How does it make sense for the traitor to be york?
A bug in the matrix with punk records makes more sense than York being able to hide stuff when all the punks synchronize with each other everyday..
And even leaving this aside ,if York was the one giving the orders,the moment she fell from serasnake petrification (which doesn't make sense btw) S-snake wouldn't be able to disobey Lilith's order.
All in all I think the spoilers might not be true since they make circles since yesterday (sunday)
