As I understood, without subs and such, it has been a terrible episode.
Large involvement of ordinary people, like Captain Awesome, Morgan and Jeffster in a secret CIA mission.
Also, great show of sincerity of John Casey telling the truth to Sarah about Chuck's red test.
About Shaw, he scares me. I said that the Red Sarah would test out some way, and the truth is that it surprised me.
About Sarah, I've finally seen the Sarah we all knew, but in the first part of the episode she gave me a disgusting sensation. I hope now that Shaw doesn't do something crazy because at the end of it they painted that as such.
In summary, the level rose again and produced a huge season finale promises to be spectacular, which I can't wait to see.
By the way, It has been 2 episodes since they said "Chuck's going to Rome for an undercover mission"...will that happen any day?
