You know, part of me thought about going to Season 3 to help Faith and all, but I realized that that would mess up my whole romancing thing I mentioned. Also, I wouldn't go the Song route for a few reasons. I'd keep a few things secret (like I said, Dawn's kleptomania would never be told about to the others) but otherwise I'd reveal the future since I'm adverting it. Besides, I could exploit some of Giles' past actions as well as future ones (smothering Ben and making that guy's head explode in S8) to get Spike some better treatment. And I'd certainly get a laugh out of telling them about their actors (Anthony Stewart Head has played Frank-N-Furter in the stage play that Rocky Horror Picture Show was an adaptation and arguably sings Sweet Transvestite better than Tim Curry). Plus, like you said, save Tara. I'd also do something I doubt anyone in canon has done, visit Faith in prison (I'd also inform her of some of Giles' future respect and friendship with her in S8). I have basically planned everything out. Oh, and I think Warren would drop off the face of the earth after I showed up. Well, if you call being tied up in a cemetery dropping off of the face of the Earth.
