I love No Future for You as well. To me Faith’s journey came full circle, she accidentally killed Genevieve while trying to reason with her and clearly has the tools to deal with it after Finch. I have such complicated feelings on Giles and Faith despite being two of my favorite character. For starters I feel like he should have been a better Watcher to her in Season 3 and this isn’t the first that she should be hearing about the mistakes Giles made in his youth. I know some fans have the opinion that part of his interest in Faith in this Season along with him leaving by his stuff to her is in part driven by his guilt over having failed her in the past and it has merit. Secondly I do think the way he went about it was manipulative, he did withhold certain info and she was clearly hurt to see that he was using her that it was all about Buffy. On the flip side of that I think that by simply asking her to kill again is a weird display of trust, believing that she won’t go off the rails again. He also demonstrates his for lack of a better term faith in Faith again when Buffy tells him that Faith tried to kill her again and Giles takes Faith’s side and goes and saves her, a 180 from Consequences. We also see Faith who was always searching for an authority figure tell Giles she wasn’t taking orders anymore and they agreed to be equals, another important step in her journey.
I see shipy subtext and while I agree that Faith is sexual I think it comes from Giles. He seems to appreciate her cleavage and there was the Steel/Peed comment. In another issue Courtney tells them they argue like her parents. I do think that it was intentionally ambiguous for two reasons the first being her age when they meet two being that there are fans that would rip him to shreds if he picked Faith’s side over Buffy’s in an argument if he was sleeping with her. I’ve read Faith and Giles fan fiction as well and I almost always like it and ship them my main concern is that it feels to me like he is only with her because he’s on the outs with Buffy.
