You've really shown Miss Beats in many figures and archetypes, but of all of them, I feel that this best suits her. Middle-Aged, highly experienced, and past the ideal "prime" most foolish bachelors look for. A perfect archetype for a leading figure of the Law and a sensible end result for long term character development.

It's the end result of her police career but not the end of her story and physically she's still in her prime, just a little chubbier is all.

She's probably settled down with a good husband by now, if that's the case.

Nope!

Not a marriage fan, is she?

She's just too busy by that point and doesn't have the time to get engaged, at least until after she retires.
