As the show opens, a man in Hoboken, NJ seems to be crating a series of mishaps on the sidewalk. As a result, a bus driver, hits a blonde woman crossing the street but the man just walks away.
Back at the Fringe headquarters, Olivia’s back and Broyles tells Walternate that she seems like Olivia Dunham. Walternate confirms that, when tested, she responds like their Agent Dunham, explaining that Olivia can move between worlds without harm.
Charlie briefs the Fringe team in the van, telling them that for two days in a row, a Liberty Metro bus has run a red light and killed someone. It’s an interesting statistical anomaly. At the accident site, Agent Lee picks up a blue ballpoint pen near a mailbox. Charlie and Olivia are amazed – no one uses pens these days.
They find a pen near a mailbox which they are surprised about because no one uses pens anymore. It is near a mailbox where a bike messenger swerved to avoid a guy bending over, which led to the fatal crash. They realize they pen could have started a chain reaction.
Agent Lee sees a pen, just like the one from the second accident, in a photo of the first accident. At a third accident scene, Olivia sees another blue pen and she spots a man, the one from Jersey, on the pedestrian bridge above. As an ambulance comes down the street, a guy wearing headphones runs in front of it and is killed. Olivia confronts the man on the bridge, but he escapes.
