Star Trek Picard: Every Easter Egg & Hidden Reference From 'The End Is The Beginning'

Raffi gives Picard the number of another ex-Starfleet officer with demons (there's three in this show so far): Cristóbal Rios, captain of the unregistered civilian ship La Sirena.

Rios is being treated by an EMH who looks exactly like him, but with a British accent and a shirt. EMHs (Emergency Medical Holograms) were first established in Star Trek: Voyager and that show's doctor, The Doctor. The Doctor (played by Robert Picardo) later expanded his program to include acting as an ECH, Emergency Command Hologram, so the appearance of La Sirena's other Rios hologram, the Emergency Navigational Hologram is a natural evolution of that.

The EMH removes a the giant piece of tritanium shrapnel from Rios' shoulder, an ore used in starship construction, first established in the TOS episode "Obsession". Rios' other shoulder has a tattoo of a mermaid, which is appropriate since the name of his ship, La Sirena, means mermaid in Spanish. The med kit the EMH uses to treat Rios has the traditional Starfleet Medical caduceus on it, it was first seen in Star Trek: The Motion Picture and cropped up in almost every instance where a medical symbol was required throughout the franchise.

The La Sirena herself is a new design to Trek. The captain's chair, however, resembles the chair seen aboard Defiant-class starships like the USS Defiant in Star Trek: Deep Space Nine and Star Trek: First Contact. Rios' ship is also lousy with orange holographic displays, which according to the DS9 episode "The Visitor" replaced the traditional, backlit graphic interfaces commonly used in the Next Generation era.

Rio's Irish ENH recites a few of Picard's achievements: Chief contact with the Q Continuum (see "Encounter at Farpoint", Arbiter of Succession ("Reunion"), savior of Earth from Borg invasion (plural, "The Best of Both Worlds, Parts I & II", Star Trek: First Contact), Captain of the Enterprises D and E (obvious), worked alongside the great Spock ("Reunification, Part II").

The La Sirena's Captain Rios is seen reading "Tragic Sense Of Life", by Miguel de Unamuno, which is... on the nose.
