ok, well we all know about the split after
OoT.
And in the AT, we see her as the fairy queen as a
child.
And the game after
OoT and MM on the CT, we dont see her at all.
So if this game did take place after
TP, then it would make sense that she would look older.
Also, at the split after
OoT, she became the Queen of Fairys in the AT.
But maybe instead of becoming the Queen of Fairys in the CT, the different events allowed this fairy to become fairy of the master sword/spirit of the master sword/whatever.
