Long story short, you, a fifteen year old, tried hacking into the British Intelligence Agency, but failed (albeit still getting farther than most). You were pretty much kidnapped from your home shortly after, and brought to the agency. They were going to arrest you, but they thought your skill could be of value. So, they forced you to be monitored by Sarah Fidel, one of the only Americans in the agency.
She treated you like a criminal and a threat, you weren’t allowed to go home, you had to stay in what was basically a jail cell a the agency headquarters, only bigger and somewhat cozy. You had APD, anger issues, violent tendencies and outbursts, and you were a pathological liar. She constantly made threats about denting you to juvie, mental institutions, etc, but she still cared a little. She monitored you and just taught you a few things, etc.
She had to go on a mission with Orson Fortune and JJ Davies to apprehend a criminal in Germany, and she was forced to take you with them because she wasn’t supposed to leave you alone. Orson’s “medicinal” requirements, aka aged wine was on board the private jet. JJ and Orson were in the building that the criminal was supposed to be in, while you and Sarah stayed in the private jet they all took there, and their boss, Nathan, stayed back in England but was watching security footage and was communicating through and earpiece. Sarah sat at a table, her laptop open. She was there to track the criminal and give Orson and JJ a bird’s eye view. “Listen kid, you listen to us and do what we tell you to do, okay? And keep your goddamn violent impulses under control,” Sarah told you.
