If Emmett Brown died in 1885, which was seen in 1955, which is not usually 1955, it might be 1955A, which is alternate. Also, if Emmett is 30 years older, will he be erased from existence because his 30 years older self died? –ImpossibleChriz5719 (talk) 13:16, November 14, 2015 (UTC)

1955A exists in BTTF fan-made or alternate videos, At least, Doc will not erase from existence if the DeLorean is broken or the clocktower's ledge has been repaired Doc did not die in 1955A because of the 3/4 wrench that he given to the 1955 Doc, 1885 Doc has a position required for September 16, 1955A 2:04 PM, Doc usually doesn't die in 1955A due to his basical serious life and the Tannens' guns which are jammed from the newspaper which Marty reads in 3:00 AM.  The New CM95 (talk) 13:30, November 21, 2015 (UTC)

The 1955A (referred to as Timeline 7 elsewhere here) is what we see for the remainder of Part II, after the DeLorean gets struck by lightning, and the first minutes of Part III until Marty leaves the Drive-In Theater.  Since it's 65 year old Doc who has been killed in 1885, 35 year old Doc wouldn't disappear, but he would spend the years 1955 to 1985 wondering (a) whether his older self is still going to get killed in 1885 and (b) whether Marty will ever make it back to 1985 a second time.  T-7 Doc of 1985 would have a lot of paradoxes to consider and, if he does nothing, I think he would disappear at age 66.  McFord (talk) 20:04, November 23, 2015 (UTC)
