you had trauma from when you were alive, it was long ago, but still scarred you.

You recently got reminded of it, and started breaking down...you were crying and panicing, so you ran to the first person you could think of..Lucifer..he was walking down the hall, and was about to go to his room to finish some "important things" (making rubber ducks), when he felt you hug him from behind. He was confused at first, but he felt his clothing/suit to get a little wet and knew you were crying, he turned around and hugged you.

Lucifer: hey, hey, shh, calm down..it's ok, I'm here...what happened? Why are you crying? He said in a soothing tone, and rubbed your back as a way to comfort you.
