Who do Ты think the new character in the Mark of Athena will be?

I think it will be a character named Bobby. Why? Well, in chapter 50 of LH, it mentions several people that Jason was starting to remember: "Dakota, Gwendolyn, Hazel, Bobby. And Reyna." All of those people (except Bobby) were introduced in SoN. He was briefly mentioned in SoN, but it only сказал(-а) that he gave them a ride on Hannibal. Other than his name, we know nothing about him. Soooo...I'm guessing it is going to be him.

I agree but with one little idea since death сказал(-а) one kind of demigod it could mean that she-or he-could be Greek and roman in a way....do Ты get what Im saying? It's like Percy and Jason but to the extreme so I guess еще like nico except she/he is accepted more. She/he doesn't belong to one camp. Do Ты get what I'm trying to say here??

I think the new demigod will be a monkey, who is the sun of Hermes, who throws bananas at monsters. He will be the one fo find the Doors of Death with his awshum psychic powers. I think I spelt a word wrong.... O.o
Sorry.... that was random... XD

I don't think it will be a son/daughter of Neptune and i a willing to give Ты an entire stock of blue Шоколад chip печенье courtesy of Sally Jackson. Sadly I have no idea who the new character will be, but I can`t wait to find out.

It will be a person. I hope.

omg that would be amazing if if Percy had a sister!

aww yeah i was hoping it's a daughter of Neptune too! high 5, i was betting on the same thing. since there's Jason-Thalia and Hazel-Nico, Percy should have like a Roman counterpart или something!! :D

What if it's a person who died before came back to life when the Doors of Death were open. (example:Luke,Bianca etc)

universalpowa, i see your bet and raise with Riptide, Annabeth's invis hat, and Thaila's shield Ageis that it's either : A. Nico diAngelo, B. Annabeth, C.Bianca diAngelo come back from the dead (not sure on that, but it would make sense), или D. a new, VERY destructive son/daughter of Neptune или Zeus (to storm или огонь the world must fall).
