Inigo makes a bit of a face at the 'Medusa' part, obviously having no idea what the other guy is talking about. Probably something unique to his world, Inigo figures.

Besides, there's something much more interesting here. Something he suddenly remembers, his eyes growing wide.

"That's right! One time-- One time one of the windows broke a bit, I think. And all of us fell asleep and had these weird dreams because of it." Look, it's a while ago, so most of the details have been lost on Inigo.. But he at least remembers the outline of it all still.
