Steve's mouth thins into an unhappy line at that, but it makes a certain amount of sense, based on what little he knows. And clearly Jack knows more, has been here longer.

He can't help but wonder if there's more to it than that, but - well. There's only so much they can do with the evidence in front of them, until there's more.

That line grows into more of a concerned frown. "Are you all right?" Issues is a pretty damn vague term, and maybe that's intentional, but it's not like Steve can help asking, all the same.
