Cedric just shook his head, head still bowed for a moment. "I can't ever imagine what Azkaban is like, and I'm so sorry. But that still doesn't mean it's your fault."

He made an attempt at eye contact, his voice dropping seriously. "Harry and I were too slow to catch on to what was happening in the graveyard, and he's the one who convinced me to take the cup with him. But that doesn't make my death his fault either."
