Whoof. Someone went out on a night of roughousing and woke up into an amnesia plot.

"Kinda," he admits. "They had a big guy where I came from that made your head all foggy-like if you got too close to it - Sin. I don't think it's that-" because a lot of people weren't big on the 'do science' thing in Spira, "--but I wouldn't be surprised if it was something like that. Though... it's weird nobody recognised you. You didn't get washed up too?"

Started at one place or was on a boat, then ended up somewhere else. That's what it sounds like, doesn't it? If no one could help the guy remember anything else but a name.
