That's what I thought, yes. 2015 Biff was a rich bastard. All the futures (and presents - 1985s) branched off from changes in 1955, so the "real" 2015 was one we never saw. Also the 1985 we saw at the end of BttF I may not be what they finally ended up with since there were further changes made in 1955.

Yeah, time stuff is brain-hurty.

IMO the best part of II was the clever insertion of extra action into I.
