"Throat cutters." Fili confirmed with a nod, taking his smoking pipe out of his mouth as he spoke. "There'll be dozens of them out there."
"They strike in the wee small hours of the night when everyone's asleep." Kili added, a smirk playing on his lips. "Quick and quiet, no screams...just lots of blood." 
The twins exchanged a glance with one another and began to snigger to themselves.

"You think that's funny do you?" Thorin snapped at them from where he stood overlooking the road ahead, glaring over his shoulder at his nephews. "You think a night raid by Orcs is a joke?"
"Sorry uncle, we didn't mean anything by it..." Kili apologised meekly.
