(As We Know It) (Part II) - S2-E18
Character mistake: Meredith states that she cannot remember the last time her and Derek kissed. Derek says that the last time was when they were still dating, but it was actually at the end of season two episode three, after Addison arrived in Seattle and Derek and Meredith had stopped seeing each other. (00:40:00)
Suggested correction: She is referring to the last time they kissed without any issues. The last time they were good.
(As We Know It) (Part II) - S2-E18
Continuity mistake: The scene where the bomb explodes shows the bomb squad captain walking toward the end of a hallway. Just as the bomb explodes you can see he is about 5-6 feet away from the end of the hallway where another bomb squad tech is waiting. After the explosion the scene cuts to Meredith flying backwards then to a shot of windows being blown out then back to a rear shot of Meredith hitting the floor. Notice here that a second floor is not visible at the end of the hallway. The scene finishes with a final aftermath shot of the hallway as the debris settles. Here we see an entirely different hallway with a visible second floor and the end of the hallway extended by about 10 feet.

Continuity mistake: When Derek is talking to Meredith on the hospital balcony and they are eating a sandwich each, in one shot Derek is taking a bite from his sandwich, then in the next shot he is suddenly holding it down at waist level.
