Lou had been in a few battles alongside with Cane and the other, thus he knew the brutality and how hard it was to kill those creatures, who were infused by dark magic. They were so vicious and would get on your nerves, because no matter how you hurt them, they wouldn't feel pain and even when you cut off one of their limbs, they would act like nothing happened, unless you severed their heads.
Therefore, Lou didn't want to fight against them, especially if they were being outnumbered now if they were really going to be attacked.
For heaven's sake! He was not a fighter! He was a merchant!
"Be quiet and follow me," Cane said, as he continued to walk again, but then he took off his cloak, which made Lou was on alert.
"What?! What now? Why are you taking off your cloak?!" Lou stopped following him. "Put it on again!"
