You know, I cringed everytime I heard someone say that but right now after reading this chapter I somehow…well don´t think it is that unlikely.
haha yeah I know what you mean… all those "dead guys return" theories... i can't stand em... anyhow moria wouldn't do that because brook stated that moria doesn't want to create zombies stronger than him, since they will disobey his orders. Luffys' shadow + Rogers body would probably be increadible strong lol.
