Really don't like the english subtitles Netflix used. For the ep4 preview, it says, "now that I've been cured, you're going to betray me?" when it should be, "now that I'm trying to live, you're going to betray me"? Similar, but totally different considering the context. There were several mistranslations like that throughout the episode, but that one was most egregious.
