but when Carter described Percy he didn't say anything about the SPQR tattoo so it coudn't have been after HoO series. Maybe in between tLO and tLH would make more since because Carter really wouldn't be on Percy's mind much sense everything thats happening is only on his side of the magical world. You also gotta remember Hera took Percy's memories so she might have that particular one locked up somewhere only she can get too-at least until the Heroes save Olympus-before mixing egyptians into their lives but then again only Rick truly knows.
