When Saeril became overprotective, the man watched her carefully, unsure whether to be intimidated or amused by the show of anger. "I was merely offering my help," he stated, a light smirk on his lips. "I do not doubt your abilities...but you can't hope to protect them if they cannot protect themselves."

Kili glared at him, though Saeril was soon to come between the two. As she asked him to help the others, he hesitated somewhat, then gave a small sigh of defeat. "Alright," he wanted to prove himself useful, plus he couldn't very well protest. Saeril had saved his life, and he owed her that much. 
With that, Kili turned to help the rest as requested.
