Hamilton and Jefferson start sleeping together.
They don’t want people to know, it’s not like they’re DATING, nothing has changed aside from some casual sex.
They get a little more comfortable as time goes, even become sorta friendly outside of work. Hamilton starts spending the night after shenanigans, keeps some of his clothes at Jefferson’s place.
One morning, in a rush to get dressed and get to work before he loses this great idea he has, Hamilton grabs a random tie.
What he doesn’t realize, is that he’s grabbed Jefferson’s favourite tie. Although Jefferson doesn’t really mind, (or even notice as he pulls the covers over his head, mumbling to Hamilton that it’s too early for his stupid, blatantly wrong ideas), those close to Jefferson at the office notice. Madison, especially, recognizes it immediately, and after a moment of shock, he sends Jefferson a flurry of questioning texts.
