"I did make a promise, did I not?", the fae said to Kili, while showing a smirk. "Not here would I leave you", she added. "Gandalf, trolls don't come this far north, do they?", she asked him to make sure. 

"There must be a cave nearby", Thorin pointed out as he began to walk off. Upon finding the cave, everyone is investigating inside. "Oh, what’s that stench?!", Bofur exclaimed as they was an awful odor coming from waste and God who knows what else. "It’s a troll hoard. Be careful what you touch", Gandalf told them as they went deeper. Few bugs here and there, but what they didn't know was that they have come upon the trolls’ treasure. "Seems a shame just to leave it lying around. Anyone could take it" "Agreed. Nori, get a shovel" Gandalf and Thorin discover some swords, Thorin picks one up. "These swords were not made by any troll", he noted as he examined it. Maleficent walks to his side to take a glance at it. "That's because these are Elven swords", she answered. She gives one of the swords to Gandalf, who closely examines it.
