"Ahh— the self-loathing begins. Good to know we’ve got that in common." He joked lightly, wiggling his eyebrows back at his other self. After a moment, though, his face turned to that of confusion.
"No, I’m the Grump. What, you’re Not-So-Grump?" He kept up the confused look for a few short seconds before laughing and shaking his head. "Nah, nah, I’m still Not-So-Grump. It’d be so weird if Arin wasn’t the Grump.”
"Life goes on, even if we get weird repeats, cool. Good to fuckin’ know.” Oh god. Oh, god, that confusion scares the shit out of you. Your whole chest clenches up and everything that second before he talks, because for a horrifying minute you thought… You thought he wasn’t a grumpling at all.
But him being the Grump would be better than even that.
“—God, you asshole. Arin’s always the grump, we’re the loser that giggles at him and tries to keep him from screaming too much, and the world goes on.” You find your laugh again, and your smile, shoulders relaxing.
