Dave is still afraid. There is a part of him that will always be, he thinks. He has accepted this about himself. There is another feeling coursing through him too, though. It’s something he's felt before, though never quite so intensely. He looks up at Karkat and understands, viscerally, the simple power his words have. They pump through Dave’s own body, alive and warm and true.
He wonders if Karkat realizes it, or if he’s just, as always, saying what he feels as he feels it. Dave doesn’t attempt to dissect it further. There will be time for that later.
