I don't think Christoph was the one who killed that guy, though? Didn't he freeze up and have to be rescued by Cecilia, which is the reason why he's sulking right now?

Oh, I remember now... You're right. He did kill him in the end, and Cecilia got upset because with the guy dead they couldn't extract any information.
Sorry about the confusion.

I still believe that Christoph is the one poison Lucaon, remember when he gave the idea to Kyon to ask Lucaon to eat together. I think he is smart and he is using Lucaon feelings for Kyon in order to stay under cover. Remember he could be a ZERO acting only by order. Let's see how is the story going to be???
he is the one poisoning Lucaon no wonder he killed that zero guy from previous chapter....what do you think guys???
