Now that most ppl.r back, I m quite sure of it. I have based my theory on 2 possibilities-
1-I remember Kabuto saying that he could nt revive jiraya bcuz he was under the deep oceans. If he was talking about water pressure, then being a snake he should be able to withstand that. I remember the place where jiraya died. It died nt look look as deep as the mid-oceans. I thnk kishi did that to fool us to make us thnk he had really died. What I thnk is that he somehow survived then. I thnk he was resting his wounds all this while.
2-Using renne tensei no jutsu it is possible to bring someone back to life even if his body was destroyed into a 100 pieces like many konoha shinobis when pain attacked or someone who had died long ago like Madara. Then it's possible that when nagato brought back the ones he killed, Jiraya was also revived.
