Karkat has been acting strange lately -- calm, unflappable, and sometimes even smiling dreamily at nothing -- and while it's something of a respite from his usual yelling, it's gone on long enough the others are concerned. They make vague plans to find out just what the hell is going on, but John, as the only person who can still get under Karkat's skin, decides on a direct approach... and discovers some very interesting things indeed about his favorite shouty troll and his unnerving moirail.

John introduces his best human friend to his best troll friend. Maybe the three of them sit down to watch romcoms, maybe they're just hanging around a lab in the veil, but whatever the circumstance, Dave has trouble paying attention to the conversation at hand. Karkat is good looking and distracting and it's just not fair. Naturally, he begins distracting Karkat while John's talking. Little touches, lip licks, etc. Karkat gets flustered, Dave is thrilled, John is oblivious. It turns into a competition to see who can flirt the most without alerting John to their UST-fueled game.

It just figures that when Karkat finally finds that special someone he hates more than he hates himself, that person turns out to be the guy who's essentially his clone, but fifty million times more annoying.

Dave and Karkat have a little fight over who pushed the buttons that swapped their species, and it turns into extensive scientific experimentation of a different kind altogether.

You spend the hours after you wake up pacing your hive, your stomach threatening to upturn and your bulge threatening to unsheathe. You're excited to the point that you're dripping with more than just sweat, yes, but you're also beyond nervous. Besides what you assume are the usual worries -- what if he doesn't show up, what if he takes one look at your butlerbot and is so unimpressed -- there's also the tiny little fact that you've never done any of this before. At all.

"I kind of... accidentally fantasized about Karkat while we were doing it. Which I do sometimes, not when we're messing around, just like-- uh, fuck, look, I'm--" Terezi puts a finger over your lips and you stammer to a stop. She nestles closer and sighs happily. "You too, huh?" You stare at the ceiling in bewilderment. Whatever response you were expecting, that was not it.
