Erza, what would you do if you had a sister? *smiles*

Erza: I would first question if she has been at the tower of heaven. How had she escaped otherwise? Then we'd probably go shopping or something, catch up on all the time that we'd lost. And if she has magic (which I am sure she would) and doesn't have a guild, I'd invite her to join Fairy Tail.

Natsu and Gray: O.O if Erza had a...sister?
