Thanks. Of course, my DVDs are stuck in a box somewhere...
But a certain scene does come to mind. It's in "There All the Honor Lies," when Sheridan's listening to the music in Downbelow... and then it cuts to Kosh standing alone outside, and you get the impression that he loves the music too, but also that in a way he's keeping watch while Sheridan rests and recovers....
That might do the trick, although I can't hope that an icon will capture all the emotions there.
