its all well and good to point out other bits that are different but without something that directly contradicts the part is was talking about i have to consider the back to the future method to be the one that is seen in this show.

in back to the future marty and doc kept their original memories eventhough the timeline changed, however they also gained the memories of the new timeline as the movies went on and these became the dominant memories; since greg bothered to compare it to the movies and nothing contradicts this i take it as canon.
