I'm watching you. - Wait, What? (Supernatural / Lucifer)

Their downfall

For luciferstempest ♥️
Thank you for kicking my ass so I update my luci fanatic friend!

Sitting in the basement Grace sighed and slowly placed all of her fathers clothes in the machine again. She carefully took one piece after the other with only her finger tips not allowing the fabric to touch her burned skin. There hadn't even been a moment to clean her wounds and she mentally made a reminder to do so once her family was in bed. Once all of the clothes were in the machine she started it and sat on the stairs not exactly keen on seeing the others again already. And that's when she heard the weird sounds. Thinking it was the washing machine she walked up to it but was quick to realize it wasn't. The sound came from upstairs. Her eyes widened and she ran towards the stairs hiding under them. Her family was armed, but she wasn't! She didn't even know how to fight!
"Fuck... fuck... fuck...", she whispered to herself before holding her hand in front of her mouth when the door opened and light fell into the basement.
"No one down here.", she heard an unfamiliar voice and let out a breath once the door had been closed again.
"Ts Ts Ts... that easy to convince?", she heard a voice behind herself and turned around with wide eyes. Debating whether to scream or not she froze in place and just stared at the stranger.
"Well, hello to you too. I just lost a bet... I guessed you'd scream.", the man tilted his head and pouted lightly.
"W-who are you? W-what do you do here?", Grace managed to whimper taking a step back finally.
"Oh sweetheart, no need to be afraid of me. If I wanted to kill you right here you'd already be dead. Name is Lucifer. And what is yours?", the stranger, no Lucifer asked and she shivered at his voice.
"G-Grace...", she admitted after a while figuring she couldn't ignore him. "L-lucifer as in... the... the fallen angel?"
"Just that one sweetheart. Now yet another thing I wouldn't have guessed you'd say.", he spoke and took a step towards her. "Thought you'd say the devil. Seeing as I just killed your remaining family.", he shrugged and her eyes got even wider.
"You... did? Why?", Grace frowned not even particularly sad about that, but more confused. Why would her father and brothers strike the attention of Lucifer? Although he couldn't really be Lucifer of course.
"They killed my favorite demon. It's just fair to kill them. Originally I wanted to torture you and have them watch, but they already do that daily, or did, so it wouldn't have been fun.", the fallen angel shrugged again and then smiled.
"Demon?", the girl tilted her head confused. "Demons don't exist. Neither do angels. You're just a psychopath."
"Oh sweetheart. They kept you locked away hm? Come on, let's go.", he smiled and reached his hand out to hers and out of some strange reason she took it and let him lead her outside, past the bodies of her two brothers and father, out of the house for the first time since her mothers death 7 years ago, out into a dangerous world she knew nothing about and before she could blink the whole scenery changed and she was in a dark room with a throne in the middle.
"Well sweetheart, come sit with me and I'll tell you a few stories.", Lucifer spoke and patted his leg for her to sit what she did, still too confused from the realization that angels did exist, to even bother.
