[Rin's red gaze doesn't waver, and that's something that's typically pretty uncomfortable for other people; eventually, though, he deems himself clotted enough to lower the shirt from his lip. he folds it so the blood is hidden, eyes finally glancing down to do this task]

I'll help you, if I can. Dave would, obviously, too. And Kanaya.

[there's more people in Karkat's life, but he's made his point and he won't belabour it; he holds the shirt, with the blood tucked away in it, back out to Karkat]
