Continuity mistake: In the final basketball game #23's hair is wet from sweat and gets knocked to the ground by Mick. It cuts to the coach. #23 is standing next to him with dry hair, immediately followed by a shot of him being helped up by his teammates and carried over to the bench.
Visible crew/equipment: Stiles is surfing on the top of the van for the first time. The camera cuts to the back of the van, and a police motorcycle can be seen with its hazards on. (00:21:50)
Other mistake: When he reveals his teen wolf appearance for the first time in the garage to his friend. His friend has a T-shirt on - when he moves closer the writing appears reversed for that shot.
Suggested correction: I've watched the scene, a few different platforms, and this never happens. Perhaps you saw it on a different version and should submit a screenshot.
Revealing mistake: When Stiles opens up his locker there are a pack of cards that have been spread out to give the effect of falling out of the locker as he opens but they are already hanging at first and then they fall with everything else. (00:35:15)
Revealing mistake: You see Scott walking towards the shower and he says hi to Chubby while passing him, but if you look closely after that you can tell Scott's only wearing a mask and his shoulder is bare skin. (01:00:15)
