Babylon 5, Season 4: No Surrender, No Retreat

[After discussing recent events with Captain Sheridan, Commander Ivanova walks around his desk and sits in his chair.]

Susan Ivanova:
Speaking of which, as of now I'm relieving you of command.

John Sheridan:
[slightly amused] Ivanova, your sense of humor has always been on the edge of good taste, but—

Ivanova:
I'm serious, John.

Sheridan:
[defensively] On what grounds?

Ivanova:
You haven't taken any personal time in over nine months. And in that time we have broken away from Earth, fought a war, you have been declared dead at least once, and you know how tiring that can be.

Sheridan:
There isn't much chance of me winning this argument, is there?

Ivanova:
None whatsoever. I never give up when I'm right. Your only option is to surrender.

Sheridan:
Who taught you to negotiate like that?

Ivanova:
You did.

Sheridan:
[impressed and defeated] Oh. Well, then I assume this enforced vacation is to begin immediately.

[Ivanova has already picked up papers from the desk and gotten to work.]

Ivanova:
Started when I walked in that door.
