I agree with most of that, but I don't think susie will go back in the house next door - would YOU vote her back in? Who wants to listen to more drivel about making a cup of tea and her wonderful rich husband? YAWN!!
I think the house next door will have Nikki, Mikey, Lea and Grace, cos the viewers want to see some action between Grace and Mikey, but the one going into the main house depends.
If the housemates in the main house have to choose, I think they will choose Lea, they won't want Nikki back cos she moans too much!! Or Mikey, cos they spent the longest amount of time with him. If it's down to the viewers, Nikki will be in like a shot!!
