Why didn't Old Biff come back to an alternate 2015?

[Tom]

Maybe there was an original timeline where Marty and Doc (with Jennifer) come back to the to the Delorian to find it missing! This leads them to an small adventure to find who stole the Delorian and get it back. They finally track Old Biff down but its to late he goes back to 1955. Before this happens Old Biff tricks Old (47 year old) Marty into telling him how the car works, he promises old marty that he would take him back to he day of the Rolls Royce accident. Since Old Marty just lost his job he accepts but Old Biff tricks Old Marty and takes off with out him. Old biff then decides to prevent anymore trouble he would just return the car to the same date and time he stole it to prevent anyone from getting suspicious.

I've always assumed that at some point in the future, Future Doc and Clara went back to 1885 to deliver a time train to Past Doc and Clara!

Or if that seems too much like cheating, maybe he just delivered a flux capacitor and some key components that Past Doc couldn't build, to help him finish it.

Speaking of which, i find it amusing that there are 4 different Delorians in 1955!

- The original Delorian from the first movie
- The Delorian Doc and Marty cam back to 1955 with
- The Delorian old Biff came back with.
- the 70 year old Delorian in the Mine.

Plus the raw materials used to build the Delorean that were actually native to 1955. So actually, those same atoms coexist at 5 different points in space at that time.[/QUOTE]

Maybe that is why that date is a 'temporal nexus" of sorts because of the overlaped time travel. lol

If the Grim Reaper ever came to take away Doc or Marty in 1955, he'd be awfully confused.

It's pretty simple, the Doc had the knowledge to make everything he needed in 1885. If there were componets that were synthetic he knew how to create them as well. and various manufacturing proccesses. All the Doc needed was time (maybe years) and he had that. By showing up with 2 sons it kinda indicated that it took him 5, 6, 7 or more years to get the Train done.

-Left over parts from converting the Delorean to train pushing mode

-Plus a 2015 hoverboard with hovering components

Doc probably went back to pick up the mangled train parts too

Ummm.... There wouldn't be any. Put the car in neutral, change the tires with the rail wheels. Boom. Done. No leftover parts.

The Fuel Injection manfold that blew off but that just metal not no big thing there.

It's likely, not wanting to pollute the timeline, Doc would've put the blown manifold into the DeLorean before they departed.

Though this does beg the question why he didn't "cover his tracks" in other ways by, say, burning down his barn/cleaning it up and one also wonders what happened to Hill Valley's original blacksmith?

Can I ask a question about Part II totally unrelated to the OP?

I can? Cool.

Why would Doc and Marty have to go into the future to fix a mistake that hasn't happened yet? Once they travel back to 1985, wouldn't they have to fix that mistake again once the actual year rolls around? Or better yet, just tell Marty in 1985 what happens in 2015 that way the trip wasn't necessary?

I know why; because we wouldn't have a movie without it, but as far as I'm concerned, I'm cool with that!

Yeah, it's illogical but Zemeckis was pretty much "trapped" into doing a future story about Marty's kids because of the ending coda (written without any intent of doing a sequel.)

But in "reality" Doc could've just told Marty to raise his kids better/not get in the accident that'll destroy his life.

The way BTTF's time-travel logic works Marty won't have to worry about the mistake "needing fixed again" even if his future continues to progress exactly the same, no more so than George reverted back to his passive ways after Marty left 1955. We could reason that he couldn't simply tell his kid not do it later in the future because of the whole "kids don't listen to their parents" thing.

I think also recall from the novelization of the movie Marty Jr. wanting to talk to Marty Sr. (this is seen by Jeniffer as she's in the future M.McFly home) but Junior being shrugged off or simply told "later son" by his dad. Thus implying that if Marty was a more attentive father Marty Jr. wouldn't have been a part of the robbery. (Keep in mind the "real" Marty Jr. would have no idea what happened with Griff and likely still would've tried to meet-up with Griff, obviously wouldn't have been able to, and the robbery wouldn't take place.)

But all of this is moot because now due to Marty not being in the accident his future is going to be very different and it's entirely possible Marty Junior (at least the one we meet in the movie) won't exist. And no Marty won't become a rock-star. He might become more active in other aspects of the music industry or simply just be a more aggressive or confident person less prone to pressure and being goaded into things but I do not accept that Marty's "destiny" or "future" is to become a rock star. If it is, he's better off with the 2015 future we see than one that leaves him an unintelligible old-man with collapsed veins and a death due to heroin abuse.

Rather than make another thread, I went back to relive the trilogy on my 2002 dvd releases. It has come to my attention that Biff is irredeemable.

First movie

-He tries to con George into thinking he started the second wax of Georges car.

Second movie

-After getting decked by George, Biff still wants to run over Marty for stealing his book.

-Here's the big one. 2015 Old Biff stealing the delorean and altering his past. Old Biff had nothing to provoke him to be this devious.

Third movie

- Near the end Biff says his trademark line "Hey butthead" He didn't mean to say it to Marty but his anger is still lying underneath

 

[Silvercrest]

Nope, Biff was never supposed to be redeemed or see the light. He was just put in his place so he'd stop bothering George. Probably kept on bullying everyone else.

Heck, he shot George in the alternate 1985 timeline, and George had still punched him out in that timeline!

 

[Admiral_Young]

I agree that the reason for them going into the future in the first place is somewhat ridiculous. I suppose that Doc felt some responsibility for Marty and knew that by using the time machine that the two of them could correct the incident. It would be interesting to see if the changed 2015 made Marty Jr any different? Probably not, he was kind of a douche wasn't he?

 

[Snaploud]

I suppose one could argue that Doc was using time-travel to subtly teach Marty not to mess up his life so much, but it's a little bit of a stretch. One could hope that Doc planned to at least engage with Marty a bit more post-accident, though (perhaps even send him to the far future for a cure).

 

[Admiral_Young]

Also I saw it as Doc taking up Marty's request to look him up...Doc obviously did and discovered that his family turned out to be a mess.
