So I just thought of something. From a technical standpoint, Hazel is an escaped soul from the Underworld, but Pluto never reported her as missing to allow her to live her life. So on paper, Hazel is still dead and in the Underworld. Does that mean that Hazel is technically immortal as long as she isn't killed? I mean death is never going to come for her as she is already reported dead, so will she just live forever? Does Hazel even age? I don't know.
