Such a great show. Humans were rarely the most interesting people. I wish there could've been a much better remastering than what we got, but it's still worth watching. The way everything slowly accelerates through the end of season 4, by which the pace is breathtaking. You can't take time to do that any more with streaming shows.
The title is a quote from Ambassador Kosh, (the weird looking tall guy in the space suit in the center of the picture.) Said quote refers to events in the TV show Babylon 5. He is basically telling either Captain Sheridan, Commander Sinclair, or possibly Ambassador Delenn, that it is far too late to try to change what is about to happen.
The picture in question is of the primary non-human ambassadors and their support staff.
From Left to right Vir Kotto (attaché to Ambassador Mollari,) Ambassador Londo Mollari of The Centauri Republic, bassado Kosh of The Vorlon, Ambassador Delenn of The Minbari Alliance, Lennier (attaché to Delenn), and Ambassador G'Kar of The Narn Regime.
It doesn't help that the first half of season 5 is the worst part of the series(well, barring Day of the Dead). It took ages for me to push through that, but the rest was a satisfying conclusion.
