Instead of keeping his back turned when handing him a wrench, why didn't Doc talk with himself face-to-face? He knew that Jennifer saw her older self without any consequences and that his doppelganger would have accepted the situation after an initial fright.
You would think that, with his intellect, he would have been able to handle speaking to his past self. But he insisted not to do it, so he practiced what he preached.
shareWho knows how the conversation could have gone. Despite claiming to never want to know anything about his future, he eventually figures what the hell and reads the letter, so who knows what seeing and interacting with his actual future self might have done to him. He may have been overwhelmed with the what the hell attitude and starting asking a bunch of questions. If the conversation went on too long other things could be altered in a way that prevented previous events from occurring. 85 Doc knew even though the Jennifers situation didn't blow up the universe, it also had little impact on changing future events.
shareThe original Poster was talking about face to face! Sure, the Jennifer sitch didn't blow up the universe but she passed out! If doc isn't there to scoop her up and out of the house -- then what!?
What if 85 Doc passes out and now he's out of commission --- pretty scary cause he's an essential part to furthering the plan at that moment!
I also was refering to Doc not talking face to face. I doubt 85 Doc would have passed out because he is aware of time travel , and the fact that he would be talking to his past self before he even turns around (again) , perhaps you mean 55.
I agree that the Jennifer situation still could have been bad, even though it could have made 'one' think that talking face to face is ok afterall.
I'm on the side that Doc's opinion was not changed by knowing this anyway, and he still refused to try to 'Talk To Himself' because there could still be risks.
55 Doc would most definitely have passed out, considering he did exactly that after seeing Marty return again so soon at the end of BTTF 2! 85 Doc probably knew this which was why he was trying to skulk away!
shareWhat would have been the point? On seeing herself, Jennifer fainted. Even if current Doc wouldn't have fainted due to being more prepared to meet himself, how do we know 1955 wouldn't have fainted?
1955 Doc was still attempting to get Marty back to the future, and if he fainted the work he was doing on that might've been delayed. That could've led to a paradox in itself.
Still a big risk, just so Doc could've gone; "Look, I'm meeting myself. lol "
Exactly! I think 85 Doc would have been fine. 55 Doc on the other hand wouldn’t have been. It would have created a major paradox because he wouldn’t be able to send Marty back to 1985
shareAccording to the rules of the movie, a paradox can be caused by any interaction with the past no matter how small. It's not really about whether or not someone will freak out. Even though the movie doesn't rely heavily on real science, it does go so far as to consider the butterfly effect.
