So that clears up the age thing for Derek. Slightly older than Scott and Stiles who at the moment are 17 ish so that would put Derek at 20. Doesn't seem right, he looks older than 20.

Scott and Stiles are around 15-16, because they're sophomores in the pilot. Allison is 17, which is why she didn't want anyone to know it was her birthday early in S1.
