It seems that every time I think that maybe I'm going to stop bothering with Fringe they throw a really good episode at me to confuse me. LOL!
I think this episode really demonstrated what an amazing actor John Noble is (as if there was any doubt) and I loved that Peter seems to finally understand how Walter works. Even Olivia wasn't too annoying in this one. Hehe!
I just thought it was really clever how they showed just how much progress Walter has made, and what he went through going back into the asylum.
