Actually I think the flash forward was supposed to be the destruction of Babylon 5, where Sinclair and Delenn and baby David escaped at the last moment. From the original storyline. I think the shuttle the Centauri prophetess saw escaping the station's destruction was their shuttle too.

But I really like Jeff and Mike bonding over the Food Riots on Mars.

That's a good point about Zathras. I'm trying to work it out, but it's making my head ache. All good time travel stories do...
