Hmm, apparently we don't think a lot of this episode or rather don't have a lot to say on it.
Although this episode never sticks out prominently in my mind when I think back on the season, whenever I watch the episode itself I always thoroughly enjoy it.
And even though she was evil and she hurt Giles, I really loved Gwendolyn Post. I thought she was an excellent character (And thankfully played by an excellent actress) and really, in retrospect, it's a shame that her betrayal didn't last over a few episodes rather than it all just happening in the one. It would have been a nice mini-arc, we would have had more fun with her character and her chemistry with Giles and it would have made the betrayal and her death even more shocking.
And this was our first Buffy and Faith fight. Who else had been waiting for this to happen since Faith showed up? They were just too getting-on-y since the events of Faith, Hope and Trick and I was just waiting for the tension to pop up again. Haha. And it was a very nice foreshadowing of the hand-to-hand fight in Graduation. Faith initiating the first kick, smashing through the window, fighting outside...
