Root and Reese in “Unfinished Business”

Root

Hey, eyes on the road. Keep your mind on navigating. Can't afford to lose any more time.

Reese

You really are sure she's alive.

Root

You know about Schrodinger's cat? There's a cat trapped in a box with something lethal. There's a 50% chance the cat's been killed, but until you open the box, there's no way to know one way or the other. Quantum physics says before you open the box, the cat isn't dead or alive. It's both.

Reese

What about after you open the box?

Root

Reality collapses back onto itself. Cat's either alive, or it's dead.

Reese

Well, we're gonna see reality soon. But you don't bet against Shaw.

Root

No. Nothing kills that cat.
