Peter Vincent's continued survival
I'm curious as to why Jerry did not track down Peter Vincent sooner.
Peter publicly advertises his show and reputation as a Vampire Expert so it would not be difficult for Jerry to find him.
Jerry doesn't seem the type to leave any survivors so why didn't he track down Peter during one of his shows where he would not need permission to enter? He avoided the Penthouse for its protection but the stage is free.
Never confuse the impossible with the improbable
