John's in a car headed back to the Wheeler Defense Lab at MIT.
John has to go teach, and he's not excited about it.
He's also mad that he's sharing the cover of Fortune with a bunch of other folks.
Scene 17
John's in the classroom, and he basically tells the students that being in class is going to be a waste of time. Well, at least he's honest?
He closes the window to drown out construction noise.
Apparently, it's quite hot closed, so a girl in the class goes to the window, opens it, and asks the construction workers to stop. Hmm, that was simple enough.
John is obviously intrigued by her.
Scene 18
The creepy guy who was staring at John at the Pentagon shows up outside John's office building.
Turns out, he works for the Department of Defense.
The guy takes John into a restricted area on campus as they chat.
John had thought that all those buildings were abandoned, but apparently not.
The dude, whose name is Parcher, tells John about an operation that he wants John's help with, since John's such an ace code breaker. It's kind of a continuation of the task he went to the Pentagon to help with.
Suddenly, we see John undergoing some supersecret spy prep. He's asked to memorize some content, and the folks at DoD implant him with a tracking device.
Yikes, this looks like heavy-duty stuff for a mathematician.
Scene 19
Back in non-spy-land, a guard is escorting Window Girl from John's class into his office. She asks what he's working on.
Apparently, he had left a problem on the board, and she said she's solved it.
Oops, she spoke too soon—apparently she made a bad assumption in working out the problem and got it wrong.
At least John thinks that her solution was "elegant," though.
He tries to return to his work, but she continues standing there.
Oh, now her stalling makes sense: she wants to ask him to dinner.
John is super-awkward about the invitation, but he tells her to leave her address with his office and he'll pick her up Friday.
Oh, and he finally gets her name: Alicia.
Scene 20
John is taking Alicia to a fancy party.
He's a bit distracted, but Alicia is pretty successful at getting/keeping John's attention.
They bond over staring at the stars together outside.
