^^^ Still, I'm not sure if Greer rejected Bailey. After all, she did the advances (in spite of the fact that she met him before while he was just a kid). She kissed the young lad on his forehead after chatting with him about dealing with the breakup from his date and insisting that she "set him up" with who would turn out to be his childhood playmate (from 7:30 to 9:00).
[That date didn't turn out to be interesting for him, BTW.]
From 17:10 to 18:30, she chats with him about that date, and reminisces about someone similar to Bailey that she fell in love with during her college years. She then kisses him on top of his forehead - again.
The big part is brief, from 19:55 to 20:15, where he enters the bathroom and inadvertently sees her nude (frontal). However, as per the conversation above, he will remark later that he was surprised she didn't turn around.
In the next scene, she leaves the kids in the middle of the night after a conversation with Bailey. Of course, Bailey knows better and chats with a friend of his, who encourages him to chase her to her hotel suite.
Upon entering Greer's hotel suite, there's stuff that leads to the conversation above. After Bailey finishes his glass of water, Greer holds his hand up.
