Buffy and Willow, moving in parallel.
Season 2 - Buffy loses her virginity, and Angel promptly turns evil, shattering all the fairy-tale expectations she had about what being with him would be like. At the same time, Willow loses her innocence, in the figurative sense, when she discovers that Xander would rather be with someone he hates than be with her.
Season 3 - Buffy (thanks to some help from Spike) realizes she can't be "just friends" with Angel and walks away from him. In the same episode, Oz catches Willow with Xander and walks away from her. A few episodes later, Buffy and Angel have it out and become a couple again. In the same episode, Willow and Oz become a couple again. Later that year, Buffy and Willow both realize that their destinies lie in Sunnydale - again, in the same episode.
Season 4 - We get the infamous Buffy/Riley porno in "The I in Team," and in the very same episode Willow spends her first night with Tara. Regardless of how much or how little Willow and Tara did that night (a question that will never be resolved to everyone's satisfaction), both Buffy and Willow hit major turning points in their respective relationships at the same time.
Season 5 - Buffy and Willow learn about "tough love" in the same episode, and finish the episode telling each other about the difficult commitments they have to make for the sake of the people they love.
And so now we have Season 6, and tonight Willow continued her downward spiral, aided and abetted by someone with the same kind of addictive behavior. Willow has turned her back on everything solid in her life, because she doesn't want to deal with the pain. Instead she's going out looking for the next big thrill. It's only going to get her into trouble.
Meanwhile, Buffy had sex with Spike.
So do I think Buffy and Spike getting together is a good thing? Not on your life. Tell me it is, and I'll tell you that history says otherwise.
There's no love in the relationship. Spike may think he's in love with Buffy, but who really knows what a demon's interpretation of the concept is. Monday night Darla and Angel seemed to think vampires were incapable of love. Regardless of what Spike may or may not feel, though, Buffy most certainly doesn't love him. And some people say, "So what?" True, not everyone thinks sex is all about love and romance. Can anyone really say that's "bad?" Well, yes they can, but I'm not going to get into that question here. This isn't the time or the place. What I am saying is this - right or wrong, good or bad, this Buffy/Spike pairing is not going to end well. Not well at all.
Meanwhile... how great was Tara tonight? She's not the only grownup on the show (Anya is too, in a wacky neighbor sort of way), but she's certainly at the front of the pack. There was a definite change in her demeanor tonight. More solid than I've ever seen her, I think. Yes, she blurted out her whole spiel without the long buildup - but she didn't stutter during it. I feel like breaking away from Willow has given Tara a new sense of freedom and personhood. Willow may have brought Tara out of her lonely darkness into the light, but Willow wasn't the light herself. I think Tara's beginning to realize that now. This can only be good.
Oh, and by the way, it's not possible for any member of the nerd trio to have seen every episode of Doctor Who, because many of the episodes from the mid-60s have been lost. And I doubt all 26 seasons are on DVD anyway.
