What a perfectly creepy story line. Not being a wormy or buggy-type fan at the best of times this whole concept was just...wrong! Wrong enough to be a completely perfect and wonderfully out there, Fringe episode.
Walter as a "free man" wandering around China Town was a bad idea waiting to happen. In perfect counterpoint, his unparalleled brilliance and his overwhelming naivete both serve to get him in trouble, and it's hard to tell which one is the culprit at any given moment. Best to keep your mouth shut, Walter!
Peter's "other" life was showing it's face tonight in his knowledge of the Asian gang details as well as his fluency in Cantonese. Just who did he "go wrong" with prior to being conscripted by Olivia and the Fringe unit, and will that help or hurt in the coming war?
Even Astrid got to step out tonight. Unfortunately, she got her as-trid kicked doing so! But she did get closer to Walter, and in the coming conflict, I think walter is going to be "the" man to know...
