(spoilers) I believe this episode is one of the better ones i have seen so far. The pacing of the episode is great. The story wasn't as predictable as some of the other episodes.
The new addition to the cast is also very believable. I like his character and the way he interacts with Jane.The Red John story arc wasn't present this episode. Which I found refreshing for once. Usually I like that story arc and hate the 'separate' episodes. This time it worked for me because the new boss was introduced. Therefore we get some story development, especially the conversation at the end.That conversation gave us some kind of a 'set up', where later this season some sort of 'pay off' will follow. I believe it isn't a coincidence that he depicts Jane as a psychopath. Moreover he makes it clear to Jane that he is as smart as he is.
I think this episode is worth watching.
