TNG: "Elementary, Dear Data" (s2e3)
LEAVE DATA ALONE! Dr. Pulaski teases Geordi for hoping Data would get into the spirit of cosplaying as Sherlock Holmes and Dr. Watson on the holodeck instead of quickly solving the case like a computer would. This compels Geordi to ask the computer to create a holographic adversary capable of defeating Data, a character who winds up being Sherlock Holmes' arch nemesis, Professor James Moriarty, played in this episode by the wonderful Daniel Davis.
Bryan and Kristen prepare for Star Trek: Picard - Season Three (debuts February 16, 2023) by rewatching this season two episode that introduces the Sir Arthur Conan Doyle character into the Star Trek universe. Speculation abounds in this one, but not what our hosts think Moriarty's role will be in this upcoming Picard season, but what they'd do if the holodeck existed in real life.
