Angel is in total control. She doesn't drink so can, and already has, sussed out a situation, such as when Alex came to B2. That's why she wasn't a fan of events at B1 and didn't go...
Some might disagree but I thought there came a point when the girls wanted rid of them. The DJ kept asking Rose something and she kept shaking her head, and I think the girls said no, tomorrow. He questioned why. At that point Angel went to her room, mumbling stuff to herself and didn't look too impressed...that was also after he grabbed her arm...
He also upset Rose and followed her to her room to apologise...Very strange morning indeed...
