Dr Alex just wanted a girl to show interest in him so he didn't look like a total loser, the reality is he couldn't wait to stop pretending he was interested in her. He's about to do it for the second time.
He's not been interested in any girl really, and there has been all sorts in there and let's be honest, some of the girls are gorgeous. He just pretends then soon as he can he's out of there.
I really don't respect him at all. He's dishonest.
