I don't think Nick is a loner who has no friends and who nobody likes in the outside world . I think this is his game plan which he very kindly outlined on his VT and all the self effacing crap he has exhibited is part of that plan. He has tried to set himself up for "a journey" from being "Billy No Mates" to "Mr Popular" who wins the show and the dosh. Nice try but it's all a bit too transparent and it's in real danger of being derailed by his involvement with Jade. He knows he's shot himself in the foot and he's been undertaking damage limitation.
Chloe and Danny are pretty much flying under the radar. Danny has been letting us know that he has no wish to lead Sarah on, playing the "I'm a nice guy" card. If he carries on in the same vein he could be a contender.
