University of British Seacouver. John and Karen are going to see a professor about the whole time-travel/physics issue. They are both dressed completely differently than they were in the previous scene. What day is it? The course this professor teaches is entitled "Physics and the Reality of Time Travel." Apparently, "her boyfriend Colin" knows the professor keeps office hours until 1 PM. Cue the annoying hippie environmentalist harassing people as they try to make their way into the building. First, it's a poor girl carrying fresh-cut flowers. Hippie Environmentalist damns her because the pesticides used to grow the flowers have endangered six different types of tiger beetle. Ouch. Visions of my undergraduate life just flashed by my eyes. He jams a pamphlet into her arms. He accosts Karen next because she's wearing leather shoes. Annoying Activist says, "Animal skins. Do you know how many creatures had to die just so you could strut around wearing the latest fashions?" John turns around and says, "None." Blah fake leather shoes blah. Then he lays his genius on poor activist: his sweater is Australian wool, and the Australian government permits the slaughter of five million kangaroos annually, because they're pests that eat the grass the ranchers need for the sheep. Pause. "Nice chatting with you." And with that, they leave a stunned Mr. Greenpeace behind.

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!
