Only two episodes left (technically 3 since the finale is a two-part, 2 hour long episode) so unless they plan on doing a marathon M. Night Shamalama swerve-fest of red herrings and fake twists I think it's safe to assume they won't be going in that direction.
Just hope they conclude the storyline this season.
They producers said this is a self-contained storyline. I really hope it gets picked up for another season.
