John Doe HQ. Karen is sitting on the couch, doing -- what, exactly? Not assisting, not typing, not much of anything, actually. John stands in front of a mirror, whinnying about how Mrs. Ex-Prescott called him a murderer. Karen whines, "Okay, this is like, major over-share." Could this character possibly BE any more annoying? The two run through the possibilities: Could he be Steven Prescott? No. Because then he'd be fifty-two years old, and clearly, he's not fifty-two. According to Karen, only "old" people are fifty-two. She adds, "Maybe you're a vampire or something." Let's pause for a second. It's daylight. The apartment has wall-to-wall windows. Not only is Karen an idiot -- she's an idiot who has never seen Buffy, the original movie or the television show. John insists that Karen be serious. Her reply: "You could be an alien revisiting your abductee?" He pauses. She says, "Seriously? Have you been tested medically to make sure you're human?" He rolls his eyes and starts to walk away: "I'm so glad I shared this with you." Karen starts off on yet another fanciful X-Files-inspired tangent: "You could be a time traveler!" This one sticks. John turns back around. She continues, "Yeah! That's why you haven't aged at all -- you just jumped through time." John explains that the science does not exist for time travel. Karen points out that it might not exist in the now, but it sure as hell could exist in the future.
