Doc Brown: Ok future boy , tell me who's the President of the United States in 2025 ?

Marty : Donald Trump .

Doc Brown: Donald Trump? The guy from the Apprentice ?

The scene where Marty tells Doc that George punched out Biff…Doc is looking at all three siblings in the picture, says “Never?” to Marty. Marty says yeah why and Doc says nevermind. I feel like this was an odd encounter, like there was more to be revealed. Any insight?

Marty has a real problem thinking fourth-dimensionally.

But this guy seems to have problems understanding three dimensions.

so happy i finally found the hot wheels delorean after years of searching!

I wanted to see what you guys think about this because I don’t know the answer. Doc’s tombstone says “his beloved Clara,” but how did they even meet if she went over into the ravine and had only just recently arrived in Hill Valley?

I mean, was Doc just hanging out in the same spot where he and Marty were checking out the tracks, and he happened to save her? It seems plausible, I suppose. The only real explanation I have is that perhaps Doc’s presence in 1885 caused a subtle change—maybe the snakes that spooked the horses were in a different spot, or she took a different route that day.

Or maybe Doc, wanting a woman, had prior knowledge of the Clayton Ravine story and thought, Screw it; it won’t mess with the space-time continuum, and I need a woman.

WE'RE BACK BABY!

So I am thinking about signing up for the Fanhome DeLorean to celebrate the 40th anniversary this year but I want to hear from people who have done it before whether or not it’s worth it. Like I feel it’s one of those scams where they get you with the low prices for the first few packages then jack up the prices for the remaining ones or delay them intentionally. So is it something worth investing my time and money into or should I avoid it like the plague? Having a 1/8th scale DeLorean model seems like a dream too.

Forgive me if this has already been addressed, I did a fairly decent Google and Reddit search and couldn't find anything on this topic.

At one point in BTTF 2, Doc tells Marty that Jennifer can't come face to face with her future self. He theorized that they would either pass out from shock, or it could create a time paradox and destroy the universe, or just localized to the galaxy.

Later in the film, Doc is careful and avoids eye contact with his younger self as he helps him make adjustments to the Delorean.

But when Biff steals the time machine, he comes face to face with his younger self and nothing happens. They don't pass out and the universe, while altered, isn't destroyed.

Is this a plot hole, or was Doc's theory simply wrong?

Marty accidentally stops a random girl (who’s a French ancestor of his mother) from being executed while being chased through Paris by a French version of Biff and his gang and is arrested. While in prison and awaiting possible execution himself, he runs into Doc and they break out of prison. The prison itself just happens to be the Bastille on the day of the Storming. After watching the Estates General of 1789, Marty becomes sympathetic to the revolutionaries and joins their cause while Doc wants to get back to their own time before Marty disrupts history.
