Warning: SPOILERS for Star Trek: Picard Season 3, Episode 4 – "No Win Scenario"
In Star Trek: Picard season 3, episode 4, "No Win Scenario," Captain Liam Shaw (Todd Stashwick) answers the decades-old mystery of why the Borg named Jean-Luc Picard (Patrick Stewart) 'Locutus of Borg' when they assimilated him in Star Trek: The Next Generation. Picard's brief time was the 'spokesman' of the Borg Collective has haunted him ever since. Jean-Luc has defeated the Borg time and again, yet the trauma of being turned into Locutus, and the shame of the blood on his hands, remain part of Picard's psyche.
Captain Shaw interrupted Admiral Picard's bonding time with his son, Jack Crusher (Ed Speleers), in Star Trek: Picard season 3, episode 4. Shaw bellied up to the bar of the USS Titan-A's holodeck recreation of 10 Forward and revealed exactly why he hates Picard: Shaw is one of the few survivors of TNG's Battle of Wolf 359. An engineer aboard the USS Constance, Shaw was randomly chosen to live as the Borg, led by Locutus, massacred 40 Federation starships and murdered 11,000 Starfleet Officers. Shaw's riveting monologue was pointed squarely at Picard, the reclaimed, ex-Borg, who he blames for all of those deaths and the trauma Liam has lived with since.
