Being stopped by Thorin, didn't stop Fili, unfortunately. All his eldest nephew DD was glare at his uncle, and yank his arm away from his grip. Walking towards Kili, he stood next to him, like he always did during their youth. 

Back in the Masters house, Bofur is passed out drunk under a table when he hears trumpets. "By my beard, is that the time!?", he shouted with slurred speech before he rises until banging his head on the table. He then rushes out to join the dwarves on the dock. "Wait!"

"Go now with our good will. And may your return bring fortune to all!", the Master announces before the crowd cheers with the company setting off on the barge down the lake. At the same time, Bofur pushes through the crowd, but when he reaches the dock, he sees the rest of the company has left, and is too far down the lake for him to reach. While this was happening, Saeril and Yavanna stayed by Kili and Fili, as they watched the boat float away. 

"I can't believe he would just leave us like that!", Fili growled angrily. Bofur looked to the side, hearing Fili's voice and smiled. "Oh, did you all miss the boat as well?"

"Aye, we have. We'll need to get this one indoors", Oin was grateful that Fili and the two she-elves showed up. Kili's condition hadn't stopped him from being stubborn, and he doubted he would have been allowed to get very far in tending to his injury.

"Kili?", Saeril heard Fili say, as soon as the blonde felt his brother's weight give out next to him. "Kili!?", Kili looked like he was about to pass out, having to almost fall on the spot. Hurrying to catch him, and before he could fall to the ground, the elder she-elf cradled him. Moving his ebony black hair from his face, he was in pain. [i]Please, not now[/i], she thought to herself. "Come on", she told the others as she held Kili in her arms, carrying him closely against her chest.
