The final piece of prophecy is Girl killing Kris.
Kris was depressed and suicidal after Dessapearance and his family breaking apart, that's why he got roped into this plan - "If you're going to die, at least die saving the worlds"
This explains why he is so uncomfortable around Noelle - she is his future killer, after all.
This explains Snowgrave - he is supposed to condition Noelle for his own murder.
This explains why Ralsei was hoping that Prophecy will change if they switch the Girl and make her kind.
This explains Susie's reaction - she was genuinely shocked about it (she thought that Prophecy is a good thing), but she quickly found a cope - after all, there's no way in hell she would kill her best friend?
