- We catch up with Scotty and McCoy at the Plexicorp plastics factory. McCoy is pretending that Scotty is a famous Scottish professor there for an inspection. It works like a charm.
- Meanwhile, Sulu is admiring a helicopter. He asks the pilot if he can ask some questions about it.
- Back at Plexicorp, Dr. Nichols, the head of the factory, brings Scotty and McCoy into his office.
- Scotty tells Nichols that his factory has a problem: they're still using polymers. He claims that he can show them a production method that would reduce the width of their plastic by one-sixth. That's huge. Or tiny.
- McCoy suggests that Scotty use Nichols' computer, which Scotty hilariously thinks is voice-automated. He even uses the mouse like a microphone.
- After getting the hang of things, Scotty performs a series of insane, rapid-fire calculations that explain the process of creating "transparent aluminum."
- Obviously, Scotty and McCoy are trying to make a deal, so they step away for a sidebar. McCoy is worried about changing history, but Scotty is totally blasé. Go for it, dudes?
