Do you remember one episode that had mention the past seasons? I can't. We have many references to second and third season, for example the knee pad(? Sorry, I'm new in this lingo) and the words about be exhausting.
Do you heard Buck? He wasn't be exhausting. Why? He still remember the words from Eddie in the third season and he never forgot that. I'm really shocked about that. And he thinks that he is exhausting, he was sad about that when he talked with Tommy. He isn't exhausting!
It didn't work, he forgave but he never forgot his words
I should say it, The trials of Apollo are fantastic books, among all books of Rick Riordan, this is special.
The problems, the psychology and the mitology is amazing. These books have several problems and I understand it. Zeus and Neron, the fatherhood, the growth and maturity of every character.
The development of Apollo is amazing.
So, I at last finish this saga. I read the last book in one day.
Percy Jackson said in Greek Gods book, that Dionisius was who brought the wine to India and for that he adopted the tiger and other animals for sacred animal.
