Ronan tells the fitted sheet joke to Adam in the LA verse 😂
Henry is actually the one to make up the fitted sheet joke, with Adam specifically in mind. He texts it to Ronan as the latest in a long, long line of "shitty pickup lines for you to tell your boyfriend."
Ronan has never once validated any of these lines, because 1. he doesn't need to pick up his live-in boyfriend and 2. if he did need a pickup line he could come up with one for himself and it'd be at least half less dumb than anything Cheng ever came up with. Henry keeps sending him more and more ludicrous lines, because 1. it's called romance, Lynch, do you not want Adam to feel special, but more to the point 2. it really really annoys Ronan.
So Adam looks at Ronan's phone one day and sees an incoming message, zero context, just a dude hitting on his boyfriend, and with zero anger or jealousy at all he just says "huh. I could have sworn Cheng was more afraid of me than he was horny for you."
Ronan tries to explain, but he's hampered by the fact that he finds the entire thing very stupid, so he more or less just says "you're the fitted mattress" and goes off to sulk, which solidifies the whole moment in the Relationship Hall of Things I'm Never Going to Let You Live Down.
