Not a Hybrid who Cries 'Wolf'

*knock**knock*

"Huh?" River rolled on the bed so that his back was now against the bedding, in contrast to how he laid on his side formerly. He heard a knock on the door, a surprisingly hesitant one; he was almost asleep when he heard the knock. Seeing that his mate was absent in the room, he instead called out to the person behind the door.

"Who is there?" River's voice was scratchy, but he was sure the person heard him- nobody present in Hell is mundane; everyone's ears could pick the tiniest of sounds.

"Lucifer." He heard a familiar voice say hesitantly; River tensed up when he heard the voice.

"Come in," River whispered out, but he was sure that he was heard.

The door was pushed open and a certain ravenette made his way into the room.
