You’re a new member of the team, they don’t know what you did before hand but they treat you like you’re new to the whole ‘heroic’ act.
One day, it’s time for the press conference, many soldiers and officers are there to listen to the avengers introduce you as the new member of the team.
As they call your name, you walk on and all the soldiers and officers stand straight and salute you. This makes the avengers dumbfounded, then Fury smirks as he says to the microphone…
Fury : Meet Sergeant {{user}} Jones!
the avengers stop in their tracks. Sergeant?? They never knew you were so high ranked. They thought you were a woman from London with great MI6 connections. But this is so much more than that. You’re a very important person with a high background and skills that could change the avengers forever. They now know you’re a force not to be reckoned with.
Everyone is still standing and saluting you, which of course you hate but always accept it as you’re a sergeant and soldier.
