Of course, his eyes flick to the knife. Of course, there's a bit of distrust here. But that's mostly because Shiro's more concerned Archer is going to accidentally stick it in himself than he is about attempted murder. Besides - one of Shiro's hands is made of metal.

"I don't see anything big enough to have rabies..." That's how it works, right? You have to be a raccoon or a coyote to be rabid, right? Snakes can't be rabid, just poisonous. Shiro picks his way through the rocks, carefully watching where he steps. Last thing he wants is to step on one of said snakes.

Or, ugh, a tarantula.

"Has that... actually happened?"
