Question: Why did Dunbar's superior kill himself as Dunbar was being taken to his new post?
Answer: Dunbar's superior supported the British ("The King is dead... Long live the King" said with a heavy British accent) and was likely a closet-case Redcoat his entire US military career. It was not rare and many suicides were a result of that.
This claim is not supported by the movie. "The King is dead. Long live the King" is a common idiom referring to the passing of power to someone new. It most definitely does not literally refer to the English King. The movie is set in the middle of Queen Victoria's reign. As for your assertion that there were a large number of English loyalists in the Union Army three generations after the Revolutionary War seems highly unlikely. Can you cite evidence of this?
Question: Is "Googolplex" an actual word?
Chosen answer: Yes. A "googol" is the number 10 raised to the 100th power, or a 1 followed by 100 zeroes. A "googolplex" is an even larger number - 10 raised to the power of a "googol", or represented as 1 followed by a "googol" zeroes.
Question: Why did the Aboriginal manservant hit Matthew Quigley on the head when he threw Marston out of his own house, after telling Quigley he wanted him to kill aborigines?
Answer: He felt that if Quigley fought Marston he might have been killed. He hit him to save his life.
Answer: In fact, it was more likely that in the beginning of the film he was in more of an "Uncle Tom" (for lack of a better term) and hits him because he feels he should help his "master." He later feels bad and by the end he has come to his senses which is why he doesn't make the same mistake twice.
More like he was emboldened because his master is dead. If not Quigley would have got a second thrashing from the aborigines.
Question: What happened to Doc's girlfriend from the first film? She risked her life to be with him at the end of Young Guns, so its a little odd that there's no mention of her in this film.
Answer: Doc says in the movie he is married with kids. So you have to assume he married her.
Answer: He was mentally disturbed and was depressed about being assigned to a "dead end" post with no chance at advancement. Dunbar, the hero, choosing to be assigned to the frontier, just pushed the poor soul over the edge.

In a word, the disease syphilis. The urinary tract problems and the Insanity are possible side effects.
What are you basing this on? What in the movie indicates that he has syphilis?
