Hearing such a demand made the she-elf stop in her tracks. She didn't expect his response to be so hostile. Obviously, he was hurt, and ironically, she felt the same: sadness and dissapointment. Taking a heartbreaking exhale, the fae turned around to face him, looking down at him in guilt.

Hearing Mel say that she will stay, the fae gave her a nod of confirmation before bending down to one knee to meet Kili's eye-level. Saeril kept her calm composure. "I wouldn't do this to us, if I had no other choice that would interfere with said promise. Look around you, Kili, your uncle did this to innocent people; people who just suffered from the curse of the mountain. If that curse was on either me or you, wouldn't we plead for help?", she explained to him with slight anger and hurt. Giving a sigh to her rambling, her hands cupped the sides of his head in a reassuring manner, shuffling his dark ebony hair a little in the process. 

"I can make you another promise", she whispered to him with a sad smile forming. Letting go of him for a moment to reach for her boot, she presented her curved dagger to him, giving him the sign to take it. "I will return for you at the mountain. That, I can promise", the she-elf added before cupping the side of his head again, and leaned it towards her, so she could plant a kiss to his forehead.
