It had been a long time since he'd been shown compassion, before Castiel. He'd been convinced that Metatron had been trying to show him compassion at some point, but that had proven false.

He turns to Lilith when she speaks, then, wiping the drop of blood on the sweater he's wearing so that he doesn't get it into her hair when he brings a hand up to it. No matter what images the motion brings to his mind (her dress is on the floor, his hand is tighter in her hair than it is now), he makes sure the touch is gentle.

"I will do my best."
