Anyway, they question him about the first two victims, and he explains that Jillian Foster worked with the Ivon Medical Group, which was conducting a drug trial at the hospital. Olivia shows him a picture of the third victim, Jeffrey Mayer, and the doctor knows him too, and is quite surprised to see him. Olivia says that they're going to have to question all their science and medical personnel, but he tells them that they're not looking for a doctor: "You're looking for a patient." He shows them a video about a study that the hospital started about a year ago, on nootropics -- smart drugs. "All of our test subjects started with an IQ of less than 65," he said. So the study was on politicians, amirite? The doctor says their aim was to increase their intelligence until they could function independently day-to-day, which Charlie calls a "worthy goal" and Dr. Levin all gloomily says, "We thought so too."

Then Olivia spots Milo in the background and is all, "That's him!" not surprising the doctor at all. He shows them video of Milo five months ago, with a measured IQ of 56, severe cognitive deficiency. There he is having difficulty with a simple puzzle. There he is rolling his eyes at $#*! My Dad Says and changing the channel to find something a little more challenging. And now there he is reciting the digits of pi to one-thousand decimal places while solving differential equations in his head. "That was after one treatment," says the doctor. "We gave him five." Each one increased Milo's intelligence exponentially, and the final phase of the project allowed subjects to be released to a guardian's care. And after that, they return the subjects to their original state, in order to determine if there are any permanent adverse side effects. "So Milo didn't want to be regressed, which is why he went after Cole Arnett," says Olivia. Levin says they thought it was an accident, and when Jillian was told, she was concerned that the delay in regressing Milo might compromise the results, so she offered to handle the case herself. And wound up dead.

Charlie asks about the third victim, and Levin explains that Jeffrey is a recovery specialist, who they contract with if somebody goes missing. "The thing is, I only put the order in yesterday. Mr. Mayer had not yet been assigned the task," says Dr. Levin.

So the agents get the contact info for Milo -- his sister, who lives in Oyster Bay, out on Long Island. Olivia's skeptical that they should go there, since Milo would have to know that that's the first place people would look, and Charlie makes a joke about never seeing any oysters in Oyster Bay.
