Credit Where Credit's Due - S1-E2
Continuity mistake: During the diner scene with Keith, Veronica and Lamb, Lamb leaves and Veronica starts to go next. As Veronica starts to leave, still sitting in the booth, she puts on her hat (right after she says to Lamb "smell ya later"). The camera angle is on Keith, but you can barely see Veronica putting on her hat. In the next shot, the angle is on Veronica who is just packing up her books. She has no hat on, but then puts it on (again).
Answer: 1. No, the pep squad uniform was green and yellow. 2. He failed one of the classes, the one where they were trying to launch an egg from various heights without cracking the egg. He was pairing with Angie Dahl, who told the teacher that he didn't do anything in the project. The teacher then asked him to pick the project he worked on, and he couldn't do it because he didn't help. Then the teacher told him, "See you in summer school." He couldn't graduate with everyone else because he needed to attend summer school in order to pass that class and graduate. It's assumed that he did, in fact, attend summer school, despite all the mess that happened in the season 2 finale.
