Huck's wife took the B16 files to Rosen, not knowing he was involved in any of the cover-up. Rosen pretends to be concerned, but immediately tells Jake and Huck. Huck reveals it's his wife, and they convince him to testify as she wishes but to lie and say he doesn't remember anything. He initially does, but after having flashbacks of her and their son, he ends up telling the truth and testifying about what happened with B16. Rosen tells Jake he's decided to move forward with the case, while still trying to protect everyone. We'll see how that works out.
