Oh boy, getting his cheater of a girlfriend riled up is entertaining. Tantalizing bits of schadenfreude that promise something bigger and better if and when their revenge is finally set in motion. Or at least I hope it will.
I also just really hope he doesn't screw up and get them found out one of these days. If anybody's gonna do it, it's more likely to be him and not the smart Touko. Meanwhile, seeing Karen spout such nauseating hypocrisy is quite amazing in and of itself.
