I hate to say it, but even killling Joe off at this point would still have been a better exit rather than the one he got.
It was sad to hear Maggie saying that maybe Joe was just still being and acting strange. It's too bad she never found out why he had been acting the way he had when they broke up. Well, actually she did, [spoiler] when she walked in on Angelique biting him, but Nicholas wiped her memory of it soon after. [/spoiler]
Maybe David was hanging out with Quentin without taking Amy with him. Maybe Quentin ordered him to do it. It makes sense, after all Quentin was really more interested in David than in Amy due to the fact [spoiler] David resembled Jamison and in life Quentin was really close to Jamison. Not so much with Nora, Amy's look-alike. [/spoiler]
I laughed at Julia's reaction too that Chris took all three pills. Guess Julia does have some limits and concerns regarding sedatives after all.
