Walter: Most of us experience life as a linear progression just like this. But this is an illusion because every day life presents us with an array of choices. As a result, life should look more like this. And each choice leads to a new path. To go to work. To stay home. And each choice we make creates a new reality. Do you understand?

Walter: Deja vu is simply a momentary glimpse to the other side. Almost everyone experiences it. We feel that we've somewhere before because actually we have - in another reality. It's another path. The road not taken.
