Continuity mistake: Right after Cordelia has her vision, Wesley goes to the whiteboard. In the "Case" column he writes "N.D.U.O." Underneath what looks like "CARYNSS" crossed out.

Continuity mistake: The 4 Space Rangers (Carlos, TJ, Cassie, Ashley) morph on the overhanging gangway, then jump off to the ground below. We see them hit the ground, and in the very next shot, they're right next to the Galaxy Rangers, and Andross, who are on the other side of the courtyard. There wasn't enough time for them to move that distance.
