Lucas and Caleb in “Unfinished Business”

Lucas

You know what a mentor is?

Caleb

Half-man, half-beast?

Lucas

That's a Minotaur. A mentor's like a father, a wise advisor.

Caleb

You want to be my mentor?

Lucas

I'll help you find the way, Caleb. Growing up's like groping in the dark, sometimes you need someone with a flashlight.
