Season 4 doesn't really let up on the break-neck pacing, does it?
Sheridan's return - wonderful. I've watched that scene so many times. And Lennier's face... Trouble with a capital 'T', right there.

The growth of Vir Cotto - brilliantly done, he's such a fascinating character to watch. Yeah, the weight loss makes him look a lot older but it fits with Vir becoming more of his own man, uh, Centauri, in this season.

Garibaldi - he ended okay, I thought, in the end?
