Okay. Guy in a lab coat fiddles with big shiny silver machines. He and Doe discuss the probability of time travel, paradoxes, and Albert Einstein. I'm honestly too dumb even to transcribe what they're actually saying, so you'll just have to make do with that. In short, Dr. Time posits that time travelers would have to have their memories erased as a "cosmic safety switch designed to prevent paradoxes." Wait! I think Fox has just solved the mystery of time travel. Quick, someone tell Marty McFly. In addition to not having any memory, people who travel through time are super-geniuses. Karen speaks up: "Lay it on the line for me, Doctor -- is it possible that my friend here traveled back to 1968 and ate some chick there?" You know -- John wouldn't want anyone to know why he's seeking this information. Plus, the woman wasn't eaten; in fact, the cause of death wasn't specified, and honestly, why would she freak Dr. Time out in the first place? Someone needs to sew up her mouth so it eventually grows over itself. Any. Way. Dr. Time doesn't care whether or not Doe might in fact be Hannibal Lecter circa 1968, and responds, "There is one way to find out for sure. Get an MRI." Karen: "What will that show?" Dr. Time thinks that time travel is like sending a fax -- information is transmitted from point A to point B, but some bits are lost, or altered, and the MRI results will show if there are any fissures at a molecular level. What's a fissure, you may ask? Well, it's a telltale sign of time travel, of course!
Okay. The University of British Seacouver has an MRI on the premises, in the science lab. How expensive are those machines? Any reason a physics department would need one, other than to test for time travel? John Doe lies on the bed, awaiting his test. The technician tells him he'll have to remain very still. John blabs on about the origins of the machine, and by this point, even the technician doesn't care. He presses a button, and John starts to move back into position for the test. But wait! The patient "thinks" he feels claustrophobic, and orders the technician to reverse the bed. John pants heavily as the bed comes out to its resting position. "Karen," he shouts, "I'm claustrophobic! Learn something new about myself everyday." Aw, newfound phobias, how fun. Yawn. From the scan room where they view the results, Dr. Time asks, "Is he always like this?" Karen responds, "It's complicated." Dr. Time speaks into the microphone: "I think we'd better sedate him." Cut to a drugged-out John Doe trying to figure out what on earth they sedated him with. The technician reminds him to lie still, because the test will become quite loud. Even when he's sedated, he's a never-ending fountain of information: "I know. Did I mention that I know everything?" The internal eyeballs of the poor technician roll around and around his pretty little head. The button is pushed, and John's bed starts back into the belly of the beast. The machine whirs and beeps. The technician starts tapping away at the keyboard. John looks absolutely freaked out. They're not getting any picture, because something's interfering with the scan. More machines beep. Apparently, there's something metal inside Doe, and it's distorting the magnetic field. John starts screaming; then he smashes his head on the machine, which triggers a memory. It's a flashing white light, a human image, and what looks like water. He pulls himself out of the machine and whisper-screams, "I saw something!" Then he takes off, hospital gown and all.
