Wow, Tsuna's getting pretty aggressive/careless. "Mukuro, you bastard ...I'm way stronger than you!" He's never thought like that.
Tsuna was put in tough position, hm~ But it's not like he ever wanted to ally with CEDEF anyway.
Fon: "Why are you so fixated on Dino?"
Hibari: "That person is the first that's wanted to become my mentor. But an existence like that... I have no need for such a thing."
He might mean he doesn't need someone to help him get stronger, but I think what he means is that he doesn't need such an 'attachment' - it's best for him when he's a Lone Wolf. Even with Kusakabe he is distant, he keeps it to a boss-subordinate relationship.
Fon promised Hibari something~? Did Dino trick Hibari? :O
