Having just finished up with season four in an all-out Buffy-binge, I can totally see this relationship working. I'd forgotten the power of their spell in Primeval and then the aftermath in Restless. Damn, now I can't wait to get through seasons five, six, and seven with all this stuff in mind. Nice job with the countless intricacies :)

Also? ...you know you've been in fandom too long when an OT3 is the logical solution to a love triangle. Best line in the whole thing. And so true!
