Articuno

Percy jackson (AKA Articuno) was kidnaped by someone unknown and his memory wiped, will he remember his past or will he stay confuse for the rest of his life?
Nobody knows who he is, or who his godly-parent is, all they know is that percy was poisoned and and melted into shadows during the ending ceremony at camp half-blood. And then eight month later a weird guy shows up and is all dark and weird but is deadly with any weapon at hand. ( even a pen)
Will they ever get percy back or will he be gone forever??
