You miss many of my points, Utter.

Although you mentioned in passing that Riptide won't kill Harry, you still ignored the part where the only matter that Riptide will destroy is celestial matter - i.e. demigod flesh. Normal regular (if magical) wands are immune. And I guess Cfp is misrepresenting Harry quite poorly here. It's a shame.

"Magical water is still water. It should still be helpful to Percy." Poseidon's domain over water likely excludes water with magical properties that make it something besides water. The Hogwarts lake is magick'd up with defining features that prevent non-wizards from accessing it - much like Hogwarts Castle itself. I'm certain that this feature extends across the entire Hogwarts grounds.

"I highly doubt that Percy would fight Blackjack." That helps prove my point, not yours. If Harry imperio'd Blackjack into fighting Percy, Percy would be too horrified to fight back and would have the ever-loving crap beaten out of him.

"Poseidon being his dad and all, I'd imagine he'd be willing to keep Blackjack from being brainwashed." Except, y'know, for the part where Percy has no divine intervention to help him in this fight.
