Eleanor: Dude! Not cool.
Michael: Disagree. I think it's the coolest thing I've ever done. Do you really not see what's happening here? Do you want me to spell it out for you? This is a defense mechanism, Eleanor. You saw yourself fall in love with Chidi, and it freaked you out to see yourself be so vulnerable. So, you're using determinism to convince yourself that those feelings were not real.
Eleanor: You know, you don't know me, man.
Michael: Yes, I do, I know everything about you, remember? Including that nothing scares you more than vulnerability.
Eleanor: [scoffs] Whatever. Who even cares?
Michael: I do. Because if everything is determined, and we have no free will, then all the stuff we're doing to put more good into the world is pointless. And I want to believe that it matters. So if you'll excuse me, I'm gonna use my free will right now to go pick up our friends at the airport. Worst possible use of free will, but I'm gonna do it anyway, because I care about them.
Waitress: You might wanna head out too. We're closing soon, and the second we do, they use this place to shoot porn.
