Murmuration

S1, E3: Sato confesses to Bellamy that she was Zach's CIA handler. Bellamy tells her the story of a rogue Leviathan Group member who accessed the ancient wisdom 100 years ago and learned how to affect matter with his mind. On their hunt for the capstone, Langdon and Katherine instead find a mysterious, old 16mm film of the man - and the incredible event - that Bellamy spoke of. Peter, still in the Araf, experiences the death of his son, Zach, at his own hands. Nunez finds the body of Trish, who has been murdered by Mal'akh to send a message to Langdon: Don't disobey me again.
