Revealing mistake: When Chang's paint bomb explodes, pay attention to the background. You will see paint exploding from three different points on the ground. (One to the center, one to the left and one to the right) The only problem is that there was only one paint bomb in the center, so it makes no sense that there are 3 explosions from different points.
Other mistake: When we see the Dean's phone contacts, they're suppose to be in alphabetical order, but "Aisha" comes after "Andres" and before "Annie." It should be before "Andres." And "Albino?" is after "Freckles."Bishop73
Continuity mistake: We know from this episode that Pierce's father is alive, but at the beginning of episode 1-7 Pierce's mother is on the other end of the phone and speaks about seeing his father's "ghost," as if his father has passed away. (00:02:00)Veronica Remotigue
