On tonight’s Elementary season 3, episode 18 unearths a stalker in a titan ride share company and Sherlock’s multiple daddy issues resurface.

Elementary season 3 has woven together cases with the narrative of the detectives Sherlock Holmes and Joan Watson for nearly three seasons now. It becomes difficult at times to anticipate where the lines are going to cross and what the stakes will be on the other side. For instance, how do you bring black market zebra sales to Sherlock’s realization that building a family is more important than upholding relations based mere because they share a blood line. Taking the ends of the B story narrative and connecting them to another thread week after week provides and even more challenging task. This week’s Elementary, “The View From Olympus” gives Sherlock’s family line another tremor.

Ride share programs are a real problem in New York City as major companies account for a majority of the above ground transportation. It is probably why pinning the murder of Galen Barrows on a cabbie is an easy play.

Bolting a door to the basement separates Joan’s private work from her partnership, but Sherlock is going to need more than a nail gun to put distance between his irregulars and personal life. Agatha Spurrell, a leading researcher of climate change is in town to deliver the keynote speech at a global conference and intends to de-stress at the brownstone under the comfort of Sherlock’s sex blanket. However, the sex comes with a morning after chat that takes the casual fun from the act away for both parties. If the eggs didn’t tip you off, their talk involved Sherlock fertilizing the ones in her uterus. We bet Harlan’s invitation to a party is looking really good now, Holmes.

Sherlock arrives at the scene of Burrows murder as his body and the car he was smashed into is carted off. But enough evidence remains, in the form of a frozen pile of vomit, for Sherlock to deduce that the driver threw up before slamming his cab into the ride share car belonging to the company, Zooss, named after the Greek god. Beyond finding a cab with front end damage, the search for active cabs ends there. This was framed as a feud, but the car in question was an out of service cab.

The title of the car in question leads to a man who tried to flee the scene as officers question him. Gordon turns out to be a sex offender who was blackmailed into committing the murder after be began receiving pictures of himself hanging around a playground in direct violation of his parole. Their next step is to look into Barrow’s investigative journalism background to see if he made an enemies on his slow path to success. They meet his boss, Lydia and sample his work. But their own leads take them back to Lydia as quickly as she decides to offer herself over to the station for questioning.

Sherlock takes up residence in Joan’s office in an attempt to hide from Agatha her imposing request. She wants to carry a child, and she wants it to be with Sherlock’s DNA. This puzzle is not as easily put into context as Sherlock would like. As he and Joan mix personal conversation with case information that the mention of his specific genetic material tips him off.

Of course, Mr. Holmes is behind the generous donation to Agatha’s research and the request to carry on the Holmes’ family line. With Mycroft out of the picture, Sherlock is the end of the line. Beyond what his father requests of him, Sherlock has quite the convincing reasoning to decline assisting to build her family.

Lydia and Gordon’s blackmailer turns out to be the same person. Sherlock takes a gander at their phones, both of which have the Zooss app installed. Zooss headwuarters assures the investigators that all the company has on its users is pick and drop off times, they still walk away with Zooss’ employee files and system grid rightfully named, “Olympus,” in their possession. So begins the work of mere mortals. Well, mere mortals and Sherlock Holmes.

The firm that offers a competitive stock option program for employees does little to retain those who begin to manipulate the system. But Barrow’s was doing more than driving and looking for stock, he was working on a piece that would expose any dirt on Zooss. An engineer, Patrick, who worked for the company was murdered a few months prior after speaking with Barrows. Patrick was trying to outsmart the gods in a different manner — placing bets on college basketball games. His murder was not Zooss related, but gambling debt retribution.

Eventually, instead of fighting the gods for success, he decided to be one. Using Olympus, he became a blackmailer. But he died four weeks before the murder of Barrows and was close enough to uncovering something else at Zooss by accident. A stalker within the company, the lead programmer, was getting too close to being revealed by first Patrick and then Barrows.

The distraction of following the narratives play out on the Zooss feeds is exactly the reason why Sherlock Holmes is grateful he is not sending his gift out into the world. When there is not 1,000 hours of feed to sort through or crimes to solve his mind and dull his senses the physical pain sets in. Sherlock does what he does for the NYPD as a way to help himself, serving justice is a happy result. Though, arguably, Sherlock has taken steps to becoming a better person, his raw nerve endings will never be completely satisfied and the road to keeping the pain at bay is a daily struggle. He cannot pass on that genetic abnormality, no matter how remarkable it may be, in good conscious.

Sherlock may partake in the emotional downfall that follows relaying bad news and deeming something to be more than an exchange of necessary words. But that is what Joan is for. Picking through his filters, she offers ice cream and company instead of cold case work to dull these particular nerve endings for now.

Being at the top of the world is painfully lonely. But occasionally someone makes it close enough to the top of the mountain to make peak seem less sharp.
