After episode 4x11's promo, I'm starting to doubt they will save Raven, BUT they still might, I haven't lost complete hope. Although I do think there is a way for Raven to survive, using the nightblood way, there has to be something why else would they show a clear, long shot of TWO nightblood vials. I feel like Raven won't die, but what makes me very mad is that nobody even cares about her, at least not yet... Maybe they will ask about her next ep, I hope so because it's not logical that they forget about their friend like that.
