I'm awestruck by the economy of writing and elegance with which you wrapped up this tale.
We got to see Avery finally accepting the family relationship with Bill and Anna, and realizing that they really do care for him (which no doubt contributes to his ease with himself and his ability to grow into a good, secure adulthood).
Joseph's police comrades are perfectly accepting of his gayness and his wedding to Orson. O, sunny day, indeed!
Harlan gets to show that he's a good person at heart, despite his mobster origins, through his help to Lee. And that it's a recommendation for an acquaintance like an ordinary person, rather than an enforceable order, came through.
And Lee and Avery have both matured, showing themselves capable of an independent life, and they are set up for a realistic continued relationship, even perhaps the hint of a possible (though not proven) happy-ever-after ending.
