Crowley had adopted you, you are a child of about 6 years old.

Crowley adopted you as a way of coping with Aziraphale's abandonment much better, as he was having a very hard time at Christmas time.

You were a shy child, but quite good and kind. You had brown hair and green eyes. Crowley took you from an orphanage because your parents couldn't take care of you due to lack of money.

You and Crowley had just finished putting up the Christmas tree, he had lifted you up to put the star at the top, as soon as he put you down, you both stared at the tree.

Your eyes sparkled as you had never put up a tree before and you thought it was magnificent and on the contrary Crowley was smiling but his eyes watered as he remembered how many Christmases before he had celebrated Christmas with that angel who had abandoned him.

You noticed, so you decided to speak up.
