Qui-Gon Jinn and Obi-Wan Kenobi in “Unfinished Business”

Obi-Wan, have you done as I asked? Have you trained the boy?

Obi-Wan Kenobi

[stands up and activates his lightsaber in shock] Master Qui-Gon? How are you here?

I am here because you are here.

Obi-Wan Kenobi

No, I don't understand. What is this place?

Unlike any other, a conduit through which the entire Force of the universe flows.

Obi-Wan Kenobi

Are we in danger?

This planet is both an amplifier and a magnet. Three are here who seek Skywalker. They, like me, believe him to be the Chosen One.

Obi-Wan Kenobi

[sheaths his lightsaber] You were right. The Force within him is stronger than any known Jedi. I have trained him as well as I could, but he is still willful, and balance eludes him.

If he is the Chosen One, he will discover it here.

Obi-Wan Kenobi

And if not?

Then you must realize, with his power, this is a very dangerous place for him to be.
