This photo of Romijn really captures the Robin Cunnings character

It's official, Rebecca Romijn is signed on for a guest star spot in Chuck's fifth and finale season. She will be playing Robin Cunnings, an apparently "cold, calculating, and cunning CIA agent known for her rather abrasive interrogation technique", according to Entertainment Weekly. Rumor also has it that she will be part of a group that attempts to frame Chuck Bartowski for a horrible crime. The nerve of these people!

Her first appearance will occur in episode six of the latest cycle, which begins airing on October 21st.
