Willow always comes through to Buffy.. she does so in Weight Of The World and she does so in Normal Again.. and who knows how many times more. But their friendship seems to be a one way road.. always has been. Ok, occasionaly Buffy saves Willow's life.. but that isn't actually a best friend thing to do, being the Slayer and all.
Willow has no best friend. Just watch Something Blue. The only people who always care/cared for her are Oz, Dawn and of course Tara.
Tara's best friend is Joel.. I think.. or it might be that I am confusing fan fic and canon here.. but actually I don't mind, hee
