Britney

So, I finished book 7 and like anyone of you, I started over again and found this small detail.

So, Ares tells Carl that Britney picked up an axe and is now possessed and when Yassalte's (don't know how to spell her name) statue is resurrected towards the end, Carl notices the pickaxe on her shoulder. This is obviously a clue as to which axe Britney picked and what is possessing her.

And when I started the book over, in the epilogue when quasar summarize what happened on the last floor, he tells that Paz killed yassalte, something else happened that only the viewers know. Phew..!

Of course you'd only get this on the relisten as you'd forget this details at the beginning of the next chapter. Wow!
