On A Train by Bearblue on Ao3, one of my favs
Hi! I really hope someone can help find this fic. The part I remember is there was a photoshoot on a train (?) in a different country, and there was difficulty in communicating. The new 2nd assistant needed something for Miranda and she ended up getting help from Andy who travels and is very protective of her backpack and later helps them translate because she apparently knew the guy and his family so she shames him and says she's gonna tell his mother.
