There's a pause where he wonders if this isn't a trans-culture hitch in the idea of 'kiss and make it better'. Then he realizes it really, truly isn't that sore.

And then, after a moment of twisting to get a good look at it, he realizes that she does actually mean 'fixed' - He would judge that bruise to be a few weeks old, not a few hours.

"Well God-damn." He murmurs, thoughtfully, as he continues to eye his shoulder.

(He'd be lying if he said there wasn't some part of him that immediately cut and run with the implications of this and what could be done on the Starship level, someone who doesn't need instruments or even a partially functioning Sickbay to heal. But she has her own problems. She's not here to fix his. Except, evidently, those having to do with bruised shoulders.)
