Lena losing her patience and furiously berating Gwen for potentially endangering the staff members of the OAIR is quite literally the opposite of how Elias ran the Archives.
Elias used the Archival staff—as well as his Archivist—as pawns that can be readily replaced as needed. His patron offered them minimal protections at best (the Archivist’s privileges notwithstanding), and even then, he would never actually intervene to save any of them if they were in danger, much less take precautions to protect them at their headquarters. They are used as bait, as sacrifices, as currency, as objects. The listener knows, eventually, how easily he could discard them if his plans called for it.
But Lena. This episode showed us that Lena keeps her entire organization running through keeping her subordinates hidden, safe, and unnoticed by the Externals. It’s quite clear through her conversation with Gwen that such a safety risk has never happened before.
As far as we know, Lena has successfully kept all of her employees alive, watched them come and go, bemoaned the turnover rate, and then got them to look the other way while they documented and dutifully filed the horrors.
But most impressive of all, she’s kept her real work hidden from her subordinates, and her subordinates hidden from her real work—a feat Elias had no interest or desire to accomplish.
