this was one of my favorite episodes of CHUCK. i generally like any episode where chuck and sarah's relationship gets developed more, and this episode shows just how far sarah is willing to go to not just protect chuck's safety, but also of his every day life because she knows how important his family and friends is to chuck. to me, she didnt even hesitate in making the decision she chose, i was expecting it; it was the most logical and easy and safest course of action, especially given how she feels about chuck.
this episode also adds plot twist between chuck and sarah as well, and we can see just how strong they feel about each other and whether their relationship can endure sarah's choice.
another reviewer mentioned the angle FULCRUM has taken which is also great, considering everything thats relating to fulcrum in past episodes and a lot of times it revolves things happening at the buy more, its not much of a leap to think a clandestine agency like fulcrum can't put two and two together.
hopefully i didnt have specific and obvious spoilers written into this review.
great job chuck's cast and crew, and happy holidays to everyone reading this little post
