In the camp, Saito addresses the enlisted men about a lack of progress in the bridge""s construction - there are only hree months remaining until the deadline.One of Alicia""s friends asserts that she brought him - he""s not a "party crasher." Embittered, Alicia discusses how she is a "marked woman" and followed constantly by police [an ironic statement since she will be followed for most of the film by government agents and the male lead silently sitting in her company]:I hate low, under-handed people like policemen, pussy-footing after you.When her life was threatened by being sucked into a giant fan, Batman arrived on a Batcycle and rescued her, while the Joker escaped.(Offscreen, he gave his own much younger counterpart a copy.) He then returned to 2015 before Marty and "Doc" realized what had happened.When "Doc" and Marty returned to 1985, they found the entire town of Hill Valley and world had changed for the worse, because the almanac allowed younger Biff after 1955 to "predict" racetrack results (his first big win was in 1958).
