Karl built something no licensing board would approve: a device that syncs his brainwaves to his patients’ through sound and water, while psilocybin hidden in the tea breaks the wall between conscious and subconscious. It’s illegal. It’s unmatched. But the door he opens in them is opening in him.

Suho learns what’s in the tea and walks. Not betrayal, but because it’s the right thing to do.

Edward poses as a private investigator. He’s really Karl’s brother, certain Karl massacred their parents and sister as a child, then fled. Karl believes it too, the way he believes a heart condition is slowly killing him. A drug lord, Karl’s first patient, invites him onto his yacht to settle a deal. It becomes Karl’s breaking point.

Edward uses the collapse to force one last session, drags him through the night they both survived, and hands him to the police. A year in, a cellmate who knows gunshot wounds spots the scar on Karl’s back. Not heart surgery. A bullet. There was no condition. There was a gun, but it wasn’t Karl holding it.

Edward drives away believing he’s won. The truth is already in the car with him, becoming his breaking point.
