Victor holds a knife to Xander’s throat and pushes hard enough to draw blood yet just a short time later at the cop shop there’s not a single mark on his neck. Some healing powers he has there. Of course everybody on the show has those same ones. Have you ever seen a scar on Jen’s chest from her heart surgery? I’ve got a whopper from by-pass surgery yet she had her heart totally removed. That should have left a pretty big one.
