Thanatos mentions that a special guide is needed to lead them  to the doors of death. That only a certain type of demigod can read the signs. That they will have to quest in Rome. Which of the 7 does everyone think it is?

Percy, Jason, Anabeth, Piper, Leo, Hazel, or Frank?

I think its Annabeth. Due to the mark of Athena burning through Rome bit.
