User blog comment:KrspaceT/The Seventh Demigod; Something unexpected?/@comment-112.204.138.251-20111015072004

at first i think it would be annabeth, but she's just not powerful enough.. her power is.. her brain? intelligence?! invisibility (cap)?

the 7 demigods should be powerful (percy - sea/water; jason - lightning/air; leo - fire; frank - shape shifter; hazel - riches of the earth/earth-based powers; piper - charm speak)

reyna is not that powerful, she's just a skillful warrior, annabeth - strategies, nico is missing, thalia??! i doubt because the demigods have different god parent (jupiter, poseidon, hades, ares, aphrodite, hephaestus) so maybe children from athena (annabeth?! or another sibling) hermes, demeter, apollo, dionysus...

but most likely annabeth or another NEW demigod (apollo's?!)
