There's a sliiight moment of contemplation, but it doesn't take very long at all before Inigo just says: "Sure."

It's not like it could hurt, right? Even though he has absolutely no idea of what he'll find once he's looking through the odd device.

"W-What's this? It doesn't even look like a leaf!" It's hard to tell if he's impressed or confused with that tone. Maybe it's both.
