Spoiler question last 2 episodes
Spoiler below-
In the next to the last episode where Lucas gets the medical instrument to his third eye/forehead it seems to pretty clearly be a white hand shown several times waiting for Lucas at his house to murder him. Then later on it's mentioned that it's the black pharmacist (the one with the comatose wife inthe hospital) in numerous ways, such as Caleb in revenge stuffing his mouth with pills as well as Lucas telling the older doctor about the pharmacist.
Seems to me it was the older doctor doing both the killing along with the blood test results coverup, not just the test results coverup.
Anyone remember it this way or did it look like the pharmacist actually attempted the murder.
