Watch Chuck: C.A.T. Squad

I have already admitted how much of a fan I am of "Chuck" I am, however this episode I would say is not a "must watch". The only negative of this episode was that the overall plot really didn't have any merit compared to the last five episodes or so of the rest of the season. This is what is known as a "filler" episode. 

With the that only negative out of the way, this episode was quite humorous with all of its characters - particularly the first five minutes by paying homage to "Charlie's Angels" as well as making fun of the C.A.T. Squad series from the mid-80's. 

The episode begins by going over Sarah's past -- being assembled with 3 other female agents known as the C.A.T. Squad. Chuck invites the previous Squad members to the engagement party but things go a little awry. 

In this episode:

We learn more about Sarah's past, but mostly what she was like before both Chuck and Bryce

Casey opens up to Morgan more

Carina is back! And makes life complicated for Morgan's new relationship with Alex

Chuck and Sarah have a little hiccup in the episode - but the overall plot saves it by being focused on the "CAT Squad" having a traitor
