Dave doesn't even jump. Karkat Vantas opening a door quietly is basically the most laughable idea in any universe, so he just kind of wonders if the door dented his wall at all and doesn't bother to care. He's sitting on the ground leaning up against his couch with the movie on pause at the start screen, a bowl of popcorn in his lap, and his phone nearby. He was probably also texting Rose or someone else.

"You know, I feel like havin' to specify "in a while" kind of takes away from the implication that this should be a good thing? Like yeah, this terrible thing, no worries, it has been twenty three whole days since our last murder." He's not even actually keeping track of the number. "And what about the whole stealing corpses and dismembering them for jars thing, is he cold turkey on that yet?"

He will also snag that peanut butter cup, thank you.
