I missed aero for a while. Reflect does take it's place.
For my first play through i thought it was in the traditional FF sense, where it reflects spells... so i played through without it >.< (I wish they'd made Roxas compatable with spells though.)
Something i thought should be brought up,
Someone mentioned how Roxas did not remember her, yet remember all the others?
It's either really strange, or a coincidence that NONE of the Org. mention her?
It's quite possible that all of the Org. forgot.
But that's just one theory.
I think it would make sense if it was the 14th member.
If she did something that would make the organisation need to kill her, it could explain why they never changed the name to Organisation XIV.
Although 13 vs 1? This girl would need to be super strong :| (Unless you kill her as Roxas)
