Gershon tells the complete story in the muckmouth interview, and from the way he tells it, he had it out for Reynolds before they even met, and was just looking for a reason to beef. Some lowkey jealous nigga type shit.
It was over a free 1/2 ounce of weed that was given to the Globe group in Australia. Gershon thought that Reynolds smoked more than his fair share, and confronted him about, but it wasn't brought up again until later at a trade show, and again at the City Stars premiere, where the fight occurred. In the original story Maldonado broke up the fight, and Gershon was about to go after him as well. This time I guess it was J. Strickland.
Edit: Also in the Chromball Reynolds interview they reference, the timelines are switched around, and the agenda meeting is told drastically different.
100% agreed dude is salty, and definately on some psych shit. If that edit was an attempt to make the interview more coherent I would hate to hear the actual audio. Answers were beyond tangential and even when he did actually address questions, the response was quickly followed by non-sequiturs. Tough read, but I powered through.
