I remember a while ago (last year?) someone mentioned that when you're in 'Dream World' and Kiros wins a battle, you see him do the Yevon prayer. I've just been playing FF8 again and indeed it's true

Anyway, I got to Fisherman's Horizon and followed the Master Fisherman's little sidequest which I've never done before. Eventually you go talk to him in the inn and he calls up a hologram (what looks like one of FFX/X-2's spheres) of Dobe, the mayor of FH, from his younger days in Esthar.

He's wearing a Yevon priest's robe

At least, it looks very similar, to me.

Just thought that added some extra amusement to the interesting coincidences.
