It's obvious that Squall is a Virgo, good lord. He can't even get to sleep at night without his favorite copy of the Balamb Garden rules and regualtions handbook. Perhaps that is why he never knew what to do with Rinoa. He could never find the proper handbook or any form of rules or standards to help know what he has to do with her in order to keep the universe neat and orderly.

Now that I think about it. I don't think there are any Scorpios in the main FF series. (T.G. Cid from FFT but no one from the main twelve.)
