Hmm, now I'm wondering if maybe something else is responsible for the outbursts with Eric. Maybe even 3V, like "don't tread on me." I've seen him express jealousy, too, over others who seem to be doing well building their channels. My understanding so far of 3V is that it can be sort of undermining of others' success (not sure if I'm understanding that correctly, though).
It seems like 3E people actually avoid emotional displays or expressing emotion unless prodded beyond endurance. But maybe it depends on other aspects of your personality, like introversion/extraversion?
Does he encourage others to express emotion freely? That could mean 2E or 4E. I haven't seen enough of his videos to decide. Maybe 4E since his own expressions are kind of in the child stage, like a storm that passes quickly through. I'm wondering if he could be 3V 4E... (or 2E 3V)
