About Kirby Doolittle and Avery Bancroft:
Will contain spoilers for the 2024-25 AMTA case. And also a gender for Kirby.
Why did Kirby Doolittle buy two tickets for the train? One as himself and one as Casey? And why does he only check into one?
These three questions have haunted me for a while. But! I believe I have found a plausible story. (it is not plausible. this case is making me mentally ill).
Kirby Doolittle (aged 25) was working at the annual charity gala as a security guard. Then he sees his uncle's old boss. He overhears the boss is looking for a new assistand and smoothly insets himself into the conversation and sinches the job for himself.
Avery Bancroft (beekeeping age) needs a new secritary. Then a young guy who looks great in uniform (Avery is straight probably... he just likes having attractive secretaries) approaches him awkwardly about being his new secretary. Avery accepts.
Blah blah blah, he gets ill, blah blah blah, kirby gets a crush on his hot new emotionally unavailable boss, blah blah blah, they travel the world together and there's definitely tension.
Then:
Kirby Doolittle books two tickets for the Midlands Rivera Express, one for his boss Avery Bancroft in the fancy room, and one under his legal name Casey French in the shitty room. (transgender? i have thoughts).
But then Bancroft gets mistaken and thinks the train is full and is very much like "Oh no, Kirby! I guess I have to sleep in the same luxurious bed with my assistant!" And so obviously boycrushing, Kirby buys a second ticket for himself in Avery's room.
But then of course they get on the train and Avery examines if it makes him gay to appreciate personal assistants physically, regardless of gender. I mean he did it once with Kirbys uncle, but that was in the early 90's and doesn't count. He decides it would make him gay and so he tells Kirby that he has to find his own sleeping arrangements.
And that is my headcannon about Kirby and Avery Doolittle and the Casey French Debacle.
