Question: Why do they still have gravity when Romilly asks Cooper to turn of the spinning, when they neared the wormhole? The centrifugal force stops, but on the inside there is still gravity.
Chosen answer: They do not still have gravity. Romilly is actually floating, but nothing is ever shown from behind his back, so the floating is gone unnoticed. In fact, during some shots of Romilly, you can see his feet floating behind him.
Question: At the end of the movie, survivors of the group that entered the maze reach the lab, barely making it through alive and having used a code that only an experienced maze runner would know. How did Gally arrive only moments after them, when he had elected to stay behind in the Glade at the time the group entered the maze?
Chosen answer: As it turns out, Gally was being mind-controlled by the people who operated the maze. This would explain why he was highly against any form of escape plan. When the others escaped, the operators gave him some form of safe passage straight to the control room.so he could kill the others. Best guess is, they re-activated the elevator for him and he took that route...but that's left ambiguous.
Question: Before leaving the plane, the doctor smirks, and after leaving he furtively looks back. He's supposedly an innocent, so why does he do this?
Answer: At no point is he shown smirking before leaving the plane. In the two shots he appears in before he is shown exiting, the first he is wearing an oxygen mask, and the second shows him straight-faced and helping someone to the front. The reason he looks back after going down the slide could simply just be to see who is coming behind him, or he could be examining the damage to the plane.
