Certainly there was some expectation that there might be a trap, but nothing like this; fire and explosions had not been the norm in any of the other ruins. Perhaps later he could consider who or what set the trap, but at the moment Sam was a bit stunned, having been tossed backwards a bit onto his back. There were certainly sore spots and a ringing in his ears, but for the most part he was fine, Fortitude having guarded him slightly from the fire.

He's quick to get to his feet though, eyes darting about to take in what had happened, registering that someone was yelling to get down the stairs. Jim immediately catches his attention, seeing the man unable to get up from his hands and knees. "Jim," he calls out, though it comes out as a rasp that probably couldn't be heard, before hurrying over to help him get to his feet.

There isn't time for him to see to any injuries, not with rocks coming down on them, but he does at least send out a quick group healing spell that should help with some pain and some minor injuries.
