Tom Builder and Alfred in “Legacy”

I won't see this church completed.

DA?

Nor will you, Alfred. Nor you, Jack, most likely. I may see it roofed. You might see the interior well on its way. But it might be 50 years before it's finished, which is why I teach you. That's why you must never stop learning even after I'm gone.

Learn from who?

From your pupils. Your younger masters, they might find new ways to perfection.
