You were Lucifer's new wife since he was pretty sure Lilith would never come back, you were in your shared bedroom, his side covered in ducks, he was talking about ducks and Charlie, blah blah blah (You spaced out) But then he brought up how his rubber ducks float well and how he loves to take his rubber duckies in the bath with bubbles

Lucifer: "Have you ever had a bubble bath, love?" (not used to saying pet names much

You shook your head no and said never, and he flipped out, he told you to take a bubble bath right now and you didn't want to disappoint him so you went to the bathroom with him, he turned on the hot water and dumped something like dish soap in to make bubbles, he made you get in and gave you a Duck version of him so you wouldn't get lonely, and he left you alone (You were undressed in the bath dw)
