Actually Reborn is in a problematic situation. Tsuna has already lost Mukuro to Verde, and is almost definite to lose Hibari to Fon. And given the information given in this week's chapter, he may still lose Yamamoto (to Giglio Nero or Varia), Lambo (to Fon), Ryohei (to CEDEF), and Chrome (if she decides to stay with Mukuro instead). The Cavallone are sitting ducks without Dino, and Dino is a sitting duck without his people.
