Loved the ending...okay, loved the whole thing, but loved the "as a heartbeat", as opposed to a heart attack.  Hee!  & I'd feel badly for Xander, but he was a major jerk!  Screw him!  Though I guess Willow feels obligated to save him, and maybe when he deals with his trauma, he'll apologize and mean it.  I did like the Spuffy talk about school..especially that Buffy wouldn't let him convince her to play hooky.  I did like the little bit letting us know the Harris' are aware (on some level) that Sunnydale isn't exactly the safest town to live in.  Great update! :D
