Other mistake: Due to her bionics, Jamie has the ability to leap up 1 or 2 stories of a building or balcony. However, in the episode with the spacesuit, near the end, the astronaut has launched about 40-50 feet in the air, which is roughly 4-5 stories, but Jamie is somehow able to leap up high enough to grab onto the cable and deactivate his suit.
