Riptide saw his brother Mizu's death, he obviously was traumatized by it and he now refused to go near water in fear an alligator will snatch him up as well.
It's a pretty sad life being named Riptide but being afraid of water, not to mention the fact that he now will only drink from puddles or water brought to him by another wolf requires... A lot of patience and might even get him killed.
Hopefully, he'll meet someone that can help him heal in the near future.
Mizu sometimes appears in his dreams in hopes to help him but so far it hasn't really helped.
As Riptide grew older his fear of water lessened and he was able to get his own water to drink, though he would still never enter the water, he would need someone to help him get through this but he hasn't had too much luck with that yet.
