The brief case full of Mutiple time line currency really proves,Doc Brown time hopped and knew more than he let on. Take a serious look at the case it has money from 19xx A and 19xx B maybe even more..

There's no need to fix Cole at all really.. That fight with the Goro like character could been a fight with a body double for the Prince of the Shokan.. The MK world has shown this trickery with the former king of Outworld Jerrod he had many doubles. The real problem is\would be Kano coming back that guy has never used a body double ..unless they're doing that muti-verse story stuff, No thanks then.
