Rich has talked a little bit about this before, so it doesn't come as a shock, but...

"...Oh."

Grif instantly regrets bringing it up. It wasn't worth the joke.

"Sorry."

He goes quiet after that, not sure how to rebound off of this. Making stupid comments to lighten serious shit? He's good at that, but it's different with someone he'd feel bad about hurting. Grif isn't as reckless with Rich as he is with other people, he's earned that much.

It makes things more awkward, though.
