CW: vampire dismemberment. Twilight fact: Vampire venom is like glue. When a vampire looses a limb, if they get their limb back, all they have to do is lick the part where the limb attaches, then reattach the limb in question. This does not work on hair. Sarah, a newborn in Eclipse, got into a fight and had a bald spot… at least till she was killed. Source: Eclipse/The Short Second Life of Bree Tanner.
