Right, i reckon students will always beat their masters because the students always surpass the previous generation its the rule! (see oro vs the 3rd, you can't say that it was just oro getting really really lucky or whatever). Also i reckon this isn't the end for either Jiraiya or Pain because i doubt or at least hope that a staple character like Jiraiya wont be killed off here by leader of some little resistance that has stupid ideas of ruling the world. Also Pain wont die because he has only just been properly introduced and as akasuki leader and owner of some kick ass powerful eyes will not be killed by the old pervert hermit that is Jyraiya. But seriously Both of these Ninja are capable of fighting each other and escaping with there lives intact.
