Like most things involving Feferi, her interactions with Karkat are slightly traumatic. For him, that is. She’ll hide behind corners in the veil and burst out at him –EXCIT—EDL-EY, she’ll follow him down corridors whispering about horrorterrors, she’ll threaten to have sloppy makeouts with Sollux when Karkat’s in the room. It’s a very long and antagonistic list, and she wraps it around Karkat’s head on a daily basis. But it’s good-intentioned teasing! In one of their horn pile discussions, Sollux practically enlisted her to help Karkat keep his mind off of his leaderly pressures, and that’s what she’s doing!
Karkat avoids Feferi. He was always wary of her and her connection with the horrorterrors even before she started invading his everything. But if he so much as hears another glub glub bouncing gleefully down the hallway, he’s going to flip every shit he’s ever owned right into Sollux’s face.
