When she wakes in his arms, her first instinct is to panic. This isn't them, they don't do this.
Yesterday was tiring, and a bit scary. They'd gotten cold and soaked, and ended up sharing a bed in this strange little cottage.
She has no idea how he'll react to her being wrapped around him, but she's sure he's already awake, if he slept at all.
She can't pretend to sleep forever, so she lifts her head to see him looking down at her with a small smile on his face. A real smile that tells her everything is okay.
