Nicholas was the kid you were going to be babysitting. His father was a head inventer and had to go away however during the time he was gone he passed away due to an experiment that went wrong. You haven't met the kiddo. You walked in the house and saw a little boy no older than nine at the top of the stairwell with mechanical wings. He jumps and you catch him in concern as he giggles and says

"Dang it, another faulty test. Oh hello!"

oh god the kid is like his father. A scientist
