To me, there is a decided sense of Brandi-at-work here.
Brandi needs her agents to be balanced and predictable. When there is some trauma simmering júst below the surface, people get unpredictable.
"Unpredictable" in the sense that here is a danger that, said, trauma interferes with someone's behavior on an inconvenient moment.
In that case, a confrontational way of, well, "therapy" could very well purge it. No guarantee, but letting someone face what traumatized them, but in secure, relatively safe surrounding, hás a habit of straightening things out.
The way the several actors here get placed in situations where they get to sortof re-live the things that haunt them, but get a way out(!) offered too, reeks of manipulation to the umpteenth degree. Thusly (TP1+ CS1 ) x (TS2 + CoS ) + FC = PBT ergo: Typically the formulaic way Aspergers reason, if only to have sóme sense of controlling a situation. I.e. Brandi.
Where TP stands for Traumatic Past, CS for current situation, TS for Traumatic Situation, CoS for Controlled Situation and FC for Forced Confrontation. The PBT stands for "Purged Bottled Trauma"
Yes, it's fake mathematical gobbledigook, but one does nót study Philosophy without getting indoctrinated into trying to logically reason with the help of formula's.
Bottom-line: Something big is up. Brandi being Brandi, she will have already run various scenario's that cover the coming events, calculating in the fact that she already missed one artifact (the thingy Jin got stuffed up her sternum, what was it called?) of several she had placed around the world to keep the elder gods out.
Brandi is playing chess again, and needs the best of the best, and she needs them stable, predictable, having either worked through their trauma's, or having blossomed into their current titan/sub-titan state, so they can fulfill their respective roles in the coming game. If it works at all, is a secondary problem. Brandi cán be upended, but apparently Bud is the only one capable of that.(remember Bud's little trick to save Mayahuel?) hence my guess that Brandi is trying to weed-out uncertainty to an unmeasurable degree.
I could be wholly off to a place where no bus stops, but I strongly feel that all this exposition of the last months is a build-up to something rather large....
And The Library? Guess who is Brandi's Superior? Or, maybe, Brandi and The Library are working together closely as kind of co-CEO's
Who knows?
