The threat was one they would follow through with, and Thorin knew that. All members of the company came to a halt, and Kili looked to his uncle in desperation. What were they to do?
Finally, Thorin planted his sword into the ground. Kili tossed his own weapon aside, frustrated with himself for having failed to guard the ponies in the first place.

After their surrender, the trolls got to work sorting out the hostages. Dwalin, Bofur, Dori, Ori, and Nori were tied to a spit over the fire. Thorin, Kili, Fili and the others were thrown into sacks with the drawstrings tied so tightly that they had no real way to escape. Once they'd been tossed into a pile, the trolls argued how to cook the dwarves on the spit. This gave Bilbo an idea.

As best he could while in a sack, he stood. "Wait! You are making a terrible mistake."
"You can't reason with them!" Dori called. "They're half-wits!"
Bofur scoffed in response. "Half-wits? What does that make us?"
Bilbo grimaced lightly, then continued with his self made plan. “Uh, I meant with the, uh, with, uh, with the seasoning.” To his relief, this caught the attention of their captors.

“What about the seasoning?” Bert demanded, and Bilbo tried to shrug. This was not easily done while in a sack.
“Well have you smelt them? You’re going to need something stronger than sage before you
plate this lot up.” This earned him plenty of yells from the dwarves, and Gloin called him a traitor for such a remark.
Tom's beady eyes narrowed. “What do you know about cooking dwarf?”
Bert moved closer, obviously interested. “Shut up, and let the, uh, flurgaburburrahobbit talk.”
Unfortunately, Bilbo hadn't thought this far ahead. “Uh, th-­­the secret to cooking dwarf is, um­­..”
Bert leaned in to hear better. “Yes? Come on."
Bilbo was inwardly panicking; he needed to stall for time. “It’s, uh­­...”
Bert was impatient, however. “Tell us the secret.”
Bilbo closed his eyes and nodded. “Y-­­yes, [i]I’m telling you,[/i] the secret is . . . to skin them first!”
Once more, this got angry, shocked responses from different dwarves. Thorin was the only one out of them to be quiet; he seemed to understand what their burglar was up to.

The trolls started to argue again, however. Tom did not trust Bilbo's advice in this instance; what hobbit knew how to properly cook a dwarf? It was here that Bilbo caught a glimpse of Gandalf, and he felt his heart speed up. They had a chance. 
Finally, William had enough. "Nothing wrong with a bit of raw dwarf! Nice and crunchy," he grabbed Bombur up as if he weighed nothing at all, and Bombur protested and squirmed about the best he could, moments away from being eaten.

Bilbo was quick to speak up. “Not-­­not that one, he...­­he’s infected!”
Tom looked to him critically. “You what?”
Bilbo nodded, then glanced towards the others as he tried again to think clearly. “Yeah, He’s got worms in his … tubes.” This was not good enough to save the others, so he added on to his lie. "In-­­in fact they all have, they’re i-infested with parasites. It’s a terrible business; I wouldn’t risk it, I really wouldn’t.”

Kili's eyes widened a bit, and he could scarcely believe his ears. This was outlandish. "We don't have parasites! YOU have parasites!" Comebacks were not his specialty. The rest of the dwarves claimed that Bilbo was a fool. Bilbo rolled his
eyes as they messed up his plan. 
Finally, Thorin kicked the others, and all was quiet. Kili now understood as well. “Mine are the biggest parasites!" He sounded quite childish, his fear getting the better of him. Even if they did make it out alive, he still had to face Thorin. "I’ve got huge parasites!”
