Myron is a child-genius and chemist from the town of Redding. Furthermore he is the creator of jet; which he invented to aid the Mordinos family's vile exploits and also to barter for prostitutes, a laboratory, and cash. He can be found wasting time at the Stables in the basement. The Stables are located north of New Reno.
Curiously, Myron hates Marcus due to him being a super mutant. Myron dies 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; since then no one remembers his name. His invention, however, continued to grow in popularity and reached the East Coast of America in the Capital Wasteland and the Commonwealth.
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. However, using organ extraction (on any companion) results in high negative karma.
Due to being the creator of jet, Myron disgusts John Cassidy as he hates chems. 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.
Myron will refuse to travel with the chosen one if Marcus is in the party, saying that he "doesn't hang with mutant trash," to which he will speak to Marcus, saying "ah-heh, no offense, big guy."
