Agree with this.
Also, seems to me that people are a little disappointed because "perfect Drew" is not so perfect after all...he's merely human.
While I don't agree with his liaison with Tully, mainly because she's a total train wreck, I do sort of understand it. Drew seems to me to be a very affectionate and tactile person, he is demonstrative with his feelings and wears his heart on his sleeve. He did have real feelings for Jade, in my opinion, and when the fake marriage ended and Jade made it clear that Ed was the object of her affection, I think it really rocked him. Tully befriended him and showed him consideration and affection...things developed from there. People seem to be blaming Drew for his part in the breakdown of Tully's relationship with her gf but Drew does not know Tully's gf, so why should he care? It was Tully's choice to take things to the level that they're at now. He is "in the moment" and locked in a house where emotions are heightened to the nth degree. They have obviously talked about Tully's relationship but, of course, it hasn't gone to air for a variety of reasons so we don't really know what either of them have resolved.
I still think Drew really likes and admires Tim but is well aware of the games he is playing and knows he wouldn't hesitate to throw him under a bus if it benefitted him. Drew is merely trying to cover his arse where Tim is concerned.
