I liked this episode better than the last two. My problem with the opening two episodes were that everyone was somebody different. We get accustomed to the characters being one way then they changed them....basically made them all dark and evil. We began to like Peter for being one way....Claire one way......Ando one way.....etc. Then they just make the characters somebody completely different.Glad they did not waste time with current Peter in Jesse's body any longer. Did not see dark haired Claire. Linderman? This show don't need Linderman.
As for Syler, they had to do something with him. Either they had to switch him over or they had to kill him off. We are on Season Three and battling the same villian for the third season would've been to stale.
The Noah/Syler thing might be interesting.
Not sure I like the Parkman story, but that is still early. Eventually he will need to interact with others.
