No such luck.
Mark wasn't even a villain-of-the-week! He was a villain-we're-taking-on-just-to-give-you-a
Granted, performance all around were good, although I think Mark was having trouble deciding on an accent. Was he a Russian mobster? German? French?
The Joker dressed as the Penguin? (which is closer to the truth than you'd think.)
Otherwise, the first episode of the last season of Chuck was fine. Hopefully it'll improve over the next 12 episodes, but I was okay with this one.
