Something should be done in the comics about Buffy and Faith being the last two "natural" Slayers in the line. All of the current crop are only in existence due to Willow's spell. A story line could be built around that one simple fact. Something like, this many Slayers existing at one time causes some sort of metaphysical overload in the world, so most of the newbies have to be shipped off to Mars or something (Kennedy could be the leader of the Mars team) Parallel realities and alternate universes have been done to death in this sort of thing, but someone with Joss' creative ability should be able to get rid of a whole bunch of the little buggers in a reasonable manner.
That's pretty much what season 8 was all about.
Kinda. The impression I got from their last encounter is that Buffy was incredibly thrilled to have Giles back in her life- in whatever form- and as she and the Scoobies were fussing over him, all that 'good feeling' momentarily bled over onto Faith being there. I can't see Buffy's reactions coming organically from anything else.
After the thrill of the battle victory had worn off no doubt things would've been back to the way they were before- so Faith did the sensible thing and left.
Bearing in mind the last time Faith had been around any of them Buffy was upset about Giles 'picking' Faith over her his will and Xander was apparently staring hate-daggers.
1) That's still the healthiest that the Buffy-Faith relationship had ever been. At the very least, it's the healthiest that it's been since 'Amends'.
2) While Giles' return was definitely a big factor in Buffy getting along with Faith, it's not like Buffy would have hated Faith if Giles didn't come back. In season 8, in Tibet, Buffy and Faith actually got along well, despite being in tough circumstances. Later, when Giles died, Buffy was clearly upset about Giles leaving his house to Faith (How could she NOT be upset at that time?), but she still didn't fight with Faith or anything - she and Faith got along well, and they were both very mature about the whole thing.
So, when Buffy and Faith behaved so friendly in season 10, I didn't see it as a "temporary glow" over Giles' return - I saw it as another step in their reconciliation, which had been progressing slowly since season 4.
I wanted to post that comics page here (it's a lovely moment!), but for some reason it doesn't get approved. Oh well.
3) Don't forget that Faith and Willow ALSO got close in season 9, in addition to Faith's close relationship with Giles. So, I think that if Faith became a scooby, she'd get along pretty well with most of the gang.
I understand you find it frustrating, but I enjoy it. Faith had to be edgy and dangerous and different to Buffy. Faith is the one who 'deals with' vampire children, now can you imagine Buffy doing that? If they actually became friends Faith would be changed by that friendship, and that the change wouldn't be good for her character or for the drama/conflict. People say that Spike is simply Buffy's lapdog, now toothless and a shadow of what he used to be (I don't agree but I understand where they are coming from) and I can see the same being said if Faith and Buffy become friends. Faith would slowly lose her edge, she'd end up becoming just another scoobie. And that really would be boring
Gotta disagree here. The big problem that tends to occur with ANY long-running story is that the writers become afraid to change things. People love certain things about characters (their goodness, or their badness, or their rebelliousness, etc...), and the writers become afraid of changing that. THAT is the biggest problem I have with Spike in seasons 9 & 10 (I still love him, mind you) - he's no longer as dynamic as he was in seasons 2-7, he doesn't change as much. Good characters need to change, or they become boring. Spike's problem isn't the fact that he's "Buffy's lapdog" (he's not), it's the fact that he's too static. If the writers want Spike to be as interesting as he was in the TV show, then they need to change him as quickly as he changed in the TV show.
And the same is true of Faith - her arc in the TV show was extremely dynamic. She managed to go from good to bad, and back to good, over the course of less than 20 episodes! That's why Faith was so interesting.
And fortunately, unlike Spike, Faith remained just as dynamic in the comics. She still continues to change and grow, and that's a GOOD thing.
As for the relationship between Buffy and Faith - I think that their relationship is kinda like Iron Man and Captain America's relationship:
They started as total opposites, with Tony being a rebel (like Faith) and Steve being a boy-scout (like Buffy). Then, they started changing into each other - Buffy/Steve got more rebellious, and Tony/Faith got more responsible. And ironically, over time, they ended up replacing each other - Buffy/Steve became the rebellious one, and Tony/Faith became the responsible one. As Faith said:
This is great. This is EXACTLY how character development should work. And this continued in the comics too, fortunately, and it should continue even more, IMO. Let Buffy get darker and more rebellious, and let Faith get more responsible and mature.
And if you put Buffy and Faith in the same story together now, with them both being so opposite in such different ways, then it could be a terrific story. Let them be friends for a while. And then let them get torn apart again - but this time for the opposite reasons.
I'd read the hell out of that story.
