It's also interesting to reassess Giles' words and actions over the 'No Future For You' arc if we assume that he disapproves of Buffy's fundraising activities:
Then of course in #9 Buffy insists on knowing "exactly what the hell is going on?" and Giles says "No. I don't want you to be any part of this." Maybe that's not because he wants to protect her as I'd assumed, but because he no longer trusts her? Buffy's stricken expression takes a whole new meaning now. She's got a guilty conscience, and Giles is rubbing her face in it by making his attitude clear. She's willing to let Willow help him because she knows deep down that she's in the wrong, but she's feeling abandoned because she thinks she's made a controversial and courageous decision as a leader, and nobody is backing her up.
And at the end of the arc, Giles wants to help Faith 'play social worker to the Slayers' because 'there are battles you and I can win" before the big war starts. I wonder if he's thinking that the Slayer who needs an intervention more than any other is Buffy herself?
