Continuity mistake: When Reid is talking there's a big crack at the top of the window that might be a problem since they're supposed to be flying. Then a few seconds later they cut back to him and it's filled with putty. (00:05:00 - 00:06:00)
Other mistake: A mugshot of a suspect is showing with some personal information. Name, license number, address, etc. The field for "Home address" shows a valid address but "Work Address" shows "Male." The correct field title should be "Sex." (00:40:00)
Continuity mistake: When Garcia accesses the bank's page online Prentiss gives her the account number login, 1552 9384 6729, and we see Garcia typing it correctly on the screen with the password, but when it cuts to the account's page showing deposit and balance, we see in the balance box the account number's last four digits are 7629, not 6729.
Continuity mistake: While Morgan and Prentiss are at the crime scene talking to the homeless man, when Morgan moves the tent and finds the text written on the wall, the homeless man smudges the text with his fingers, but when Morgan sends a photo of the evidence the smudges and text differ.
