(You're Sanji)

Normally Zoro and Luffy are best friends but today Zoro finally told him he should stop acting like a child and don't underestimate enemies or dangers he's in. And at the end...Luffy said something shocking

Luffy:I hate you!! I don't want you being the second in command anymore!! And especially not my best friend anymore!! Nami is the new vice captain..!!

He just ran off while Zoro stood there shocked not knowing how to react. He really meant it.
