Revealing mistake: When Tomas and Brenda are avoiding the big pile of stuff down in ground in the elevator, there are wires visible pulling them.
Revealing mistake: When the Gladers are hanging upside down by their feet, they are all wearing jackets and T-shirts. The jackets all dangle toward the floor due to gravity. The T-shirts - which are not tucked in - all remain in place, keeping their torsos completely covered.
Character mistake: Near the end of the movie, when Newt and Minho and Frypan and others are all being checked by WCKD's scanners to identify the subjects. Minho is called subject A4 when he is really subject A7, subject A4 is Chuck. Newt is also called subject A6 when he really is subject A5, Subject A6 is ALBY.
Answer: He is one of the guards that works in the facility.
