Yeah, she and crazy breastfeeder boy probably should be put down before they hurt someone else... because that's what is going to happen. On this show, the longer you let Crazy be in charge, the more crap Crazy starts throwing at the wall.
Then again, I trust Littlefinger to make sure they do not outlive their political usefulness.
Well, I was too... but I still liked Caitlyn. She was a great character, and she did her best to hold things together when everything went to hell in Season #1. She had five kids scattered to the five winds, and it was imperative to her (as you suggest) to bring them home again while she still could. Yet, part of it is her personality; I might want to protect my children, but letting her one bartering chip go through the wilderness, in hopes that two of her children will be returned safely? She didn't even know if the kids were there, and as it turns out, her ploy did nothing whatsoever to impact either of them. From a rational standpoint, I saw that plan as a poor one in terms of likely payoff.
