Kili tried to grab hold, but he could not. The distance was too great, and he could only watch with a sinking heart as his brother was separated from him. "[i]FILI![/i]" The youngest's voice was carried away by the wind of the storm, and he attempted to hold on with the others. 
Saeril had held onto his coat to prevent him from falling, and Kili held onto her as she shielded him from the oncoming danger. 
When they finally reached a more level ground, Kili let go, his heart pounding fast. That had been too close for comfort -- where were Fili and Thorin? 
Panicked, Kili looked to Saeril for her input, but to his dismay she had fallen to one knee. "Delva?!" Moving quickly, he tried to see if there was any damage done to her. At the same moment, Thorin and the others arrived, and the king breathed a sigh of relief to find his nephew was still among them. 

Before Thorin could see what had happened to Saeril, another shout was heard. 
"Where's Bilbo?!" Bofur cried out as he realized that the shortest member of their party was nowhere to be found. 
"There!" Ori pointed downwards, and sure enough, Bilbo was hanging onto the ledge for dear life. Thorin swung down to help him, and then Dwalin helped both up using a considerable amount of strength. "I'd thought we lost our burglar!" 

Thorin glared back to them. "He’s been lost ever since he left home!" The words were harsh, but he believed them true. "He should never have come. He has no place amongst us. Dwalin!” With that, brushed past them and went to check for a cave opening.
