Skip to 25:48. Aceto dispels the rumors that Derek nearly died backstage before the finals by telling his version of events. Apparently the promoter plucked him out of the audience and said Derek was gravely ill, and in Aceto's own telling, he "walked slowly backstage" like he was "walking through a mall (

), very slowly" which proves he knew Derek was fine (even though no one had told him what was wrong with Derek yet).
Contrary to reports Derek had seized up and had to be force-fed, Aceto says Derek was simply having a panic attack and everything was fine actually. He says his resting heart rate was "like a tennis father watching his son play tennis (

)", which means he was actually 100% fine and not knocking on death's door due to diuretic abuse.
Anyway there you have it folks, case closed!
