Anyways! By a similar token, Carissa Sevar has sometimes been known to undergo great cognitive shifts when under importantly different cognitive conditions. Perhaps at INT 29 she will decide she is a different person not bound by past paths. Perhaps at INT 29 she can configure her thoughts in a way that sidesteps the geas earring without that ever looking on a first step like a forbidden intent to defeat the geas.
It would take both Intelligence and arrogance to imagine you'd come up with a plan to defeat that possibility at INT 27. It would require respecting your own INT 27 but not her INT 29; it requires thinking that you exhaustively searched every option Carissa Sevar could see.
You could call the alternative Wisdom, but in dath ilan they'd just call it thinkoomph or maybe security mindset.
