For once, Thorin was in agreement with Gandalf. They were outnumbered and tiring fast. "Quickly, all of you! Go, go, go!” 
Mentally, he counted each dwarf and Bilbo as they passed him by. The last thing he wanted was for one to be left by mistake. Nearly everyone had made it, and Kili had promised to follow Fili, but when he saw that his uncle had remained, he stayed as well. 
Stubborn as ever, Kili wasn't budging from his spot in the clearing. The youngest shot at another oncoming warg, but his efforts would not be enough. 
"Kili! Run!" Thorin left no room for argument in his voice; now was the time to follow orders.

Kili backed up a few paces, then finally turned to run. With his heavy coat and weaponry, he was not as swift as he would have normally been, and at the last moment he slid to the opening in the rock formation, only to tumble to the bottom right next to his brother and burglar. "Fili!" It was a relief to see him in one piece, but his heart sank when he realized that someone was still missing. "Where's Delva?!"

At that, Thorin arrived to safety as well. An Elven horn sounded, and the sounds of battle continued on. Everyone fell silent, and one of the orcs fell into the cavern after being shot through the skull with an arrow. 
Frowning, Thorin ripped the arrow from the corpse, then threw it aside in disgust once he recognized its make. "[i]Elves.[/i]"
