"That's good." Sincerely, both for the fact that Ianto isn't injured too badly, and that he was doing vital work. Jim, on his part, didn't expect to be down in the thick of it - but he's got disaster control experience, and helping with evac and the close proximity of the Outpost and Wyver... some of it's a blur, but it's also not surprising to him. Kirks aren't built with brakes.

"Something else is wrong, though."

Not a question. It doesn't take the 200 year old telepath hiding in the latent corners of Jim's mind to see that, in Ianto, just someone used to spot-counseling subordinates and friends through trauma. (His own trauma, you ask? Ha ha why would he need anybody for that, how ridiculous.)
