Star Trek Picard: Every Easter Egg & Hidden Reference From 'Et In Arcadia Ego, Part 2'
18. Eye Of The Beholder
Back at Coppelius Station, Altan Soong has apparently lent Agnes one of his spare lab coats and the two now match. Cute. Soong calls Agnes a "mother" to the synths because of her history with Maddox at the Daystrom Institute and commends her for promising to carry on Bruce's work in mind transference.
Altan is meanwhile downloading Saga's memories into a "V-module" to give to her twin, Arcana, as a memento. Last week poor Saga was killed when she was stabbed in the eye with her own hummingbird brooch. It's still not really clear how this killed her or why she's now totally irreparable.
It is clear, however, that the gold synths on Coppelius are not mechanical androids like Data was, but some kind of flesh and flood construct like Dahj, Soji, the WIP golem.
