Ergo Proxy ep6-7
Reasonably certain that episode 6 is as far as I ever got into the show. I know that killing a large swathe of your cast in the space of an episode isn't unheard of, but maybe this was the first time I'd encountered that? It's a particularly oppressive run of send offs, given that Hoody chooses death by cop, Quinn dies from her gunshot wounds and the other survivors from the camp straight up succumb to malnutrition.
I do like the cold war allegory that's creeping into the show now though.
