Last night’s Fringe marked a huge reversal from the past two weeks’ filler episodes and gave us some real answers about shape-shifters and traveling between universes. In The Man from the Other Side, Thomas Newton opens a portal and gets someone he referred to as Mr. Secretary through to our universe. Peter, trying to stop Newton, realizes almost presciently that Walter kidnapped him out of the alt-world when he was young. And of course, angrily, he runs away. Now, I find it implausible that Peter could be angry at Walter for saving his life, but let’s take a look at the science of last night’s episode, shall we?
