(okay here is just a analysis; riptide is just raz's subconsciousness. riptide is Raz's Regrets, rage, Anger, Sadness, Bad moods all in one small compartment. but its also fused with one other mind who is forcing raz to use his hydrokinesis for the bad like his subconsciousness, who drowned millions just to stop the torture. hes just trying to stop the tortue. basically riptide is raz's creation to cope. )
