Compulsion - S1-E2
Corrected entry: At the end of the show, Gideon and Reid are playing chess, and Reid says "check in three." Gideon then puts him in checkmate with one move. We have seen the board from all angles, and it is not possible for check in three or checkmate in one.
Compulsion - S1-E2
Corrected entry: When the professor gets killed, a kid is shown trying to drink out of the water fountain, but the water is turned off. Gideon figures out that there will be no water to the sprinklers, so a fire is soon going to be set. In real life, fire sprinklers are not connected to the main water supply. Sprinklers are on a separate pump. (00:15:00)
Correction: There are times when a building sprinkler system may be completely separate from the building water supply, but this isn't necessarily the case. The sprinkler system may tee off the water main. The interconnect valves would be secured and alarmed, but that wouldn't be impossible to circumvent.
Correction: If the building's water main has been shut off the will be no water to either sprinklers or water fountains. A "typical" building has only one water main.
Correction: Watch the scene again. After Reid said "check in three", they literally show you the next four moves. The third move, Reid puts Gideon in check and the 4th move Gideon checkmates Reid. (When the camera cuts back to Gideon, the 4th move is already done and he's picking up Reid's captured Bishop).
