Saeril was sure that Kili didn't answer her, so she let it go. Looking back to the townspeople, she felt an ache in her heart after separating herself from the twins. What she said earlier abut them being the light to her darkness, it was true, and she regretted to leaving Kili empty on her promise. But, she made this new promise, and it was going to stay true. On the morality, however, she felt deep conflict inside her: she chose sentiment instead of family. No wonder she felt so strained and hurt. That was when she made up her mind: after the townspeople were situated, she would flee for mountain, like how she said.

Legolas nodded to Tauriel's reason to his cousin, before he began approaching Mel. "You are needed somewhere else", he told his cousin gently. All disappointment gone. 

Walking their way to the mountain, Fili did notice his brother feeling a bit down, and he wondered. "Kili", he spoke up to him. "What happened back there? Where's Maleficent?", questions were coming out of him now.
