Taking the cup from the girl, Shalan let a whisper of a smile cross her lips before she looked to the girl's father again. He was reading her. Estimating her strength and gauging her abilities. His eyes on her blade made her nervous, but she refrained from grasping the hilt in caution. It may be taken as a sign of hostility. 
Her wariness faded slightly when he smiled at his child. Shalan felt grateful for the girl's presence. She seemed to relax the air quite well. Without her, Shalan and Keiro may have simply stood and stared all day.

"I'm grateful for the offer." She said slowly when he looked to her again. "A bed is something I have missed for a while. And a meal," Shalan tiled her head slightly, glancing at her pack. Inside was a few pieces of salted meat from a raccoon she'd managed to snare a few nights back. "A meal sounds nearly as amazing." 
While not entirely warmed up to the man just yet, Shalan offered a more antural, relaxed smile. "My name is Shalan." She raised the cup and drank, feeling the cool water fill her empty stomach. 

"Thank you for your kindness. It is rare to come across. And, pardon if I am a bit rude, but may I sleep?" Shalan gave Korra a soft look. "Your brave girl woke me, and I haven't had a good rest in days."
