"It's--" He starts, but comes up short. Because that's not anything remotely close to what he thought this little rock might be. A piece of her home. The one she died to protect. Something she cared enough about to die for. And she's giving part of it to him. That's a lot to think about. He's not even sure what the hell to make of it, all he can do is sit there, stunned and slightly light-headed from the booze, staring. First at her, then at the rock in his hand.

"No. No, that's not selfish." It's kind of the complete opposite, actually. If anything shows that she really cares about him, it's her doing this. Giving him a piece of her home. Something to show him that...he's not alone. Not entirely. He still has Juliana. And she still cares about him. He still has no idea why, considering his behaviour toward her in the beginning, but...he's glad. Because she's become important to him somehow. Another thing he's not certain how to explain, but...he cares. And not only is this gesture of hers incredibly meaningful, it reminds him that he's not as alone as he thinks he is.

"You don't have to..." He trails off before he can get the 'do this' part out, the words just sort of falling as his gaze drops to the piece of the Rubble again. It's a big gesture from her. He gets that. He understands, and he appreciates it more than he even knows how to convey, or maybe even realizes himself in that moment. For a few long moments, he's silent, but eventually he speaks up again, voice quieter now. "Thank you."
