Fever dream or real?

Somewhere in my mind I remember this, but cannot find the episode.

Set in the future after Sheridan is dead. A group or reporters are talking trash about Sheridan, saying how he was a warmonger and horrible. An old Delenn hobbles into the room and tells them how great of a man he was. After she leaves, the question that could not be her because she should be dead by now.

Now, did I dream this up, was it part of one of the movies? I just got done watching season 5 and did not see that scene.

I am now racking my brain to figure out which episode or movie that was in. Please somebody set my mind at ease and let me know. It’s like having part of a song stuck in your head and you need to hear the whole thing to get rid of the frustration. Thank you.
