Seriously, what is going on with These "20 years". There must be something more than just an idea or an old Story behind it. Why tf were they sent exactly 20 years into the future, why did Oden exactly this obviously way before the fight? So it seems to be no decision of the Moment, it seemes to be well planed. But why These 20 years... is it really just a prophecy about someone coming exactly then? There must be something more...
