Sometimes I wish we'd seen Giles exhibit that bat-wielding, fire-slinging, I'll-beat-you-to-death-with-my-bare-hands-if-need-be level of rage toward Angel when he started stalking, harassing, and threatening Buffy (and her friends) instead of far too late, when Jenny died. Like, his speech to Buffy about passing no judgment on her for having sex with Angel and respecting/supporting her instead was excellent, but... Why didn't he try harder to defend her and her friends from Angel, who presented both a supernatural threat and a very commonplace violent ex-boyfriend type of threat? Where was his anger when Angel wrote "Was it good for you too?" in blood on a wall to shame and torment Buffy? Where was his rage when Angel almost killed Willow and later snuck into her house and killed her pets in yet another blatant threat of future violence?
These are the children in his care! These are the young girls in his care who look up to him as a father figure in the absence of their own! There is an older man--a vampire, no less!--stalking them and scaring them and threatening to do horrible things to them! A monster who has a HISTORY of doing this to young girls. They are staying up all night huddled together, curled up under crosses and garlic, fearing for their lives.
Where was Giles? Where was his rage?
I can't help but think that for all his kind words, Giles was always resigned to Buffy's inevitable death and just didn't or couldn't invest the energy in her wellbeing to drum up that kind of anger on her behalf. He respected her, but he didn't protect her. If she died because of her actions and choices, even if those actions were the choices of a child, so be it. Which is patently awful. That Willow was acceptable collateral damage, too, speaks poorly of Giles' character.
That he didn't go insane with protective fury the moment Angel started personally attacking Buffy, that he didn't throw himself between them and shield her from the predations of an older man will never not infuriate me. Giles had the juice to do it, both in fighting ability and magic craft. If he had stepped in, Jenny might not have died either.
That he was willing to die over Jenny, abandoning the children who loved and depended on him, instead of defending ALL of them right out the gate is maddening.
It's just really disappointing to think about.
