Everything seems to be at face value and it's helping put him at ease, given that he's actually getting a small laugh out of him that is quickly hidden behind a hand. Perhaps this is a fine situation. "I would think most zombies would have been a living being at some point or another, I think that is genuinely the definition of how to become a zombie, is it not?" He does have a point there.

He's blinking slowly at him for a moment or two before quickly moving onto another subject, safest bet. "This place has a name, correct? I take it that it is somewhere not connected to where I am from? Because this certainly does not seem familiar to me in the slightest and I had traveled quite a bit." Also, if Hawkeye is paying attention, he may notice that despite his mostly pristine appearance that there is rather nasty torn hole of his clothes around where his heart is. The skin seems fine, at the very least. Even if he has tried to do what he can to put together a way to cover the actual exposed skin.
