Jennifer Jane Parker McFly

"No, no, Doc. I just got here, OK? Jennifer's here. We're gonna take the new truck out for a spin."

"Well bring her along. This concerns her too."

Doc came to Marty and Jennifer and said he and Marty had to go to the future. Marty told Doc that Jennifer's there and they're about to go out on the new truck but Doc told him to bring her along because it concerns her too. Marty asks Doc what will happen to them in the future, worrying something bad will happen. Doc said that both Marty and Jennifer will be fine but it's their kids because something had to be done about their kids and they got on the time traveling car. Marty realizes that if Marty and Jennifer go back into the future, nobody would stay back and get married and have kids. Doc then pushes them off and told them to be good parents. Jennifer then watched as Doc backs up.
