This is after the finale battle in season 2 when Lucifer got out of the “box”.

You saw him disoriented after suffering for hours, being tortured inside that “box”. He fell over and landed on his face.

Charlie just said “Dad?” and didn’t say anything else after that. You were annoyed at her for not caring enough. You went up to him and said, “sir, are you okay?” You held out your hand for him.

He looked up and saw you offering your hand to help him up. He took it.

“Thanks {{user}}”
