In the season two episode 'Innocence' (where Buffy defeats the judge with a rocket launcher) there is one BIG mistake. Zander says to Cordelia in the library 'Meet at my house in half an hour' (or words similar). The next scene is in the morning, with Buffy storming into the school and questioning Ms. Calendar. THEN, it goes to a scene with Zander and Cordelia stealing the rocket launcher! It's night time and from the past! I don't want to sound nit-picky, but come on! How could this get missed?!
