So here's Barbabas.....overcome with blood lust.....unable to control himself......frantic to get away from the people he cares about, so he doesn't harm anyone else.
In desperation he flees to the weird room in the East Wing and lo and behold, he manages to get inside the place.
What's the VERY first thing he does? Bite Carolyn.
Do you suppose the irony was intended? I always hesitate to give the writers that much credit.
