This has always bugged me: As we learned from BttF 1, Einstein going 1 minute into the future, he basically skips that one minute. While Doc and Marty await his return, Einstein doesn't exist and will not exist up until he re-appears 1 minute later.

When Marty and Doc go to the future in BttF II, Marty (and Jennifer) see their future selves. However, just like Einstein, both Marty and Jennifer were send to the future in 1985, and thus became missing from that point onward.

This means, they would see a 2015 where Marty, Doc and Jennifer have been missing for 30 years.

Is my logic sane or am I missing something?
