Fringe: Olivia. In the Lab. With the Revolver.

I thought this was a terrific episode of Fringe. Olivia had not been sleeping well because she was keeping Walter's tremendous secret about the origin of Peter. In an effort to find a cure for her insomnia she sought out Sam the bowling ally guru who helped her work out her problems earlier this season. Sam was folksy as per usual but did not give her much to work her woes and she went about her merry way.

This left Olivia to have very tense moments with Peter throughout the episode. I guess Nina was right about Olivia going to her to be talked out of informing Peter of his true identity. Olivia is very happy with her pseudo family unit and does not want to mess with it. Even though her and Peter could obviously be something more.

On a side note, when did Astrid become comic relief? Her warning Walter to "not mix up the spoons" was about the only humorous thing that happened in this entire episode. Good for Walter for wanting to come clean to Peter. I cannot wait to see what happens when Peter goes back to the alternate universe all grown up! Are both his parents dead in his dimension or will Walter get to meet Walternate and have to answer for his crimes?

I was slightly frustrated because the audience knew this was a "Cortexaphan" case well before our heroes but I was extremely happy with the resolution of our case of the week. Olivia had a "Gregory House" moment while talking to Sam the second time around which was a lot of fun. Unfortunately Sam was about to reveal something much more interesting than the "Cortexaphan" connection.

Sam said to Olivia, "I'm much older than I look, much taller too". Olivia was originally referred to Sam by Nina Sharp, William Bell's right hand. Sam and Olivia have an odd relationship which I first thought was sexual tension but now realize is something much different. Sam looks towards Olivia in the way a father would look towards a daughter and she reciprocates by seeking his advice and guidance. Olivia does not know it yet, but it is my belief that Sam is William Bell.

The biggest hint that Sam is William Bell is the title of this episode. Why would the creative forces behind this show pinpoint the "Clue" scene as the title if something extremely important was not insinuated in it?
