Getting a BJ so that her neighbor sees it...no. Especially when she begged that the neighbor not see her/find out. This made me hate Vaughn a little. Grace is not yet in love with him, she should've just up and left him. This scene is just not sexy. 
 I'm more on board with the scene up on the roof, though why he would let an army of waiters see them like that... Better, not yet there. 
 I like that he's spoiling her, though at this point I'm not sure he does it cause he cares about her, or if it's something he does with all the women in his life. If Vaughn's is genuine or not is questionable. 
 Still not quite happy with Vaughn so I'm placing this on 3 stars. Though if I could, I'd give it 3 1/2 stars - I'd have to like the characters more to give it 4 stars.
