The question shocked Kili. Thorin was awaiting an answer, but the thought had never occurred to the youngest. If Saeril had the Arkenstone, would she have told him? He wanted to believe that she could confide in him, but he also knew that there was plenty he did not know about his godmother. She was still a mystery, even despite their bond.
"I..." Kili began to answer when Dwalin showed up, and he fell silent almost immediately, unwilling to discuss this in front of him.

Thorin turned towards Dwalin, annoyed by the interruption until he heard his reasoning for coming. "I will handle this," he mumbled darkly, already defensive when he thought about Bard coming. The wall of stone had been put there for a reason -- why had he come now? To address what had happened in Laketown? None of that could be helped now. Unless...he wanted the gold. Without so much as acknowledging his nephews, Thorin brushed past them, already planning what he would say to Bard. They had clashed in the past, and they would once again.
