They have all their memories by now. Its been a long time for Jason to regain them because they were working on the Argo II. And at the end of the Lost Hero he had all of it back. So he has them back.

Same for Percy. The Gorgons blood cured him. He remembered everything, (which made me so happy.) Percy regained it in the 4 hours they were riding Arion to Camp Jupiter.
