You all are forgetting something important the only reason she looks different is because she was freed she uses the same avatar for Titania and her normal account for ALO. So since the reincarnation update was never released she was an undine the entire time. Plus we get a hint of it when Kirito says there is an Undine and Spriggan Alliance, yet he hasn't meet any undines at that point. Unless Agil recognized her as an Undine because we've seen he has played the game before.
