How did he get back to his original 2015 where Doc and Marty were? I've read theories but that hole has not been plugged in my mind.
if you accept the BS about Jennifer and Einstein just getting folded into the original Timeline when they fixed it in 1955 i guess the same could be true for Doc & Marty. when the future got changed to the future of Evil HV it changed around them and they didn't notice, however old Biff just vanishing yet his cane topper remaining has always been something i could never really rationalize. i've seen theories of he was able to travel to the future but since that version of him no longer existed he disappeared, but that doesn't jive with what we saw happening to Matry in 1955.....so i just don't know time travel is confusing!
