Familiar-looking pair of merchants
From Foolswiki
They set up shop in Sunny Waterfall Cave. It is unknown exactly why they choose this location, and why they're familiar-looking, but they might be friends of Yuri.
The Man: I think it would fit our modus operandi to have the characters say "Hey, those merchants look familiar," but never have it explained or even questioned in the story as to why they are familiar-looking. I'm not sure if that was the intention of the person who wrote them in (iirc it was KaaVink) or not, though.
