Character mistake: Near the end, just before Derek and Danny depart at Danny's high school, Derek says to his brother "I saw a car cruising by the house last night when I pulled out of there with Seth." The car that was shown driving by their house the previous night was in a brief scene right after Derek and Danny took down all of their nazi posters, and before Derek took a shower. He had not just 'pulled out of there with Seth.' The last time he had seen Seth at this point in the movie was at Cameron's party where Seth had almost shot him.
