Scar is in the wrong spot to be a C-section, so I'm ruling that theory out (at least for now in case Hiro is pulling some creative liberty on the scar's location). Now I am curious why it's in the exact same spot where Kyôka tore a chunk out of Erza's abdomen in the last chapter, though it looks like Erza's is more convex shaped and Irene's scar is concave.

On a side note Irene's hair must be a pain to braid. If it's that long and poofy braided imagine what it's like loose. Must be a nightmare in humid weather, no wonder she's up North with Bradman and the other shield.
