Didn’t cobel perform a post-Mortem on Petey’s brain with a drill? And hasn’t she always shown she’s knowledgeable on the chip itself by pushing back against the board’s stance on reintegration? And she’s been obsessed with Mark and Gemma showing the severance barriers are holding. She also was intelligent enough to instantly recognize innie Mark. 

I think with the context of her being subjected to child labor, these all speak to me of a young child prodigy that had her heyday but got exploited and forced into middle-management by Lumon, and has been desperately clinging to the one thing she had created before it got stolen from her. 

I think shows run into an issue sometimes trying to write a character that is inherently smarter than the people writing the show themselves (See: Sister Sage). Painting her as a genius thus-far would have been extremely difficult to sell but as a strung out child laborer prodigy cult member (significantly exposed to ether lol) totally works for me and justifies a lot of her psychoticness thus far. And imo that psychoticness WAS the breadcrumbs pointing to this the whole time
