Meanwhile, Walter's discovered that his theory was correct: "The organism was developed from the same material that Olivia stole from her captors." Peter asks if he's sure, which seems to piss Walter off a little as he says he's not even sure if they're on the same plane of consciousness, but yes, he's sure about this.
Over at Boston Federal Building, Broyles confronts Harris about the way Olivia was arrested, and Harris says he had "reason to suspect she might be dangerous," and Broyles says Harris has a "vendetta" against her, and speaking as a diehard-to-the-end NYPD Blue watcher, I've seen quite enough subplots about internal reviews overseen by hardasses to grudgingly come to respect the work that's done by the unit, so forgive me if I gloss over this somewhat. But it's probably important to know that the Fringe unit is now under Harris's "purview," and that he says he's not out to punish some "JV agent" who tried to ruin his life "for chasing a little tail." This is going to get worse before it gets better.
Back over at Boston College, Olivia's talking to the TA, asking if there was anyone unusual in class lately, or if Kinberg said anything to her in private. "Why would he?" she says. "'Cause you were his teacher's assistant," says Olivia. Yes, that's right: the percentage of televised teacher's assistants who are sleeping with their professors is holding steady at one hundred percent. (Call that the Law & Order Rule.) After the TA unconvincingly dances around questions Olivia asks about discrepancies between when his office hours ended and when he would go home, she finally comes right out and asks her how long she was seeing the professor. The TA doesn't even bother trying to deny it. "Three months. I knew he was gonna take the job. He hadn't even told his wife about it yet." Olivia asks her what job, and the TA's reluctant to say, even though she kinda just blew it, because Kinberg hadn't even told his wife yet: "The CDC -- Centers for Disease Control. They offered him this big job, which meant moving to Atlanta." She tells Olivia it was for a task force to oversee the country's preparedness to fight off an epidemic.
