Beginning February 8, “Grey’s Anatomy” enters a three-episode story arc that will challenge the interns of Seattle Grace -- and "Grey’s" fans as well -- like never before. Elizabeth Reaser (Independent Spirit Award nominee for "Sweet Land") guest stars as a patient over multiple episodes.

The execution of a former mafioso in the witness-protection programme leads the agents to a retired mob boss, an unethical US Marshal, and a jealous widow. Elsewhere, Lisbon receives a surprise gift on her birthday.

As the BAU investigates targeted killings in Tampa, they also deal with their own feelings about the loss of Prentiss.

Daryl and Carol rush Judith to the hospital. Rosita, Eugene, and Gabriel search for Coco. Maggie and Negan take arms against Pamela. The heroes assemble for one last stand.

When a drug dealer collapses on the job, he refuses to disclose personal information - fearing criminal prosecution. Meanwhile, Foreman falls victim to a practical joke and Nora catches the eye of House and Wilson.

The survivors make a deal with Pamela; the Commonwealth celebrates Founders Day.
