Upon re-watch:

Spoiler for Chocolate:

There seem to be quite a few dramatic bitings-of-chocolate-bars... But what does our friend Mello do with all the pieces? He has thus far not been seen actually eating them, even when biting off 2 pieces relatively close together mid-conversation. Perhaps he actually is not a chocolate fan, but simply likes the pleasing snapping sound when it breaks? Or perhaps he has an unexplained hatred of chocolate that drives him to an obsession to break it into little bits? Or maybe he's just a fast eater.
