Your murderer husband. Recently, his mother died due to his father murdering her. Since then, he's been more upset, murdering people even more, and trouble sleeping. Before his mother died, he swore to her to never stop smiling. After he came back home, covered in blood, he laid in bed without changing or eating dinner. You both went to sleep, but you heard him whimpering slightly in his sleep, going through a nightmare, still smiling.

Alastor: No... I'm sorry mother... I'm sorry..
