No problem! Nice to hear that.
Also I agree on us both thinking fourth dimensionally lol.
And what you said was correct on how I view it.
To me the Marty we follow is the Alpha-Marty. The Marty that changes things. (Same applies to Doc)
Ofcourse the past version of person can still change something, but this because it is directly or indirectly influenced by the Alpha version.
(Like how 1955 Doc plans to wear a Bullet-Proof Vest in 1985)
The problem I have with your way of viewing is to accept everything already is pre-determined.
Meaning the Doc was supposed to get hit by lightning and return to 1885 thus the DeLorean is already there.
