Oh btw, the best "Who is Irene?" theory I've read so far that incorporates what we already know from the story is that Irene is Erza Knightwalker. And before you all scream false remember that Irene looks older, BUT Erza was trapped on Tenrou for seven years and didn't age during that time. It also means that the "I am you" line is pretty much true due to the parallel-self stuff.

Do I think this theory will turn out to be correct? No, but I like it for actually at least making sense within the already-developed plot, which I have a sneaking suspicion the canon reveal won't .-.
