You pinch your lips together and turn your back on your friends. You made your decision, you’ve filled your obligation and told them, you’re not going to change your mind, so there’s no reason to look them in the eye. You expect it when someone pipes up to stop you. You somehow weren’t expecting Karkat to be the first to say something.
“I’m not changing my mind,” you tell him firmly without turning back to face him. “Besides, with my retcon powers, you probably won't even notice, just blink and I’ll be back! Just there, a fight with a green shithead, and bam I’ll be right here again and Dave will be calling me a cool senpai and dumb shit.”
“I’m not trying to fucking stop you!” Karkat snaps, and in your shock you do turn around, then. He’s glowering at you, more determined than you think you’ve ever seen him.
“I’m coming with you!”
You’re touched, actually. It’s like a scene straight out of both of your movies.
“Aw, Karkat, I don’t mean to be rude but I’m way more powerful than you and I probably won’t-”
“I’m not going for your sake you writhing fleshmound!” Karkat surprises you again.
“I’m going back for Gamzee!”
