User blog comment:Misakichii/Which Demigod will lead the 7 to the Doors of Death?/@comment-3177105-20111106162252

i think its annabeth as for wisdom daughter its heavily hinted to be annabeth or like me most of the readers want her to be the 7th in the prophecy. ...and then walking alone may mean she has to read the map to doors of death alone (as thantos said one of them will have the ability to read it as its not a physical place(like calypso's island) ....maybe its the cool powers she has which were not discovered earlier ) and we know that for finding them they would have to sail to rome first ..its likely athena's mark will burn to guide annabeth to the doors of death......as she is the wisdom daughter ,only she would have the ability to follow it.
