When Sean shoots himself in the left arm, it is clearly shown that the muzzle and barrel of the gun are all the way back. This means that there are no bullets left in the magazine. Sean fired only two shots fro this gun and, if it was fully loaded to start with, there should be at least another 10 rounds. Additionally, a frame later, when the shot switches to a front view of Sean, the barrel is back to normal as if he had reloaded the gun.

After Sean shoots Erika and his own left arm, the time shows as 05:36:24PM in the mainframe room. Four minutes and nine seconds later at 05:40:43PM, Sean has already gone from there to a medical unit, was treated and bandaged up and is putting his shirt back on. This shirt is clean and pressed, no blood or bullet hole. While people may keep an extra shirt in their desk in case of a mishap, this shirt is an exact match for the one he was shot in. In the investigation that would definitely have ensued, based on what transpired during the shooting, Erika's fingerprints would not have been found on the gun, nor would there be any gunshot residue on her hands. The pattern of GSR on Sean's hand would prove he fired the shots.

As the clock is ticking down to 6pm, Ryan Burnett receives a text message. When he looks at his blackberry, the time on it is 3:55.
