Immediately, he wants to ask about the hypothetical 'but what do you do if there is something stuck in there?' and he has to bite his lip to refrain from the words coming full force out of his mouth.

"Generally, you want to wait until after the bleeding has slowed before stitching things up, right?" It's been a while since he's had to think about the best practices for this, so asking not only helps to show he's still engaged, he thinks, but also to confirm procedure.
