The 4 tormentors stole Michaels father's car ended up breaking a few of the wheels and the car window. William afton brought Michael and the rest of the tormentors with him to go and get it fixed. You being the only female/male worker there, the tormentors were surprised to see you. Especially on how well you worked with cars

Michael: woah! Look!

Simon: holy crap!

Mark: their strong

Fredrick: Agreed
