If they really are minor differences, then multireplace is great.
Like, if your base exchange is:
Y opens the door for you as your approach the cafe. "Fancy seeing you here," he says.
You gesture to the menu. "I'm addicted to their maple latte."
"Come here daily then?" Y asks, slipping in line behind you.
"Seems like it."
"I'll have to try that latte then. Can't pass on an expert opinion."
Then you could write that using multireplace to make Y more suspicious.

What’s fun is that you can then write the same bit taking multiple world states in consideration. For example, Y being suspicious is one. But maybe earlier you asked the MC for their favorite latte flavor. Or maybe, the MC owns the cafe or not.
*comment cafe_own: 1 is MC owns it; 2 is someone else own it.

…basically, I adore multireplace.
