·          In the long winded speech the professor gives about time we see a shot of the clock. However note that the second (not the minute hand) has completely broken off and is sitting in the bottom of the clock. This is from when it fell off the wall in a previous take.

·          When Paige is brought in the time of death was said to be 4:31. After Tru revives Paige the clock on the wall of the test room says 5:10. But she didn't die from the experiment, she was murdered by the neighbor. So shouldn't her time of death be much later?

·          There's an absurdly large amount of bruising on Paige's arm in the original timeline, given that she only had one needle injection given her by a med student - the one that occurs on the day of her death. She doesn't have any previous injections, because Tru checks her arm in the second timeline and there's nothing there.

·          Despite the fact that Paige died by strangulation, Davis, Tru, and the delivery guy a;; fail to notice any bruises on her throat, broken trachea, etc., but only spot the bruise on her arm that couldn't have possibly been the direct cause of death.

·          The exterior of the building where the med students are conducting their flatline experiments changes color between the wide and the close-up shots.

·          When the student gives Paige her injection to "kill" her, it's through an IV tube that clearly isn't hooked into her arm where the supposed needle mark is.

·          Colleges of the size we see here have MCAT tests throughout the year - at least four a year. There's no reason Tru would have to wait a year to retake the test.

·          The proctor at the MCAT tests is really, really bad. First of all, you don't just let people wander in three hours late. And second, someone handing somebody else something paper-like (when Tru hands the kleenex to the guy behind her) would be grounds for expulsion.

·          MCATs cover chemistry and biology, not medical knowledge.

·          When Paige and Tru are walking through the University grounds they're perfectly dry, but in the background you can see people who are playing frisbee who are soaked to the skin (it was raining the day they filmed in Vancouver).

·          Paige wears a metal necklace for her "session" even though she knows her partner is going to use a debibrillator to revive her - she'd get electrocuted.

·          Despite the fact the med students are conducting their experiments in what appears to be an abandoned building, it has fully functional electricity for the lights and the defibrillator unit.

·          Where does Paige's father think she is? Her car's outside the house but he never saw her - does she just park outside and wander the neighborhood without saying Hi or Hello? And how does Tru know that it's Paige's car - she's never seen Paige driving the entire episode.

·          When Davis checks the eyes of the "dead body" in the original timeline, her eyelids are clearly twitching as he holds them open.
