When the CIA targets Vivian Volkoff for assassination, Chuck turns to an unusual ally to protect her: Vivian's father, Alexei. Ellie suspects her mother doesn't want her to find out about her father's past. Join us for our discussion of the 20th episode of the fourth season of Chuck, Chuck Versus the Family Volkoff, which originally aired on April 11th, 2011. I incorrectly called the last episode number 18. It was written by Amanda Kate Shuman and Nicholas Wootton. This is Amanda’s first writing credit. It was directed by Robert Duncan McNeill.
