I was jist pointing out that she, like her sister, has an indefinable little something extra.
If you want to reduce it to game terms, with her maxed out etiquette and con pools, shes rocking an 8 to seduction and an 8 to shadowrunner etiquette. Plus glamours makes 9, CHA 7 makes sixteen, clothing makes 17 and her vomeronasal organ makes 18. So with the maximum oenalty she still has an 11. Average human dice pool is about 5. So if we strip the modifiers out thag would make her the same pool as a relatively socially adept uni student (4) who is also the absolute pinnacle of natural beauty (7). Think a super sweet, super pretty college freshman. If not super biased, then the number only goes up.
Of course, by that dead reckoning Goodnight's dice pool of 24 should allow her to talk her way out of literally anything just by body language and a smile.
And in terms of grace, her AGI is 13 and her gymnastics(dance) is 8, plus three ranks of improved ability. Outside of the high sidhe, her movements are about as graceful as they come.
