In the 911 transcripts if you want to believe it verbatim you heard Eric first yell "Vodka come here" then supposedly after he broke his nose he said "I'm okay Dylan"
In Dylan's journal he calls Eric by his first name but in Rampart Range he says "Reb" in the Car Wax commercial Eric calls Dylan by his name.
From some of the 911 calls, I think at least two of Eric's coworkers called him "Reb Harris" instead of Eric.
I don't know anyone but Eric, Zach and Devon who called Dylan Vodka. Granted the only time I heard Devon and Zach refer to him as Vodka was in Dylan's 17th birthday card Devon made for him.
Do you think there is a reason on 4/20 that Eric went back and forth? I don't remember anyone saying Dylan yelled for "Reb" or "Eric" but we always assume that Eric took the name Reb and created him like it was a character, but Dylan looked at Vodka or "V" as just a nickname because he drank vodka really fast. Though we never heard the story of how that came to be. I want to know what size the bottle of vodka was that he chugged in one sitting... russian blood I guess.
