The MC's original death has served its function, I feel. It put us in the new body, gives us our power and the link with the goddess.
What's more interesting to me is the sleeve's (recipient body) death. How did he get into a coma with apparently no physical damage and why did he choose not to return when given the choice? He was relatively well off, had a great family, ok appearance wise, a functioning D and doing well in college. On the surface, every reason to return.
Given who his "best bro" is, could it be that he was actually a loser creep just like David was in DP and headed for a fall/major exposure? There may yet be a twist to unfold in the story of the body the MC now inhabits.
