It may be dark, but Anna can feel everything worth noting. The tenseness of Elsa's shoulders, and the small shiver she gives at being touched. She seems so small in Anna's arms. As soon as they pull away, her own cross protectively across her chest.
"Do you wanna maybe get a coffee? Or a hot chocolate, considering the time?" Anna asks softly.
Elsa looks at her for a second, before smiling and nodding. And, it isn't a little, tentative smile. It fills her whole face, and Anna notices for the first time... just how beautiful she is.
