Continuity mistake: At the security meeting, just as Captain Lochley is saying "I agree with Sheridan", she is shown in a long shot uncrossing her arms and starting to move forward. The camera goes to a close-up of her, and she once again is shown uncrossing her arms and starting to walk forward.

In the Kingdom of the Blind - S5-E9
Continuity mistake: On Centauri Prime, Londo has an audience with the demented Regent. In the initial shot, the babbling Regent holds both hands up near his face as he speaks.
