I can't keep any of this straight, when and how did real Red die?
It looks like by the time Liz gets all her answers she'll be just like Red. Then Red (or Dembe) will help her hide the same way Katarina did.
Ressler will hook up with Liz and be "killed" in the finale for knowing too much. It'll be a cliffhanger ending but he'll survive and be back to old Ressler and ready to take down Red (& Liz?) in the final season.
