User blog comment:Sargenttacos115/Natsu and Gajeel age Theory/@comment-98.70.201.92-20140417020601

I think this a good theory as to why they were not able to go thought the age runes, and to explain the memory gaps or holes it is possible that the dragons put a memory charm on them like on the tenrou island arc "which if one cast by a rune knight could fool gildarts and makarov what do think one cast by a dragon could do" this would explain why natsu knew with out a doubt when his dragon disappeared but couldn't read or write. the only major flaw I can find is Porlyusica she claimed to be the edolas grandina and assuming time passes at the same rate as it does in earthland that would make Porlyusica 400+ years old so for the theory to fit either Porlyusica is hiding some made anti-aging cream or she lied and is really gandina and used edolas as a scape goat. all that being said it is possible the runes were just faulty.
