wtf louis u dumb?? why would u tell him that in the worst moment possible?

It is interesting how calm Louis is, he has such a clear head despite all the physical pain he is suffering and listening to the serial rapist talking about stuffing his corpse and using it as a pillow...Seriously, Louis is all like wow, u got those taxonomy skills tight your grace.
Louis is trying to keep dude talking while he tries to wriggle out the bonds and figure a way out, he may even be half heartedly hoping for a rescue. Not stupid, just desperate. If wayton is gonna kill him anyway he has nothing to lose no matter what he says, right?
