Character error

In the opening heist, the getaway involves dumping the original car and switching to another. However, while Buddy, Darling and Griff all wear gloves, Baby does not. During his "dance" scene he touches, and leaves fingerprints on, the steering wheel, wiper control, the outside of the door, and a water bottle (which he leaves in the car). During the getaway he also would have left prints on the gearshift and the interior door handle.
