So when you asked if I were proposing that Buffy were in love with Gigi you meant to ask whether I were proposng that Giles believed Buffy to be in love with Gigi?
Umm... it was supposed to be a joke.

I just find Giles to be an enigma. I wish we'd get inside his head, 'cause I can't. (And that's v. unusual - getting inside character's heads is what I love doing. Without that insight, what's the point?)

I look forward to the next issue with great anticipation
Me too. I'm just not raising my hopes very far.

But it strikes me that another reason for Buffy's black mood after hearing Giles's refusal to involve her is that she now realises how badly she misjudged Faith and feels guilty about that.
Well that's a neat idea. I don't think that's it, but it'd be nice.
