Robb Stark
King in the North
After he and Wood conspire to have Spike killed. I think Buffy understood why Wood wanted to do it, but with Giles, she was pissed. Which makes perfect sense. I think she gets over it by the end, but would you have forgiven him? Considering how everyone turns on her a few episodes later for what they perceive to be bad leadership, do you think Buffy should have told him to leave?
