Flash Freeze

Seifer's latent power is Water, which given it's frequent ties to the Moon doesn't bother him in the slightest. At the moment, however, possibly reflecting the chilly reception Seifer is likely to give strangers after the betrayal by those he was closest to, his water magic is prone to flash freeze, already cold in the wielding, it turns to ice within seconds of being cast, either drenching the subject in absoloutely frigid water or becoming flying jags of ice just to make the point that your reception is -anything- but warm. 

Time will tell if he can be convinced to thaw a bit.
