Captain Sheridan's best moments

Actually, it was in Meditations on the Abyss. From the Lurker’s Guide:

Sic Transit Vir was, however, one of Vir’s best episodes; it’s the one where he decides to forge documents (using the name “Abrahamo Linconi”) making it look like Narn refugees died when in fact they were being relocated and freed.

Oh, and one of my favorite Bester lines is in Mind War. Garibaldi is on the bridge, compplaining about how he hates PsiCops when Bester comes in. As Garibaldi leaves Bester looks after him and says, “Anatomically impossible, Mr. Garibaldi, but you’re welcome to try, any time, anywhere.”
