Aries is cool, Draupnir2005, but i think that Aeris is much cooler, and she is a character in the game, not part of the Zodiac...
You can also pretend that she is coming back to life in that final scene like so many people want to, when you think of the three times you see her face in that same manner.
Beginning of the game - Eyes open - Life
End of the first disk - Eyes closing - Death
End of the Game - Eyes opening - rebirth/resurrection
