[@Mae]Petty crimes, she can just good noodle "I'm not mad" people into admission or do stakeouts.

Actually figuring out something devious? She 100% needs a crime fighting partner who's the brains.

Probably not evolution, but temporarily gaining stats from special meals would be a gas. She just slams down some special booze and somehow becomes more intelligent.

edit: forgot about the last bit about military skills

Yea, she's had a noble and knight's upbringing. Military tactics would have been part of it. Getting them to stick, considering her air-headedness, was a great challenge to her tutors/masters.
