this used to bother me, but i've been thinking about this. i think every time a character dies, and the next episode they are alive, that this is actually an alternate timeline Dandy unknowingly created. we have seen that he has some strange ability to travel through space time, and he seems to be unaware of this. while they could do a better job portraying this, and this is only a theory, this is what i think is happening. and later on, i hope that this will be expanded on and a larger plot might develop.
they sure are taking their time with it, though.
