A new sneak-peek that has been released shows Monroe's emotional speech before the Tribunal ceremony.

He calls the tribunal sacrifice "wrong."

He adds, "What is right is my love for my wife and her love for me, that you will never be able to destroy."

Silas Weir Mitchell, who plays Monroe, dished a few spoilers about the sacrifice ceremony.

He told Tvline: "It's that thing where people who want to perpetrate a horrible act, they need some justification for it."

He added, "So instead of just throwing me onto the pike and burning me, they'll go through the proper channels and have a proper tribunal before they impale me and burn me."
