My MC has a critical flaw of Investigation.
I hadn’t thought about this before, but a gist on Subtext suggests being interrogated.
( BTW, she also sticks her nose where it’s not allowed, thus bringing trouble of a different sort but that is more due to the OS story inhibiting her.)
But, having already written most scenes a while back, I see now that in every Act, she is being interrogated by someone. And, she always breaks out in a cold sweat, starts fumbling - all making her look suspicious as hell (of course she’s innocent).
