"Yes, I trained Anakin," Obi-Wan answers with a nod. "Though not only me. When the Jedi are young, they live and learn at the temple on Coruscant. They're taught by many of the Jedi who have come before them and once they're of a certain age, if they've become proficient, they're chosen by Jedi Masters as Padawan."

But it was always going to be the case that Anakin was his Padawan. Obi-Wan had promised Qui-Gon, after all.

He smiles a little and says, "Oh, I don't think our friend Nathan would be cut out to be a Jedi."
