Ok so I've read more than a few pjo fanfics where something is done  to the demigods, mainly Percy via magic.

Does anyone else think that after sally makes sure they (the demigods) are ok that she'd march up to Olympus and shoot the responsible party for harming "her kids" with the shotgun she stole in TLO?

Like a spell goes wrong, one which the demigods never consented to anyway, and the demigods are turned into younger children and we are just expected to believe Sally would be ok raising a seven year old Percy again...pretty sure she'd internally flip and swear vengeance on the god that did it, and probably trick Poseidon to get to the god for her vengeance.
