In the past three seasons she's been the innocent and sweet person, a tortured soul in search of her true identity.

After finding out the truth of her origin, everything seemed to settle down a bit.

Then her brother Roman regained his memories and he was the main antagonist all through season 3.

At the end of S3E22 "In Memory" it's Jane's turn to remember and she has now become the evil Remi.

Roman is gone and Remi has picked up the baton to continue...Sandstorm's mission (?).

The others of the FBI task force are clueless and in the next season 4 they'll be fighting an unknown enemy within.

Will Remi be more ruthless and deadly then Roman?

How many innocent deaths until she is stopped?

What can we expect then: redemption and forgiveness? Or death?
