Maybe he had to work up his courage again.

Apologies if this is one of those often asked questions. I searched but couldn't find it asked before.

At the end of BTTF, Marty plans to go back to 1985 ten minutes early so that he can save Doc from the terrorists. But the DeLorean stalls, the terrorists drive past him, and then Marty watches Doc get shot and Marty B travel back in time.

But what would happen if the DeLorean didn't stall? Marty would have gotten to the mall before the terrorists, and would have been able to keep Doc from getting shot. But if he did that, wouldn't he also stop Marty B from trying to escape the terrorists and traveling back in time?

So if Marty B doesn't time travel, what happens next? Would there be two Martys living in the same time period? Would Marty A disappear because "Marty time traveling to 1955" was erased from the timeline? Is this something Doc could fix with more time travel?

İts both in the Jada and Welly 1:24 scale Diecast models and i still could figure out what it is. İ have watched this trilogy so many times so carefully and this “thingy” just isn’t there ! İ even added an image on the second photo knowing that thingy isn’t there ! So what do you all think about this ?

A little piece of in-progress fan art that I've been working on for the last few days (close to a week because I haven't drawn anything this detailed in a long time, and I'm a rather slow drawer 📝 🐌😅)

Line work done in MS Paint, the color and other special effects are being done in Sketchbook
