Some people say that Percy faced his fatal flaw when he allowed Jason, Piper and Leo to fight Gaia at CHB. I don't buy that because it was insignificant. And Percy Jackson already did that thing in the House of Hades.

I thought facing his fatal flaw meant sacrificing his friend for power.

I agree with you about not having a twist. They figured out the prophecy in the House of Hades.
