Stein and Ray in “Unfinished Business”

Stein

I know how it feels.

Ray

What?

Stein

To have a crisis of confidence. As unlikely as it might seem, I know. It was 2002. I was teaching quantum mechanics, and I had one particularly gifted student. He was able to solve the Ehrenfest theorem in less than an hour. He was, quite frankly, the only student in all my years of teaching who ever made me feel inferior. That student was you. You were exceptional.

Ray

And suddenly, just like that, you remember having me in your class.

Stein

I always remembered. I just enjoyed taking you down a peg or two.
