Elementary: Pick your Poison Recap
Synopsis of 05×10: It is Joan’s turn to get framed as a prescription supposedly written by her appears in a murder case. She and the team work to clear her name and solve a murder to boot!
Joan told Sherlock, after Shinwell left, that she had connected with a gang detective in the Bronx who was willing to take on Shinwell as a real informant. Sherlock was perturbed by this, as he had a different definition of “getting Shinwell’s life straight,” one that preferably did not include Shinwell continuing to engage in gang activities.
He committed a crime by wiping the fingerprints and felt that he had some say in how Shinwell lived his life from there on out. In the middle of what may have been an argument, Joan was contacted by Detective Bell who wanted her, and only her, to meet him at the morgue.
She went and Bell wanted to know if she recognized the victim. When she insisted that she did not, he let her know that he had died of an overdose of medications which she had supposedly written the prescription for. Having stepped away from the medical field years ago, Joan of course knew she did not do it, but the DEA was not convinced.
Sitting with Sherlock and the Captain, they insisted to the DEA that she had not written any prescriptions they were investigating, but the DEA said she was still a suspect. As a result, they temporarily suspended Joan’s license, and she went to the pharmacy where it had been filled to look into the issue.
Sherlock, meanwhile, claimed he had a meeting and ended up approaching the detective that Joan had wanted to set Shinwell up with. The detective said he had an appointment with Shinwell but Sherlock told him to miss it, avoid the guy, don’t take him on. Sherlock believed that Shinwell would be a terrible informant and had a better chance of getting himself killed than helping anyone take down the gang.
As he tried to sabotage Shinwell, Joan convinced the pharmacist to show her the script and was able to track down the hospital her information was taken from. With that information they were led to Dr. Krieg, someone she had previously worked with, who appeared to be the one who stole her prescription pads.
They went to speak with her and found the doctor and someone who appeared to be a patient dead in her office. Whoever did it also took off with five boxes worth of prescription pads that had Joan’s information and that of other doctors. The Captain arrived to secure the scene while Joan and Sherlock went to talk to the victim’s family to try and figure out what her connection was to Dr. Krieg.
They met with her ex-husband and their son who appeared to be quite ill. He claimed to have some sort of autoimmune disease, among other things, and both insisted that the mother had nothing to do with the false prescriptions being written.
However, the son claimed that one time he was waiting in Dr. Krieg’s office when he saw a guy who was in bad shape, possibly in withdrawal from drugs. The doctor told him to leave but he was not happy about it, so he might be worth looking into as a suspect.
Shinwell, doing his gang related duties, went to some sort of money exchange but decided to ditch it partway through. A large, intimidating fellow had been following him throughout the city and he did not feel comfortable. He talked to one of his fellow SPK members and asked if he thought he was a cop, but the friend did not agree. He thought Shinwell was being paranoid.
Regardless, Shinwell did not pick up the money and instead hightailed it across town all the way to Sherlock. When he arrived and explained someone was following him, the man was waiting for him, and Sherlock explained it had been a test to see how quickly Shinwell would pick up on the tail. How was he supposed to be a good informant if he was followed so easily and without notice?
Back on the case, Sherlock and Joan were led to another incident where the same gun had been used. Apparently a gentleman had been shot with the weapon, and when they found him he admitted that he had been attempting to carjack a couple coming out of a furniture store. He was shot through the window.
They realized that Marla, the victim in Dr. Krieg’s office, had been the heir to some sort of furniture store empire, and Joan believed she was the intended target and Dr. Kreig had been an unfortunate bystander. The gun belonged to the ex-husband who admitted to the carjacking shooting (having covered it up because he was having an affair), but stated he would never kill Marla because of everything she did for their son Ethan.
They were not able to find the gun. Joan went to talk to Ethan to tell them their suspicion, but Ethan refused to even entertain the idea that his father would have killed his mother. It turned out Ethan was correct, and a pizza guy cleared his father with an alibi for the time and day of the killing.
Back to square one, Joan began looking for anything that could lead them to another suspect, and informed Sherlock that Shinwell met with the detective and was going to be officially registered as a CI. Before they could get into that discussion again Joan realized that Marla had been doctor shopping at the clinic which led her to believe that Ethan was not really sick.
It turned out Ethan’s mother was poisoning him for the attention and Dr. Krieg had told Ethan about her suspicions. Quickly the conclusion of the case came together and they looked at Ethan and found him through his accomplice (the previously mentioned drug addict from the waiting room).
In the interrogation room he told Joan she had to understand why he did it and she said what she did not understand was why he also killed Dr. Kreig who, despite her other criminal activities, was still a physician and did her duty to warn him about her suspicions. There’s no sympathy here.
The episode ended with a proposal from Sherlock to Shinwell. He brought the table from earlier to Shinwell’s apartment (which Shinwell interpreted as a rejection of his gift) and claimed that he knew about the previous offer Joan had made about teaching Shinwell to be a detective.
Since he refused that, Sherlock had a different proposal: they would spend time together and he would help Shinwell become a good informant. They would also play chess. Shinwell agreed, and it looked like the start of a friendship.
