Warning: SPOILERS For Star Trek: Picard Season 3The loss of the USS Enterprise-E while under the command of Captain Worf (Michael Dorn) confirms a warning from Star Trek: Deep Space Nine's Captain Benjamin Sisko (Avery Brooks). Prior to his promotion to Captain of the USS Enterprise-E, Worf served under two of Starfleet's greatest Captains, Benjamin Sisko and Captain Jean-Luc Picard (Patrick Stewart). Both men gave Worf valuable counsel and helped him find a place for himself that honored his Klingon heritage while respecting the rules and regulations of Starfleet. Starfleet's first Klingon rose up the ranks until he earned himself a red command uniform in DS9 season 4.
Worf got his first taste of command in Star Trek: Deep Space Nine season 4, episode 17, "Rules of Engagement", but it ended with him facing court-martial and extradition to the Klingon Empire. Captain Sisko successfully defended Worf against the charges of destroying a Klingon freighter and killing over 400 civilians by proving the accusations to be false. Despite this valuable lesson, and a warning from Sisko, it's clear that there was still much to learn about command when Worf succeeded Picard as Captain of the Enterprise.
