Jason only memory was of Thalia and Percy's was of Annabeth. Percy fatal flaw is his loyalty to his friends and obviously Annabeth is his closest friend. Jason's memory was of his sister which was someone who was important in the past. Plus, it's not like they got to choose what memory they remembered. It was all Hera/Juno's doing.
