Marty apparently starts fading AFTER his grandfather was beaten to death. Later, even when he travels back earlier in the day, to a time BEFORE his grandfather was in any perceivable danger, he continues to have fading 'spasms' which get progressively worse. But that really doesn't make sense.
As per the rules in BTTF1, the moment Arthur McFly died, Marty would simply fade from existence. Period. There is no way Marty can continue to exist in a time period where Arthur McFly is dead, because the probability of his existence if 0.
Also, when Marty goes back to a time BEFORE Arthur McFly was killed, he should be fine. Or at any rate, the fading shouldn't be AS bad, because there is now a probability that Marty could exist.
i'm kind of unclear on the timeline for those few days; Marty arrives June 13th 1931, June 14th is the day the murders happen so I'm assuming the newspaper he reads was printed june 15th? (I know Marty says in episode 1 he's going to the day before doc gets killed)
Arthur gives his deposition around 4 pm, in episode 2 Marty goes back to 4:45. The question is at what point is Artie killed? Also what time is the ending of ep1/begginning of 2? Seems artie got beat to death (doesn't make sense to me how he'd be found, Kid has an underground speakeasy, you'd think he'd dispose of the body?) Kid is obviously driving the police truck doc is in, had he killed Artie yet?
