i think this is what will happen in HoH or the 5th book. Chryasoar captures Frank,Hazel and percy for some reason.

Chryasoar: Come and join me, daughter of Pluto!!!

Hazel:Never, you monster!

Chrys:No? Well, I guess I can't wash away your curse then!

[Hazel looks on in shock]

Chrys: Yes, it is as the fates ordained! I am the one who shall wash away your curse. My deal is simple. Leave your friends and join me, or perish with them.

Frank: No, hazel, don't believe him!!

Chrys: Shut up!!!

[Proceeds to whack Frank]

Hazel: It's tempting, but no!!! [Charges chrys]

Percy: No, don't!!! You'll die!

Frank: No, this is her duty. Don't you see? Mars said that this was the sacrifice that you could not bear.

Hazel dies, frank and percy are freed.

frank burns his stick in order to give hazel life.
