Jack had been focusing on the fact that Karen had picked up a job, trying to decipher what it was she did exactly. Working for a man who busts ghosts? That was an actual necessary job in this city? Yes, it definitely got stranger and stranger.
He did believe in ghosts, no matter if he told people he did or not. Sometimes he swore he current apartment was haunted by the ghost of Cher... even though Cher wasn't dead. It was a preemptive haunting.
"I think..." then he stopped. Vampire? Vampire? Karen was a vampire now? This Lestat had turned her into a vampire. Well that wasn't good, now was it? Jack smiled, thinking it was a joke. "Does this mean you're going to suck my blood?" Then he giggled.
