I'm back for a bit! Then leaving again for a while next week. 🙂
So let's see...it depends of course. Quite often, I side with Buffy. But there are times when I side with others when they are in direct confrontation. This changes, too, as I get older. For example, my 15 year old self sided passionately with Buffy in The Prom. Now, I side with Angel. He did the right thing, for sure. (Not sure he needed to leave town, but he did need to let her move on.)
Dead Man's Party? I used to side with Buffy every time I saw the scene. Now, I side more and more with Xander. Couldn't she have called the Scoobies, and her mother, to let them know she was alright? She could have had her space and given them peace of mind at the same time. She needed to think about them as well, regardless of the tragedy that had just befallen her.
The Gift? Buffy vs Giles? I think it changes on every rewatch. Giles's perspective makes more sense every time I watch. But then I shudder and don't want to think about it anymore.
Empty Places? Buffy. Don't think that will ever change.
LMPTM? Pffft. Seriously.
And then there's Spike. The guy makes so much sense to me, (when he's not doing something blatantly evil of course). When he comes to Buffy in Becoming 2. The argument with Bangel in Lover's Walk. Pangs. "You annihilated his people. What could you possibly say to him..." From Intervention onward, I side with him quite frequently in arguments/confrontations, (with the obvious exception of the AR)--post Intervention, I often at the very least understand where he's coming from and am rooting for him even if I don't agree wholeheartedly with what he's saying or with his method of delivery.
