Janet and Eleanor in “Unfinished Business”

What do you think happens when people walk through the door? It's the only thing in the universe I don't know.

Eleanor

I don't know either. The wave returns to the ocean. What the ocean does with the water after that is anyone's guess. But as a very wise not-robot once told me: "The true joy is in the mystery."

Do you mind if I stay here until you're gone?

Eleanor

Only if you say that thing I taught you.

...I hate to see you walk through the final door at the edge of existence...but I LOVE to watch you leave.

Eleanor

There we go.
