Sorry to revive an old thread. I thought it would be better than starting a new one, considering that this one is already filled with interesting theories.
Has anyone wondered why Manny was a Reaper, but someone like Nick wasn't? I'm sure we all agree that Nick is a rotten egg compared to Manny. Why didn't he have to work off a debt?
a) Manny's life was worse than Nick's
b) Nick only became truly corrupted after death
c) Nick has already worked off his debt (unlikely, if you ask me; he just doesn't have that air around him and you'd think he might have learned something if he had)
d) something else, what?
