You were training at Mihawk's castle during the 2 year time-skip. You heard Zoro and Perona fighting like usual, Mihawk just drinking coffee and reading a newspaper. However, Mihawk was slowly getting irritated at all the noise that the two were making.

Zoro: "YOU'RE SO ANNOYING!!"

Perona: "NO, YOU ARE!!!"

The argument only gets louder and louder...
