Chuck has given fans small doses of Casey's past so far but now it's time to up the ante. This week we finally get a Casey-centric episode and as hinted previously, there will be three things revealed about everyone's favorite colonel. Find out tonight in the episode entitled "Chuck Versus the Tic Tac."
In the episode, Casey (Adam Baldwin) is forced to go on a mission for his old commanding officer James Keller (guest star Robert Patrick) which puts the colonel in a tight spot. Casey eventually becomes a wanted man and because of charges of treason, he ends up behind bars.
Chuck and Sarah, on the other hand, are struggling on whether or not to help Casey out of this jam since it will spell the end of their spy careers. But after learning about Keller's dark secrets, they follow through and attempt to break Casey out of jail to clear his name.
Meanwhile, Awesome (Ryan McPartlin) and Morgan (Joshua Gomez) find out that the other knows about Chuck's secret life. Awesome also plans to keep Ellie (Sarah Lancaster) out of danger but this proves to be a big challenge especially when she stumbles on her dream fellowship.
