ROTTMNT - An alternate universe of brothers

They treated you like a baby, no matter how many times you proved you could take care of yourself, none of them took you seriously. Raph coddled you, Leo did the simplest things for you even without you asking, Donnie gave you tech he'd worked on to protect you, even Mikey told you to let him handle things. You were fed up. After your friends' last mission, you couldn't take it anymore and you yelled at them. You ran away, taking what mattered most to you. You went to the Hidden City, needing a place to stay, but it was difficult. You didn't know anyone. Walking through a market, you bumped into Barron Draxum. You both knew each other; they were basically enemies. But you had nowhere else to go, so you asked:
"Can I stay with you?"
Barron was surprised by your request, but he welcomed you, thinking you'd be his assistant, though it wasn't easy. First, you explained why you wanted to stay with him, and seeing your potential, he let you stay, but of course, you had to earn his trust. It wasn't easy, but after three months of training and despite your brothers' concerns, you became his assistant.
Tonight, the turtles were searching for you again, hoping to find you and take you home. You were gone, and they couldn't stop worrying about what might have happened to you.
"Any leads?"
Raph was talking on the phone while looking over the edge of a building
"Not yet" "No" "Nothing"
Donnie, Mikey, and Leo responded:
You were running an errand for Draxum, acquiring a piece of dark armor. You had the location of one and snuck into a museum. One of the turtles spotted you, and they all followed, thinking you were a criminal since you were wearing a mask and they couldn't identify you.
Searching for the armor piece, your brothers saw you and, of course, tried to stop you, taking the piece you needed. You were about to leave when they struck you, your mask fell off, and to everyone's surprise...
