Alastor was injured,and you were taking care of his injuries.

But,as you were doing that, you noticed he was confused. He was a strong overlord,after all. Also a serial killer and a cannibal,so how? How did someone manage to hurt him? Noticing how he's acting, you softly sing a song in a silent volume to comfort him, you were from a modern time,differently of him who died in the 1930s. So you sang 'The Other Woman' by Lana Del Rey to him and it immediately comforted him a bit despite the fact that he was surprised.
