Myron was an obnoxious, adolescent genius, and the inventor of jet, which he invented to aid the Mordino family's vile exploits and also in exchange for prostitutes, a laboratory, and cash. He could be found wasting time at the Stables in the basement. The Stables are located north of New Reno.
Curiously, he is a racist and hates Marcus. Myron died around 2242, less than a year after the defeat of the Enclave, stabbed by a Jet addict while drinking in the Den. His discovery of jet was quickly forgotten, and now there is no one who remembers his name.
He will join the Chosen One if they play to his ego and convince him that leaving town might make the Mordinos realize how valuable he is to them.
While usually inept in combat, Myron is a skilled chemist, and can make antidotes, stimpaks and super stimpaks if the Chosen One gives him the proper ingredients. He is more of a scientific genius than a fighter as he possesses a good Science skill.
He can get the Chosen One the cure for jet addiction if their Speech skills and Intelligence are high enough.
A female charismatic (or Porn Star) will change his dialogue tree to a sexual tone with the Chosen One.
In addition, if a female Chosen One has a low Intelligence, or Endurance, Myron will offer her a spiked drink when first talked to, potentially to sleep with her.
If the Chosen One comes to the Stables by car, Myron will comment on it.
Even if he dies during the game, he will always have the same ending.
In the Shark Club, in New Reno, the comedian there will eventually start making fun of Myron.
Since Myron is a teenager, he is considered a child and killing him counts towards the Childkiller reputation.
The exception to the above is to take him to the Sierra Army Depot, down to the fourth level and leave him in the room alone with the automated organ extraction table. Once it is activated, he dies a horrible violent death and his brain is removed without penalty.
Myron disgusts John Cassidy because Cassidy hates chems - and Myron created Jet. Not to mention that Myron is also a pretty horrible guy overall, what with him being supportive of slavery and the killing of more than a hundred slaves to perfect a drug. The clincher though might just be that Myron is a very big coward at heart.
