Continuity mistake: In the first BTTF movie, when Lorraine and Marty are sitting in the car, Lorraine takes off her coat and then asks Marty why he's so nervous. In this movie, when Marty is crouching down to get past the car, Lorraine looks at 1955 Marty and asks him why he's so nervous without taking off her coat.
Back to the Future Part II (1989)
Plot summary
Directed by: Robert Zemeckis
Starring: Christopher Lloyd, Michael J. Fox, Lea Thompson, Thomas F. Wilson, Elizabeth Shue
Dr. Emmett Brown takes Marty and Jennifer to the future to help their kids not to ruin their lives.
After doing that, Marty buys a sports almanac for 1950-2000, thinking it might help him in his time. Doc finds out and throws it away, but the 2015's Biff (very old now) finds it and uses the DeLorean to give the almanac to the young himself.
When Marty and Jennifer arrive back to their own time, they find it totally different - Biff is very rich, he practically owns the city, he married Marty's mom, killed his dad, and when Marty starts to ask about the almanac, he wants to kill him too.
Doc also finds out that he was imprisoned as a lunatic, so the two go back to 1955, the night of the Enchantment-Under-The-Sea party to take back the almanac.

Biff: Look, Lorraine, you walk out that door and I won't only cut off you, I'll cut off your kids.
Lorraine: You wouldn't!?
Biff: Oh, wouldn't I? First your daughter, Linda. I'll cancel all her credit cards. She can settle her debts with the bank all by herself. Your idiot son, Dave. I'll get his probation revoked. And as for Marty. Well, maybe you liked to have all three of your kids behind bars just like your brother Joey. One big happy jailbird family.
Trivia: When Doc and Marty arrive back in 1955 to stop the handover of the Almanac, there are 4 versions of the time machine in the area at that time - the one they just arrived in from the alternate 1985, the one Marty arrived in from the original 1985 in the first film, the one Biff arrived in from 2015 in the second film, and the one Doc buried in 1885 in the third film.

Answer: At the end of the first film, Doc says, "what the hell" in response to the letter Marty gave him. So this shows it is not that strong a conviction, especially in the face of definite knowledge about something bad happening. It is also a way for Doc to repay Marty.
