It would have served Quentin right if [spoiler] he had succeeded in killing Maggie, then finding out shortly after that indeed Alexis was really his dead wife Angelique, and she was the one responsible for all the evil doings. [/spoiler]
It would have given the cops a legitimate reason to hang Quentin, and frankly, I wouldn't have shed any tears...I've said it before and I'll say it again. I hate the 1970 PT Quentin. MB and others have given reasons for why he behaves the way he does, but I still see him as an insufferable jerk.
Not that I would have cried much over Maggie either, her being without a backbone, and letting him treat her like dirt and not having sense enough to walk out on him and take him to the cleaners long ago.
I can't really root for PT Roger, seeing as he just murdered his sister, just days after murdering her daughter and his niece.
Only person I feel sorry for at this point is Julia, trapped in that room, totally at the mercy of Angelique, who pretty much told her she would show her no mercy for not telling her Barnabas' secret (and I also think, though she would not admit it, also for RT Julia killing Angelique's devoted Hoffman) and is prepared to let her starve there. Dying in a dark room, starving to death...not a very pleasant death.
