Dialogue

 * William: We are not public figures and never submit ourselves to the hollow quest for fame. We move through clouded spaces.
 * William: Beware the easy path. Knowledge grows only through challenge.
 * Harold: You're retiling the roof at noon, Clay.
 * Clay: But I'm working on a history paper.
 * Harold: Let it slide. The foreman's son just finished engineering school and he's pocketing 60k a year. Now, that's where the money is.
 * William: They will throw obstacles in your path to distract you. But never lose sight of your goal.
 * William: You have proven yourself worthy. Today, commit to uphold the pillars of our Creed. We are Assassins.
