Warning: This post contains major spoilers from tonight’s episode of “Homeland,” “The Litvinov Ruse”

Allison Carr‘s decade-long work as a Russian spy came to a screeching halt in tonight’s episode of “Homeland,” with Carrie Mathison and Saul Berenson exposing the Berlin CIA station chief’s treachery via a carefully orchestrated stunt involving the help of German intelligence (the BND).

After Carrie learned the truth about her colleague in the final moments of last week’s episode, she reunited with Saul (whose whole Israeli defection has now apparently been rendered irrelevant due his hand in uncovering Allison’s traitorous activities) in an effort to lure Allison into the hands of her SVR handler, Ivan Krupin. The ruse worked, and our last glimpse of the arrested CIA official involved her attempts to convince Dar Adal that her work with Krupin was all part of an ongoing, clandestine mission to obtain secrets from the Russians, and not the other way around.
