Sansa is quiet for a moment after he falls silent - partly because she's semi-unconscious, and partly because she's trying, through that haze of dizziness and pain, to work through what he's said.

"She stopped for me," she says at last, her voice thick, and frowns a little, as though she's trying to make sense of something. "At the Cornucopia.

She's crying, she realises distantly, but she's not sure whether it's from the pain or from grief. Her arm feels strangely heavy as she raises it to wipe her eyes on her sleeve. "I thought if I went with her it would only slow her down. I didn't have a weapon and I knew I couldn't fight well. And I promised Luna, you see... I promised I would stick by her, I couldn't..." She swallows, and some alertness comes back into her face as she looks at Karkat. "At least you did something. Everything you could. All I did was pray for her."
