You know that creepy guy in your office who likes guns and knives a little too much? Maybe he was once one of Walter's test subjects and he has a lot of metal in his blood, which effectively makes him a receiver for secret transmissions between the ne'er-do-wells at work on the pattern.
Buddy gets these visions in his head of traumatic events that come to pass, like an attack on a bus that traps the passengers in a clear substance, like insects in amber. Who possibly has the technology to make such a nefarious weapon? Do you even have to ask? Really, shouldn't the Fringe team hire someone to just stay on standby by the Massive Dynamic lab?
The bus attack was carried out in order to retrieve a small data disk from a drug enforcement agent who heard some South American drug buddies talking about the Pattern, so it's really starting to seem like Olivia is one of the few people who didn't already know about the pattern.
So since Buddy is receiving transmissions between Pattern agents, the Fringe team uses him to chase down one of them -- but he steps in front of a bus rather than be taken into custody. All this to retrieve a little disk that no one knows anything about, laments Olivia. She'd probably feel even worse if she knew that Broyles was just going to turn it right over to Nina Sharp.
What else is Nina up to? Well, you know how when you get a new computer and you use a cable to transfer files from your old computer to your new one? She's doing pretty much exactly that with John Scott.
A shadowy figure enters St. Anne's cathedral and sits down in the confessional, and tells the priest it's been three months since his last confession. Three months? Multiply that by about a hundred and that's about how long it's been for me. I feel like I should have taken notes, because I'm sure there's some confession-requiring stuff that I've forgotten, should I ever decide that I'd like to go to heaven. He asks the priest if he believes God talks to people, and the priest pretty much has to hang up the robe or answer "yes." Well, then, how about the devil? "Do you have something to confess, my son?" asks the priest.
Buddy, getting a little verklempt, says he tries to be a good man, but he sees things. And we flash through what this guy sees. A man in a suit getting on a city bus. Sitting down, he looks at the other passengers, specifically at a woman with a backpack.
"It's happening again, and I'm scared," says Buddy, back in the confessional. Scared of what, asks the apparently bored priest. "Of what's going to happen on the bus!' says Buddy.
Which is this: as the bus enters a tunnel, the man opens up his briefcase, and calmly takes out a gas mask and straps it on. This does not fail to escape the notice of the other passengers, but before they have too much time to react, the man pulls out a shiny metal canister, pulls it open an inch or so, and rolls it down the aisle. It spews smoke, and as the other passengers start to freak out, the man calmly walks down the aisle and picks up the woman's backpack.
In the church, Buddy is getting more and more agitated, and the priest has asked if he's hurt someone. Buddy bolts from the confessional and runs off through the nave.
The man on the bus steps off, totally forgetting to get a transfer. He pulls off the mask and gets into a car waiting nearby. Fortunately the bus drove into an ENTIRELY DESERTED tunnel in the middle of RUSH HOUR.
Back at the church, the priest chases the confessor, who drops a piece of paper as he hurries out. "Roy, I know it's you!" yells the priest. So much for the privacy of the confessional. The priest picks up the crumpled piece of paper, on which is drawn a black-and-white picture of screaming bus passengers. Judging from the utter sense of despair, I'm guessing this is from a Monday-morning commute.
Back in the tunnel, one police car has shown up, with one cop all, "Come on, move it along," at least until he shines his flashlight into the bus to find the passengers frozen in some kind of plastic or gel filling the entire interior. That's no excuse for being late for work! You should have left a little earlier!
