Excellent dilema for Arthur!
If I was feeling really dramatic I'd ask, "What will he be when he leaves the room, a coward or a corpse?"
However, I will settle for substituting 'coward' for 'killer'. Love Arthur!
A great chapter, with a lot of tension seeing the conversation between Arthur and Mikey seen by the boss, and then Arthur putting his foot in it like that.
All I'd say is that with all the focus on the sligs, the mudokon sections seem a bit superfluous, and might have done better in their own chapter. And that we've seen that conversation three times now in the course of three chapters, which works since this story is updated occasionally, but if you were reading it like a book it'd probably get boring.
still, very good. I look forward to seeing where this'll lead.
