Мафия 13. Inanimate Paradise

If Krabby were a doppelganger, he wouldn't have died.

So, does that mean the doppelganger of the attacker kills him, but the doppelganger itself survives? How do you kill it then? :eek:
In that case, nothing is clear at all... Or rather, it would be clearer if it weren't for this quote from Dostoevsky.
