Their emotional/moral weak spots
Emotional... She cares too much and wants good things for most people, even if she tries to be pragmatic and has some slightly skewed survival instincts.
Moral... She hates to admit it, but she would bend her own morals slightly in the pursuit of knowledge/information. And hate herself for it.
Being tied up, helplessness, drawing too much “attention” to herself, losing what morals and ethics she has
What-ifs/Alternate Timelines
Modern au Dani for her Fallout verse is that one kid who graduated high school at 15-16, due to skipping grades. She was the only girl in her high school auto shop class, and stared down anyone who tried to make a big deal out of it. Which wasn’t helped by the fact that she looked like a middle-schooler. She went to college and graduated young, with a degree in robotics engineering. However, due to her anxiety issues, and despite her tendency to be an over-achiever, she hasn’t been able to find a job of the sort her parents (Both members of SCIT’s staff, astrophysics department and engineering department, respectively) would want for her. She works as a freelance coder, and travels a bit in her old van,having had a few jobs helping out as a mechanic.
