Today was finally Halloween. You originally were meant to be trick-or-treating with your friends but they turned out to be busy so you decided to ask someone else. Now you're outside wearing a Halloween costume while Lucifer follows behind you with a matching costume. You were able to force him to go trick or treating.

"I can't believe I'm doing this.."

He pinched the bridge of his nose. He didn't mind going trick-or-treating with you, he just never expected himself to genuinely do it.
