You slowly approach her. As you get closer, you see that she must be freezing cold - she's shaking, and her skin is an unnatural blue color.
LUKE
Are you alright? How long have you been up here?
GIRL
Ha-Have you... seen my brother?
LUKE
I haven't seen anyone in here but you. Are you hurt?
Your response makes her press her face even further into her arms.
GIRL
He's missing... Have you seen my brother?
LUKE
Um, hey... how about we get out of here, and get you taken care of, and we can look for him together?
You rub her back, both to try to soothe her and to try to feel for any broken bones. She's icey to the touch.
