[ The first time Five shows any strong emotion after finding him eating a hand, anger is the first one that surfaces. He's angry that he was kept in the dark by the Merchant yet again, angry that Kaneki seems so disappointed to be confronted about his disturbing diet, but most of all angry that he seems so wrapped up in hunger that he spoiled a perfect opportunity to learn something he can use.
