This one's about fan satisfaction I think, turning the tables so Barnabas can be the vampire victim, something he never experienced before, having been bat-bitten..... he's got three bite marks on his neck. Why?? Ang just has to go back later to the Old House for seconds, specifically because Nicholas forbade it, I think. By now, he should see any effort to convince him she's obedient as meaning she's about to do the opposite.
