Plus I love the fact that Xander got the chance to play a more dark, dangreous character and that he reverts back to being dorky Xander at the end.
Reverts? Or goes back to faking?
You have two major instances where Xander's true inner nature shows through. Not the one he projects for Buffy and Willow.
You could add a third one with The Zeppo in that Xander doesn't back down because he really hasn't all that much to lose.
The Pack is where he is literally unleashed, and The Wish where, as Angel states, a person's personality does shape their vampyness.
Xander (and Willow) were the Master's most vicious creatures and I would hazard a guess that Xander might give Angelus a run for his money.
Im not a fan to be honest, it felt cheap and nasty.
Cheap? How?
Nasty - yes, as outlined above and the point.
It shows you in no uncertain terms that Xander would hurt those closest to him and enjoy it if given the motivation.
Not unlike a certain vampire who got his own show.
I'm not sure what that says about the Xander/Angel dynamic.
The Pack is one of my all time, top 10 buffy episodes. possibly top 5, even. i just think it was brilliant.
One of my favorites as well.
But now I appreciate the episode for what it is-a great character ep for Xander and Willow that shows how deep their relationship is.
Yes. If Xander became a villain (which by the laws of the Jossverse is long overdue) he would be very interesting.
