Clay explored his memories within the Animus, touching on the formative events of his life.
- William: So we're in agreement. Reach your goal, then get out of there.
- Priest: The Lord is my shepherd, I lack nothing. He makes me lie down in green pastures, he leads me besides quiet waters, he refreshes my soul. He guides me along the right paths for his name's sake. Even though I walk through the darkest valley, I will fear no evil, for you are with me; your rod and your staff, they comfort me. You prepare a table before me in the presence of my enemies. You anoint my head with oil; my cup overflows. Surely your goodness and love will follow me all the day.
- Clay: And, then, we all got up and marked our favorite jobs on the board. I'm going to be an astronaut, dad.
- Harold: Did you hear your son? The kid wants to be a spaceman.
- William: Clay Kaczmarek, few are offered the opportunity I now give you.
Prove yourself, novice, and you will be one of us.
Together, we will defend the free will of humanity from those who would steal it.
