SPOILER ALERT!
One Piece, Vol 50: Arriving Again - Bink's Brew!

I love the headings of the question corner done by fans around Japan. And what Zolo does for Luffy after the battle on the Zombie island was amazing.
-------------------------------------------
I love you Zolo! Seriously, I tear up every time.
...and Brook!
This is an emotionally draining volume. And I love the song Bink's Brew.
