User blog comment:FairyRaven/Fairy Tail Chapter 423: Do It All for Love, Review and Commentary/@comment-87.202.75.211-20150309114538

About Chelia's age. She is 16 now. Also, the Second Origin thing is kind of unexplained. When team Natsu + Levy and Wendy obtained it, they were all in pain baring Erza. That lead to speculations even among the vcharacters about Erza already having the 2d origin. Well, if it is true, then i expect Laxus, Bluenote and evry guy who is wizard saint level to have it as well. It is said that it is unlocked via training, so Gajeel might have it too.
