Grover's gonna die, or another former major character like Frank, Piper, or Jason. See Annabeth's end of Ship of the Dead behavior. Probably by the hand of the Emperor that is 95% likely to be Caligula.

We'll get another pantheon mention and or reveal: With the Aztec Sun God in Book 1 confirming that pantheon (along with mention of Sol and Ra), and Book 2 having mention of Yoruba, Chinese, and Vedic/Indian...I suspect three other groups will be mentioned.

Perhaps Celtic, Slavic, and a Native American viewpoint, though I could see Mayan. Then again who'd have ever guessed Yoruba?
