User blog comment:Sargenttacos115/Natsu and Gajeel age Theory/@comment-50.81.137.208-20140618174852

I personally think you made a good point except for two holes in that logic. 1. The dragons were seen in another dimension after the battle of fairy tail arc (tower of heaven arc if you go by the manga) 2. You have to use time travel science when you think about the barrier; think about it like this: if natsu and gajeel were sent into the future they would still be the same age as they were thus being recognized by the barrier as teenagers, no older
