Dave knew that grunted acknowledgement was still acknowledgement and he accepted all forms of those, too. He made no comment about Karkat's leg against him, it was something he didn't mind and something he welcomed. Not just because he brought him food. The shuffle of leg earns a lean of body against it and despite that Dave is inwardly screaming about it, he doesn't show it on the outside, just food eating and chewing and swallowing while he uses this leg as a leaning post. "Okay so it's Chroma. Even my shit for time is controlled by it."

He set the chopsticks down for a second and shrugged his shoulder, the one not leaning against Karkat. "So if I'm going to get us home, I'm gonna have to figure out how much each jump is in whatever amount it is. That means I have to test, too, I can't take you with me if it isn't safe for you." He cared too much for Karkat to see him hurt and be the one that hurt him. "And obviously I'm not fuckin' leaving you here so, might be a while."
