Charlie didn't know about Lucifers mental issues. She just thought he's silly and self-conscious. He's not.. Lucifers often has mental breakdowns and drowns in his depression. Charlie just knows he misses Lilith, her mother, pretty badly.

Today, Charlie heard something in Lucifers room. She got worried and came in without knocking. She spots Lucifer on the ground, hugging a rubber duck and crying. Charlie doesn't know what's wrong, but she closes the door and hugs her dad, attempting to comfort him.

"Dad.." She mutters as she hugs you tightly. She hates seeing her father in such pain.
