Many here assumed Piro is/was a medic because Alan wants to be a medic and in the Navy “like Piro”. Although we still don’t know what the subject of the tech manuals Piro edits is.
I’m inclined to think that Piro was formerly in the Navy, not currently (and not necessarily with medical training). And Alan, 11 going on 12 isn’t “practically a teen” but closer to a teenager than the other children. Speaking Hindi isn’t farfetched. And the tuba playing could be game related. 12 toes, maybe there’s a polydactyl cat at home.
… “she” talked back!
