Kili held on, his heart pounding in his chest. The giant eagles, his godmother...they were all flying. This should have been a sight to marvel at, but he was too concerned for Thorin to truly appreciate what was happening.  
Kili overheard Fili's shout to their uncle, and could not help but fear the worst. Fili was seldom scared, and Thorin may have been worse off than he realized. 

As they reached the cliff, Kili was quick to remove himself from his godmother's back. Despite Saeril's efforts to hide her pain, Kili sensed it. "Are you alright?? You should sit down." The youngest was looking to where the bandaging would have been, and then the eagle carrying Thorin set him down.
