Chuck - Episode 5.06 - Chuck vs. the Curse

The title of the episode is “Chuck vs. the Curse”. We already know that Rebecca Romijn is the big name guest star, playing a rogue CIA agent who likes torturing people just a little too much, but here’s a new tidbit: her character could have been played by either a man or a woman. Way to be equal opportunity, Chuck writers! Joining in the fun is Simms, an intense, slightly creepy CIA agent who may be what Team Bartowski needs to defeat Romijn. Or not.
