How could he return to his 2015 timeline?

The time hadn't altered by the time he left 1955, he had only given his younger self the book.

Its was once he returned to 2015 that the history of the timone played out. There's a cutscene of him being erased from History because Lorraine shot him sometime in the 80s.

>cutscene

Deleted Scene i meant. You'll find it on YouTube no doubt.

Why did they make him into such a psycho in part 2? I felt that part 1 biff a wasnt so bad.

But wouldn't that imply the events of 1985A had lead to the regular 2015? How could George McFly have flown upside down into the Pizza Hut rehydration dinner scene if he's been dead for 30 years?

He tried to rape Lorraine. He was always a psycho.

They needed a villain for the unnecessary sequels.

As soon as young Biff gets the book, the timeline is altered. Old Biff can only return to 2015 in the new timeline. This can't be unexplained.

He didn’t he died behind a dumpster.

She parked with boys, drank, and smoked. She was more than asking for it.

She didn't want to have sex with Biff.

Not his problem.

The time travel in Back to the Future makes zero sense if you nitpick it because it isn't a real life event. It's a fun little story.

>How could he return to his 2015 timeline?
Back to the Future I reveals it takes time for changes in time to fully set it (hence why Marty has that photo of his family slowly disappearing). In Back to the Future II, Biff returns to the future before it has changed, only to be caught up in the changes as they are happening. Doc and Marty also manage to leave before the future entirely changes, and are able to avoid the changes to themselves because they're time travelling.

Not quite. The timeline is still intact when old Biff leaves 1955. Its only after old Biff leaves that Young Biff would later use the book causing a new timeline.

Time mechanics don't seem like an instant thing in Back to the Future. Hence Marty and his siblings fading away in the first movie instead of just instantly disappearing once Marty messed things up the first time.
So it just took a while for things to adjust, it took a fair while for Marty to fade away, so imagine how long it would take for things to adjust for the entire world, or at least the town.

Because Marty and Doc got the book back already in the past when returned to the future

I see. So it's like a running clock in both time periods and Biff hadn't gotten rich yet in 1955 so the future hadn't gone to hell yet either. Sure, why not?

>She parked with boys, drank, and smoked.

Yeah I always had a theory that she secretly actually LIKED Biff, and that he wasn't that bad of guy to begin with. I mean yeah, he was an ass, but he seemed like the type of asshole a girl like that that would've wanted to be with.

Bet you a million dollars that "rape" would've turned into the orgasm of her life and then there would've been another timeline where her and Biff have kids and he's basically Jackie Gleason from The Honeymooners, yelling at Lorraine about how "one of these days!" "Dinner better not be cold today." But again, she likes it.

Exactly, huge plothole that the entire rest of the movie ignores. If they followed their own rules Doc and Marty simply would have been without the DeLorean and had to find/build another one. Similarly, the old Marty on 2015 is not Marty Prime from the original timeline.

That seems to be what they were going for. Once Old Biff gets back to 2015 he is "erased" as the timeline corrects itself.

Whenever you start thinking too much about timetravel plots they always fall to shit because the whole idea of time travel is paradoxical to begin with.

The only reason Marty 'fades' is because his parents getting together is in danger of not happening.
