The Passenger

Alicia: The schizophrenic discussions are conversations with the unconscious.
She's a mathematical genius. She can't explain why. She knows math but doesn't know what math is or where it comes from in the mind. The thalidomide kid and the others can't communicate fully to her in the same way as Kekule dream supposedly gifted him the structure of a benzene ring.

Bobby: a man growing up in the atomic age. He's grappling with everything that entails and his own struggles with purpose. He lost his sister and the love of his life. He's lost, confused, shut off from love, has abandoned science. He can't live without Alicia and not living means no more Alicia.
There's something about quantum entanglement here.
