Of course it's hard to listen to - he doesn't want to imagine her in pain. But of course he still wants to know. Anything like that, it's part of what's made her who she is, and he wants to understand her, what she's been through. And it's a lot easier to help if you know what someone's struggled with.

He doesn't want her to hide things like this to protect him. Keeping him out of investigations is one thing, but this is personal.

So he listens quietly, keeping his own emotions in check as well, squeezing her hand a little to let her know it's okay to go on.
