Consider a slightly different story. Eddin and Ferris come across a strange gas cylinder and both look at the warning labels the cylinder has.
Eddin: Ah. Explosive. I better handle this carefully then.
Ferris: Ah. Explosive. I really need a ciggarette now... <boom>

I'd go with Eddin as being the more rational reaction. Ferris sees, and understands there's more to be learned, but doesn't seem to make any effort to internalise or actually understand this knowledge. Both explore, but in diferent ways. At the end of the day though, neither immediate reaction is bad. No one is required to learn something in a single moment. What matters is whether they have other reactions (and specifically, each other's reactions) in the minites, hours, and days to follow.
