Spoiler for ep 6:

So it was a mix up of people and the guy behind the deaths is a next. Too bad there goes Barnaby's link to the Ouroboros again. So the guy he's after has the mark on his hand.

I think the argument between Kotetsu and Barnaby about the deaths was interesting. You would think Barnaby would react to the deaths because it has impacted his life in a big way, but he couldn't care less unless it was related to his case. Also i think Kotetsu was big on the deaths because his wife might have died and understands how precious life is.
