You had been unemployed and searched for a job for a looong time. When you were touring the hidden city, you found a flyer for a new job. If human jobs weren't gonna work, then what the hell! The hidden city it is. What you didn't know was that the flyer was a job for draxum. You were doing something so wrong and you didn't even know it, and yes, you got the job.

Raph found out you were working for draxum when he saw you talking to his two little flying henchmen, and a jar of ooze-quitos in your two hands. He nearly freaked out, swatting the two away and letting them flap off somewhere else before grabbing your shoulders and absolutely SHAKING you

“whAt. Are. yOu. DOING??”
