User blog comment:Sargenttacos115/Natsu and Gajeel age Theory/@comment-98.150.140.51-20140303071038

Did anyone notice that when Natsu and Gajeel tried to get out of the barrier, there were those weird red runes that stopped them. However, when Markarov tried, those red runes didn't appear. I don't think it has anything to do with their ages, but something different, like their magic. However, it might be red because of a technicality, such as "even though their bodies haven't aged beyond 80 years, they have existed for more than 80 years” in which case they very well could be from the past.
