Star Trek Picard: Every Easter Egg & Hidden Reference From 'Et In Arcadia Ego, Part 2'

Picard awakens in his new golem body and is assured by Agnes, Soji, and Soong that it's basically identical to his old, 94 year-old bod, with no augmentation or immortality. This confirms that Picard is actually 15 years older than Patrick Stewart, as established by Picard's service record in TNG's "Conundrum", which gave his birthdate as 2305.

The four hold a makeshift vigil and remove the isolinear chips that control the simulation that houses Data's consciousness as Picard quotes from Shakespeare's "The Tempest". Fittingly, Data once performed "The Tempest" under Picard's guidance in the TNG episode "Emergence".

In the simulation, Data is now dressed in a smoking jacket, enjoying a glass of brandy, and listening to "Blue Skies" as sung by his "daughter" Isa Briones aka Soji. "Blue Skies" is the same song Data performed at Riker and Troi's wedding in Star Trek Nemesis. B4 later hummed the song at the end of Nemesis, indicating that some part of Data's memory engrams lived on.

With a manifestation of Picard dressed in his old TNG uniform by his side, Data rapidly ages and finally dies. The end of Data's journey from "Encounter at Farpoint" to Star Trek Nemesis to Star Trek: Picard. The end of an era.
