something about water, how it replenishes as much as it takes life, and how that reflects in percy... thalia and nico and hazel and jason, their powers take from them, it takes their energy and sometimes a huge amount of life, takes it all to protect them. but percy.. water replenishes him. it heals him, it is a part of him, it is his very essence. it is, to put it frankly, his home.

water does not take from its own - it supports it, which is why percy was so easily able to control it in the river lethe, then again in the styx, then again with the cocytus, akhlys' tears and poison. water bends to its will, it's master. it literally praises him, worships him. the earth does not worship nico - it takes from him. the air spares no mercy, even when it comes with it's own child.

it's just- it's so obvious how there is saltwater in percy's blood, how children of the sea are far more fearsome than most. there is a reason why the romans fear the sea, fear Neptune, fear his children. because the others work for their power, but Percy and his brothers, his sisters, his father, they make their powers work for them

literally the only times percy wore himself out with his powers was mt. saint helens and controlling the lethe, which were completely understandable so.

that is where the power imbalance lies in. zeus' kids wear it like a crown, a heavy weight above them, a reign to horses that are hard to control. hades' kids wear it like a burden, like a cross. it is as heavy as the earth they control. but poseidon's kids..... it is water. they are fluid, light, dense where others are not.

i also think that this is why their fatal flaw is loyalty - with water in their essence, i think it was appropriate for this to reflect in their personality and downfall as well. water is loyal to those that are part of it, and that is as much advantage as it is weakness.
