I don't think even Nush knows what's going on in her head. She's doing the denial thing again, remember her telling the girls (can't remember which one in particular) that she considers herself single and then rushing to the DR to retract that? And now she's denying she fancies Scott in the DR, even though IMO, actions are speaking very much louder than words.
So if she doesn't fancy him, where does a statement like "It's wrong... the way I'm looking at you" come from? And she keeps asking Scott what she said the yesterday, I would have thought that she'd leave the subject well alone and try to pretend that it never happened, if she really isn't interested in the guy.
The thing is the longer she strings this out due to her confusion or whatever it is, the more it looks like she's just a tease and no one likes a tease. Scott is nuts about her and I would be so gutted for him if Nush continues to play this game with him.
