its not impossible but there isn't enough proof to say that rinoa is definetly ultimecia. SB has explained everything. ultimecia could be nearly any female character in this game. its not impossible. but there is no solid proof. the R=U theory i good and the evidence it brings up is also good but it has been disproven. i like the theory but there is no solid evidence that say that rinoa must be ultimecia.WHY can't Rinoa possibly be Ultimecia?
