In the books, all Sookie ever says is that she does whatever's necessary to avoid seeing inside Terry's head, because it's such a nightmare in there, and I've always liked how the show lets that stuff coexist with the wonderful things about him. So I guess it's within the show's mandate to give that its due, but of all the parallels the show likes to play with, I think this one would be the most harmed by becoming explicit in the way it's been presented so far. So here's hoping this Private Ellers is the main crazy in the tale.
Sookie overhears Lafayette giving himself quite the epic pep talk, down in the Eric Northman Cubby Suite, about how he should probably go ahead and off Tara while it's daytime. I sort of underestimated and underreported his agency in the conversation last week, but rewatching last episode after seeing this one clarified the arc a little more for me: They're both accountable for Tara's fate, but Lafayette was definitely the main person. Sookie was horrified for a second when he suggested, and it was clear that he was doing it solely out of freak desperation, which is why -- thirty-six hours later -- it makes sense for him to have had a change of heart.
Sookie: "Lafayette, don't!"
Lafayette: "I turned her into the thing she hates most..."
Sookie: "Duh, that's always going to be Tara Thornton, more than vampires. She once hated herself so much she became an entirely other person. Actually three times that has happened. Every season, in fact. Before Tommy Mickens Merlotte, we had Tara. Don't sweat it."
Lafayette: "What if she doesn't come back?"
Sookie: "Well, that's not a given. Jessica took a second. And even if she doesn't, we're her family. We can take care of her."
Which also gave me pause, I won't lie. That's a very scary idea to be flirting with, this "feral vampire as dementia patient" thing. But I really don't think that's where it's headed, so you can just look at this as symbolic of their love for her, that they'd commit to doing that instead of putting her down. But man, for a second I got way icked.
