The gruff Scottish-accented Emergency Engineering Hologram of La Sirena, one of five copies of Cristobal Rios, who takes part in Raffi's group interrogation of the ship's holograms in 2399.
Ian is the engineering programme among the emergency holograms of the freighter La Sirena. Like Emil, Enoch, Emmet and Mr. Hospitality he wears the face of Cristobal Rios and is played by Santiago Cabrera, in his case with a broad Scottish accent in the tradition of Starfleet engineers.
He features chiefly in the first-season Picard episode Broken Pieces. When Rios shuts himself in his quarters after seeing Soji, Raffi summons all five holograms at once to ask what happened aboard the ibn Majid. Ian is blunt and impatient with his fellow programmes but has the same gap in his records as the rest.
Between them the holograms supply enough fragments for Raffi to confront Rios, who finally tells the story of Captain Vandermeer and the two synthetic envoys.
