Willow isn't going to check in. Willow didn't like Poser, or Poser people, just liked being the center of attention as long as she could hang in there.
Which wasn't long, apparently, judging by how quickly she collapsed after the rug was pulled out from under her, and how little effort she went through to maintain. Which was no effort at all, actually - she cast off the Poser world like a bad case of fleas, because, in the end, we were all as bad as the other forces which brought her down, and fully worthy of the same disrespect.
