Ok, I saw this was brought up briefly in another thread, but I'm seeking a more detailed conversation on the matter. At the end of episode 2, Marty and Doc fly into the lightning bolt. It seems like Doc was trying to cover himself, and then we see Marty wake up in the crashed delorean without Doc there.
It doesn't make sense to believe that Doc has disappeared. First of all, then Marty would have disappeared too. Also, in BTTF2, they didn't disappear in Biff's alternate timeline. So, it has already been established, that alternate selves don't make the time-travelling selves disappear.
If this is the case though, then where (or when) the hell is the original Doc!?
Do you guys think he might have jumped out of the car before they hit the lightning bolt? Do you think maybe he's also in this alternate 1986 somewhere, and somehow got out of the delorean before Marty woke up? What are your thoughts?
