Finch meets with Peck and tells him he created it. He gives Peck a passport and chance to start a new life.
Alicia Corwin is recording and listening to the conversation.
Reese continues to spy on Finch and learns that Finch had a fiance, but chose to give up his love to protect her because of the dangers that surrounded the Machine.
