1. Who is Argus? (in book one)

2. Where can I find a description of Thalia?

3. What happened to Tyson in book 2?

4. Where in book 3 does Annabeth say "something serious" to Percy in the gym? I can't find it in the book... Because on page 32 it says 'What had Annabeth wanted to tell me in the gym? Something serious, she'd said.'

P.S: I don't want to know what she wants to tell him I want to know the page where she says the words Something serious to Percy.

(I'm on page 44 of book three so no spoilers please)
