Anyway, Olivia orders Lee into the bathroom, and she jams a wooden pallet under the doorknob to keep him in there. She hustles back to the car, just as a black van pulls up with a couple more Fringe agents hopping out. Olivia wastes only two bullets as she puts them both down while she calmly strides to the taxi, yelling for Henry to get in. They peel out of there, but not before alt-Charlie yells for Olivia to stop. She aims out the window at him, but at the last second aims to the right, at some sort of valve on the top of a fuel tank directly behind him. It explodes in a MacGruber-worthy fireball, sending alt-Charlie flying, but alive, as Henry and Olivia make themselves scarce.
A freaked-out Henry yells that Olivia's a hell of a shot. "No, actually, I'm not," says Olivia. Well, she kind of is, but that was bananas, even for her. After a moment, Henry reaches under his dashboard and rips some little device out and throws it out the window. "They won't be able to find us now," he says. "Thank you," she says. I love the fact that Olivia stone-cold dropping two agents and making a fuel tank blow up is enough for Henry to accept everything she's said. Of course, he just might not want the gun turned on him.
Anyway, back in Walternate's office, Col. Broyles is explaining the stationary blinking light on the desktop computer map by saying that Olivia must have removed the cab's tracker. "We've tapped into the surveillance cams, but we haven't picked anything up yet," he says.
Walternate asks him if he's seen the incident footage. He has, but they're watching it again, and we hear the gas tank blow up. "You know what I'm thinking?" says Walternate. Alt-Broyles says, "That there's only one person at Fringe Division who could make a shot like that." You know, say what you will about Walternate, at least he's able to concentrate. If this were the real Walter, he'd probably be thinking that he wants a watermelon slushie or considering the reproductive habits of hummingbirds or some goddamn thing. "It's working," says Walternate, allowing himself a half-smile.
Meanwhile, Henry has pulled up next to a park, confusing Olivia. "This is it. Eighteenth Street, 10th Avenue, that's where you said," says Henry. Olivia realizes that Massive Dynamic is not here and has never been built, but Henry thinks maybe she got the cross-streets wrong.
