Seems to me they are just killing off characters randomly. I was disappointed to see Renee go for she was so useful. Hopefully they don't keep slaughtering people randomly.
Nadia's death kind of throws out the sisters killing each other over the Rambaldi end game they brought up last season.
I doubt they would really give up the orginal page. They didn't mention anything about the page being authenticated.
Now we know where the prophecy is heading and how far some people go to make sure Rambaldi is verified.
Remember the whole duel of the sisters bit from last season?? Its going...
Sloane is being blackmailed by Prophet 5 for the cure for Nadia.
Grace is working with the Cardinal which I don't believe to be Vaughan. The message Grace needed to get to the Cardinal had nothing to do with the birth of the child. It was way too early in the episode to be that information.
Delvin knows who the Cardinal is. I doubt that he is the Cardinal. I like the Vaughn being Rambaldi thing but that is way out there. Vaughn is just Vaughn I think part of Rambaldi's plan but never mentioned by Rambaldi.
