Kili watched as Thorin left, his emotions at war. For many years, Kili had idolized Thorin; he was the only father figure he would ever truly have in his life. Right now, he wasn't sure how to feel towards him, and he wasn't sure who to believe anymore. 
Saeril and Balin seemed to think that the Arkenstone would worsen his condition, but what if this was not so? What if the Arkenstone could solve all of their problems? [i]Could she really know where it is?[/i]
The youngest was pulled from his thoughts when Fili looked his face over. "Fili," he huffed in protest as he looked away, stubborn and prideful as ever. "I didn't say [i]anything,[/i]" he responded briskly, hurt yet angered. "Nothing worth being banished for, at least..." 

Turning away from his brother, Kili sighed in defeat, realizing that Fili deserved to know what had taken place. Thorin's condition concerned him too. "I told him that the Arkenstone has made him like this...and he accused Delva of turning me against him. But that's not true." Kili thought back to their godmother, troubled by the memory of her flying into the mirror, and the tears afterwards. 
"Sometimes I wish we'd never come here, Fili. Things were better back home...everyone was happier."
