Over at the Fringe lab, Walter's going through the ZFT manifesto (and circling the superscript y's) when Peter comes in to ask if he's found anything "new and exciting" in there: "You've read the manifesto about a dozen times cover to cover. So just wondering." Walter says he needs to show Peter something.
He gets out his old typewriter and rolls in a piece of paper while Astrid strolls in to ask what's going on. "Show and tell, apparently," says Peter. Walter types a few letters, then rips the paper out and hands it to Peter. It's the word "prophecy," with an elevated "y," just like in the manifesto. See, he had to type something ominous, so it seems worse, right? He couldn't have just typed "cuddly."
"The typewriter's Belly's. I remember the day he purchased it. It was raining," says Walter. Peter disbelievingly says Walter's saying William Bell is not only the funder of ZFT, but he wrote the manifesto and is responsible for everything that's happened.
But Walter doesn't believe it: "William Bell was many things. He was ambitious. He was egotistical. He was temperamental. But he wasn't a madman." Walter points out there are references throughout the manifesto to the chapter on ethics, but there's no such chapter in the copy. "It is missing. And I believe that someone has removed it to suit their own evil purposes. And I can prove it," he says. While Astrid goes to answer the ringing telephone, Walter says he aims to get another copy of the book. Since Bell wrote the manifesto right there in the lab, Walter figures the missing chapter could still be in there. "And what if you're wrong?" asks Peter. Walter says he's not, and when he finds the chapter, it will absolve William Bell. He looks quite distraught over this. But before Peter can do anything about it, Astrid comes back in to say Olivia's on the phone.
So it's over to New York City, where the Fringe team checks out the combustion scene. There are two charred figures on the pavement as the group strolls up. And it should be noted that Walter's carrying a Slusho. Which can only mean that while they were en route to the scene, Walter made them stop at a convenience store so he could have a SLUSHO.
