Over to the "Ministry of Science" now, where Etta sits in a waiting room. There's an Observer there, observing her quite creepily. Etta avoids eye contact and then the Observer says, "She'll be here in a moment. Your meeting. It's about to take place." Hey, way to predict that an appointment is going to be fulfilled! He gets up and leaves, right before Nina Sharp comes rolling down the hallway in a motorized chair. Unlike Broyles, she hasn't aged at all, except her hair is completely silver and, I suppose, there's also the scooter. "You wanted to see me, agent," she says, brusquely, to Etta, who tells her that they're still waiting on the touch screens for headquarters and they've been backordered now for six months.
Nina says she doesn't know how to break it to her, but her department's needs are the lowest thing on the list of her priorities. Looks like she found a way to break it to her! Then she bitches out Etta for always managing to come during her lunch hour and orders Etta to walk her to her car. Um, so to speak.
Outside, Nina's a lot friendlier and apologizes, reminding Etta that she can't her thoughts from them the same way Etta can. Then she asks if they've made any progress with Walter's device.
Etta says "Yes and no" and looks down the path. Nina follows her gaze and sees Walter, with Simon, waiting in a little urban park of wood and concrete. She's stunned and she asks about the others. Etta says it's unclear; if Dr. Bishop knows where they are, he's unable to tell them, she says. Nina asks why not.
Within a few moments of talking to Walter though, it's clear. He doesn't recognize Nina and she tells him they've known each other for many years and it's good to see him again. "In that case, it's good to see you too," he says. He gets up and starts to walk away. Simon asks Nina if she can help fix him. "Of course, you understand the risks of wanting to save the world?" she says and Simon says, "They say he did it once before." "He and his team," Etta reminds him, pointedly for reasons that are either obvious now or will become clear.
As they watch Walter frolic in the park, Nina says she can't fix him, but then she tells him about the piece of Walter's brain that was surgically removed and kept in a locked vault at Massive Dynamic. "It's entirely possible that you could use that material to inspire Walter's brain to heal itself," she says, which is utterly hysterical. Simon and Etta are a little flummoxed by the idea that Walter asked William Bell to surgically remove a part of Walter's brain, but Nina chalks it up to Walter not liking the person he was becoming. Well, he would probably hate the imbecile he appears to be now. Nina tells them the missing brain piece isn't here but at their old facility in the city. Everyone looks past Walter, balancing on one leg on a bench to the city across the river. "That's wall-to-wall Observers," says Etta. Simon says they've done harder and Etta cocks her head in skepticism at his bravado.
