really fight for their relationship. Sharon ended up with Dennis after Den had a go, it could still work out. Of course they had to move abroad! lol. but still...
Actually I can see Stacey being a lot more harder to manipulate than Sharon. I don't think she'll allow Sean to dictate to her what she can do.
