WARNING: This article contains SPOILERS for Star Trek: Picard season 3, episode 3, "Seventeen Seconds."
Star Trek: Picard season 3 has reintroduced the Klingon warrior Worf (Michael Dorn) in fantastic style, proving once again that the Son of Mogh is a foundational part of Star Trek. Worf spent seven seasons on Star Trek: The Next Generation and went on to star in the four motion pictures featuring the TNG cast. After TNG, Worf spent four seasons on Star Trek: Deep Space Nine, where his characterization became even more rich and fascinating, solidifying his position as Star Trek's greatest Klingon.
Worf's last canonical appearance before Picard season 3 was in Star Trek: Nemesis, the final TNG film that was released in 2002. After sitting out the first two seasons of Star Trek: Picard, Worf made his triumphant return at the end of the season 3 episode "Disengage," saving Raffi Musiker (Michelle Hurd) from a Ferengi gangster named Sneed (Aaron Stanford). Worf's appearance in that episode was brief but memorable, and the Worf of old would make a more robust, satisfying appearance in the next episode, "Seventeen Seconds."
