opted not to use the flashdrive because he didn't want to lose the memories he made in PC. But CM's Drew has absolutely talked about Navy Seal stuff. He mentioned it to Carly about sleep techniques FROM WHEN I WAS A NAVY SEAL! And wasn't that the reason he was so perfect to go rescue Liesl?
These writers have proven to be horrible with details. Korte has been there forever and should know better. Same with Frank V as exec producer. GH has an archive/bible to look this stuff up. I mean they have interns. They are just lazy.
To answer your question thusly--Drew still has Jason's memories but I think we are to believe that he has some of his Drew memories.
It's such trash writing and even worse continuity.
