I like the distinction Hibari made about pride. It got Tsuna thinking, at least.
Hibird's head was in the way. XP Wonder if Hibari was afraid of hitting him.
TBH the last couple of fights haven't interested me much, but there's been enough interactions and past memories revealed to keep me going.
Crap, Hibari's yawn made, too. Z_Z
Just because Hibari hasn't had as much interaction as he did during the school-time arc in the beginning doesn't mean he's lost all of the things he did then (yawning, for instance).
And I think it's fitting that he's finally saying a few more things than usual, when we're at such a deep point in Vongola history. Otherwise I really would wonder what the point of his character is, besides acting typically calm and badass.
All of the guardians are there for a reason and play a part. Just as Vongola has changed him (where else did Hibird come from? and he's gotten much stronger under Dino and got the power from Vongola), so must he change Vongola in some way.
