Specifically, I have figured out where she stands relative to the other characters I'm currently playing.

Kaz, obviously, is at the bottom of the scale. She's 18 and has the partially-formed prefrontal cortex to prove it.

Then there's Vasanti. She doesn't NEED to exercise her impulse control very often, because she's built herself a life where the things she wants to pursue are the things she's allowed to pursue.

Most of the time, if she needs to exercise impulse control, she does okay (but suffers the whole time). Unless it's curiosity vs. personal safety -- then it's at best a 50-50 shot.

Top of the scale is Neastelyn Cadell. Half-elf child of knights who grew up in a delicate political situation. She knows her responsibilities, she takes them very seriously, and she's used to considering everything at least twice.

New character, a dwarven sniper, (name is Alvie Kelp until I think of something better) is about one notch above Kaz.

"When your job is so boring it tempts you to tip off security just to see what they'll do, it's time to either change careers or toss your comlink in the river until the urge fades. Replacing comlinks gets expensive after a while."

She's fine unless she gets bored -- in which case she has about twelve seconds of impulse control, which is just enough time to recognize the stupid impulse and cut it off with a different, slightly less stupid impulse.

I adore this.
