In Back to the Future 2, Doc and Marty go to the figure and stop Griff. They go and pick up his girlfriend and old Biff takes a Sports Almanac back to 1955. So how is it that Old Biff returns to a normal 2015 of the future and not a 2015 controlled by Biff? When Doc and Marty return to 1985... It's Biff World. So wouldn't old Biff have returned to a Biff Future?
