With Casey (Adam Baldwin) incarcerated Decker (Richard Burgi) offers Chuck (Zachary Levi) and Sarah (Yvonne Strahovski) a deal to get their friend out of prison by delivering to him the world’s most dangerous computer virus.
To get the virus the pair will have to infiltrate an nudist cult, convince the designer (Eric Lange) of the virus to give up his greatest creation, and find a way to work with their rival (Carrie-Anne Moss) who wants Casey out of prison just as much as they do.
The plot gives plenty of opportunity to Sarah and Gertrude to bond while kicking some ass as well as give us a look at Chuck falling back into full-on hacker mode. The B-story involves Morgan (Joshua Gomez) and Jeff’s (Scott Krinsky) attempts to get Lester (Vik Sahay) to admit to his wrong doing and agree to respect the new Jeff (and, you know, not poison him anymore).
Throw in a late double-cross and a grisly end for one of the characters and Chuck is off and running on its final story arc. I’m going to be sad to see it go, but if this episode is any indication it looks like the series plans to go out with a bang.
