Once again not a great episode and little arc beyond Peter's haunting, but I liked that Timeline Olivia grew in character bringing her closer to being our Olivia. Walter also finally felt three dimensional in his relationship with the kid. This season has cleverly presented the other universe as the cool kids, almost like the old Apple/IBM ads, but it's left me feeling that what I liked most about the show was gone. This might have been intentional with Peter's absence, but I'm glad this episode at least brought us closer to having the old group back. And for that reason I give it a one thumb up.... at least when Peter returns we've seen these boring people more as themselves. Now let's get on with it before the ratings are so bad Fox has to stop showing them until rerun season.
