[Oh god he can... Why is Nepeta the only one he can ask to do this? He can't get Terezi because she'd try to lick the paint off. Eridan is out because he'd either complain about doing work so much that Karkat would punch him or hear it as 'fill a quadrant with me'. Sollux would mock him and Gamzee's eyes would glaze over and he'd forget what he was doing. He'd rather die than ask Vriska for more help, Kanaya would probably try to dress him up, and he'd probably lunge for John after the kid couldn't stop laughing.
So. That left Nepeta, who'd help him, and maybe hope it meant he was feeling a little flushed for her, but not just assume. It wasn't ideal, but she'd be the least likely to just... be a douche over it.]
Right. Okay. Flashlight and grey or black clothes, got it? That's an order!
