So, in theory if you're here, you've arrived from our weekly Thrones recap. If not, you may want to go there first. Ground rules again: This is speculation about where Robb and Talisa's storyline is headed, which, judging from their scene in this week's episode, "The Bear and the Maiden Fair," may be a slightly (or more than slightly) different destination from that in the books. But I'm going to describe what happens in the books, so if you haven't read them get out now. This really isn't something you want spoiled. You may also want to bail if you'd rather avoid spoiler-y (though unconfirmed) speculation. And, again, please keep any discussion of the subject in the comments here rather than in those of the main recap.
It had seemed to me for a while that in changing Robb's bride from Jeyne Westerling to Talisa, and in expanding her role substantially, Benioff and Weiss might be steering her toward a different endpoint. Specifically, I thought that, unlike Jeyne, she might attend the Red Wedding and be slaughtered along with the rest. The coming bloodbath hardly needs another body, but this seemed in keeping with the showrunners' efforts to make her a more significant (and more sympathetic) character and to emphasize her loving relationship with Robb.
