Warning: SPOILERS for Star Trek: Picard Season 1, Episode 9.
Romulan Bird-of-Prey similar to the one Captain James T. Kirk (William Shatner)'s U.S.S. Enterprise fought in TOS also appeared.
In Star Trek: Picard episode 9, Jean-Luc Picard and his motley crew aboard the starship La Sirena brought Starfleet's history of exploring the final frontier, the crew of Kirk's Starship Enterprise already had fateful encounters which those very things.
Raffi's "angry reptiloids" remark is likely a reference to the Gorn, one of Star Trek: Deep Space Nine crew time-traveled back to the 23rd century. Of course, Star Trek: Picard's heroes met another reptiloid, a Beta Annari named Mr. Vup, on Freecloud so he might be the one on Raffi's mind instead of the Gorn.
The "homicidal fungi" Raffi mentioned is a deeper cut and it could be a reference to the Star Trek TOS episode "The Conscience of the King". When Kirk was a teenager, he lived on a colony on Tarsus IV, which had its food supply destroyed by exotic fungi. The governor, Kodos, made a horrific decision to put half of the colony's population to death to save the lives of the other half. Years later, aboard the Enterprise, Kirk met Kodos again; the governor was now posing as an actor named Anton Karidian (Arnold Moss) and his daughter Lenore (Barbara Anderson) systematically murdered everyone who could identify her father as Kodos.
Star Trek: Picard's TOS references also have some thematic resonance with episode 9's story. Despite Narek (Harry Treadaway), her abusive Romulan ex-lover, she decided to spare his life, which she came to regret. It flips the switch on Kirk's heroic act of mercy because Soji's choice ended up getting her synthetic sister Saga (Nikita Ramsey) killed when Narek escaped, bringing Soji one step closer to becoming the Romulans' Destroyer.
In "The Conscience of the King", Governor Kodos sacrificed half of Tarsus IV's people to save the other half. This echoes Sutra's desire to call upon an ancient federation of androids from beyond the galaxy to wipe out the Romulans and all organic life because she values synthetic life above all. But in Star Trek: Picard, the galactic armageddon posed by the synthetics federation is a far greater threat than any angry reptiloid or homicidal fungi.
Star Trek: Picard streams Thursdays on CBS All-Access and Fridays internationally on Amazon Prime Video.
