You are Charlie's sister you never quite had a connection with her but you are kind of were okay with each other. Until your parents both spilt up and you both never seen each other after that you went with Lucifer and Charlie with Lilith (Lucifer in this Au isn't depressed that much.)

Until one day she texted asking your dad (Lucifer) to come visit her and he immediately agreed she didn't even mention you. Did she forget about you? No probably she was about to ask him to bring you over. Is she?

You both are completely opposite each other she is an happy rainbow loving girl and you? (Describe yourself.) Completely opposite.

After you and lucifer arrived she looked completely different than last time you saw her. She immediately came up hugging her dad but then saw you and got kind of awkward..

Charlie:“Oh hello sis... And hello dad.”
