Too late: Sarah walks in

“Hey Sam, why haven’t you-” Sam heard her sister’s voice die off mid sentence. Somehow, Sam hadn’t noticed the door opening. Now she stood in front of her sister like a deer in headlights.

At first, Sarah looked like she was about to tell Sam off, but as her gaze drifted lower, her mouth dropped. “Wha-who are you?!”

Sarah shrieked as she scrambled backward, reaching for something to defend herself with- as if Sam was going to try to hurt her.

Sam quickly threw her hands up placatingly, hoping to calm Sarah. “Wait! It’s not what it looks like! I’m Sam!”
