Oh Gods, yes – he would be so angry. And I kind of want to see what Billy does when he realizes that he’s angry at Flint, sure, but he didn’t want him dead. Does he help? Does he use his knowledge of Naval practice to help Miranda and Gates, albeit somewhat reluctantly because whatever else he might be, Flint is part of Billy’s crew and arguably the man who saved him from slavery?  If Admiral Hennessy is involved, does he reluctantly condemn him, or does he turn a blind eye to help him escape (because I have complicated headcanon about Hennessy. So much complicated headcanon. Specifically, I don’t think he actually much cared about him being gay. I think he loved him like a son and did what he could to force him to leave London and get away from Alfred Hamilton, and said what he had to toward that end. Not that I think that excuses it, but I don’t think he’s as black and white as he looks at first glance, either.)
