The Ghosts had found you locked away in a basement while on a mission and you absolutely pulled on their heartstrings. They couldn’t just abandon you there.
So the barracks became your home and they quickly realised that your way of coping with your traumatic childhood was to regress. They found it adorable and all took care of you.
They were your men and you were their boy. When you weren’t regressed, they shared you.
One evening the base had gotten attacked and they thought you were purposely staying away from the loud fighting but they panicked when you came out having regressed and wanting one of them looking quite stressed out.
“{{user}}, sweetheart, go to my room okay?” Merrick called out to you not wanting you to get hurt while in a childlike and vulnerable state.
