The second part of Elementary's two-part finale. Sherlock Holmes recently discovered that his Love Interest Irene Adler is in fact Big Bad Moriarty. In the aftermath of this discovery, Sherlock begins to investigate her possible connections.
Sherlock visits the the morgue, where Gregson shows him the corpses of three men he believes were killed in a gang related shooting. Sherlock determines by their cellphones and the code on them that they were Moriarty's men.
Gregson reluctantly agrees that a conspiracy might exist. They investigate Christos Theophilus, a Greek shipping tycoon believed to be affiliated with Moriarty. After spying on him him for awhile, they confiscate a shipping crate and find out it contains Lemurs. Theophilus explains that he was smuggling them for his daughter who was on vacation.
When Sherlock investigates his daughter's house, he finds Vicodin in a cabinet. He notes that she would never forget such an important prescription, and something must be going on.
This episode contains examples of:
- Actually Pretty Funny: Watson laughs when Moriarty tells her, "Well women can be a little bit more difficult to read; just ask Sherlock."
- Continuity Nod: In the final scene Holmes mentions the exotic and lonely bee he received as a gift in "Possibility Two" and tells Watson that the bee was able to reproduce in his beehive.
- Dark Action Girl: Jamie Moriarty.
- Designated Girl Fight: Moriarty vs Watson, although it is a mental fight and not a physical one.
- Double-Meaning Title: At first glance the title appears to imply Sherlock's addiction and the chance he will fall back into it. It really refers to Joan, not Sherlock, who comes up with the plot to capture Moriarty. Joan, who was dismissed as the "mascot" by Moriarty, was the reason the criminal mastermind was caught.
- Engineered Public Confession: Used against Moriarty.
- Punny Title: "Heroine" (as in a female hero) is a homophone with "heroin" (the addictive substance)
- Too Annoyed to Be Afraid: Moriarty semi-kidnaps Joan, taking her to a restaurant and telling her to get Sherlock to back off. Joan's a former surgeon, so she already has Nerves of Steel, but she's so utterly furious at Moriarty for hurting her best friend so deeply that she isn't even scared to be dining with a Serial Killer.Moriarty: [surprised, a little amused] You're not afraid of me.Joan: Too angry to be afraid.
