I don't think you'll be lost but as always there was a lot of great dialogue.

As Mayer apparently has a crush on Taylor Swift now, god why do I know these things, we can only hope that one day they can combine their genius and have the most awesome song writing babies ever.

I assume the whole point of the Shaw storyline is going be Shaw driving Chuck to be able to be a more complete spy.

Well Chuck has a lot more experience at it than Awesome.

It was definitely nice to see Aceveda. 24 pulled in lot of names for the season.

I think as stand alone episodes go it wasn't bad, the problem was that with Monday's season one episode it was two stand alone episodes in a row after a long break.

I think the final lines were hinting at the eventual reaction that Peter is going have when he realizes that Walter essentially kidnapped him from his family. The fact that the subject matter of his night terrors is real and the cause is Walter.
