OK, just trying to get my little brain around the Delorean turning up at Doc's lab, and how this fits into the timeline from the films. In the game, the Delorean has got the 'Mr Fusion' on top of it, and the licence plate from the future - but presumably it hasn't had the hover conversion yet. So do you think the explanation is this: After Doc gets to 2015 and he's adventuring on his own, he then takes a trip into the past (1931), before he goes back to Marty and Jennifer in 1985 and says 'You've got to come back with me ... " . He lands in jail in 1931 and the Delorean's homing device takes it back to Marty at the lab in 1986 - and that is where this game starts. This gives Doc the opportunity to have more adventures in time travel with Marty, and then when they're finished (in the game/s), he travels back to 2015 and completes the timeline of the film. What does everyone else think? I haven't yet completed this episode so apologies if the explanation is contained further on in the game!
