Dawn. Kip. Kissing. Lip mikes cranked up to ten. Cameron accidentally bites her. More smooching. Dawn runs her hand up Trip's arm and then up to his face. The camera angle changes to show that he's now wearing his vamp face. Granted, I don't go around playing much tonsil hockey with vampires at my age, but wouldn't you feel the transformation? Dawn opens her eyes wide in surprise. Well, I guess this should clear up any nagging doubts as to Dawn's familial ties to Buffy. It proves that they really are sisters. Sisters who obviously have as their family motto, "Vampires. Not just for staking anymore!"
Buffy barges into Spike's crypt, but he's nowhere to be found. She calls out to him, and he steps out from the shadows somewhere, busting on her for not knocking, then asks if Giles has caught up to her. After he expositions the Dawn situation, Buffy strides to a chest and tosses Spike a crossbow, saying, "We have to find her."
One of Sunnydale's many cemeteries. Giles plods through the mist, waving his flashlight beam around. He hears a girl scream and doesn't run, but rather briskly jogs in the direction it's coming from. He shines his light onto a vamp feeding off a teen girl backed up against a tree; he assumes it's Dawn and backhands the vamp with his flashlight. Giles goes to check on the girl and discovers Forehead. I don't know how Giles even knew her, but there you have it. By this time Zack has recovered. He claims that Forehead was asking for it, but what he really means is, "Let's you and me fight now. Old fussy dude." Giles is more than willing to oblige. He gets his ass kicked around a bit, but then remembers that he saw Karate Kid on TBS and does this front-kick thingy that sends Zack into a nearby tree, impaling him with an conveniently-placed branch in the process.
