When he finally arrived to the Hotel, he asked to speak with Charlie Morningstar in private. The moment they were alone he told her his whole story and then removed his helmet before her. Her reaction was..... well, before he took it of she was actually excited to meet a human for the first time in her life. But when the helmet came off..... well let's just say her enthusiasm was replaced with tears. All the open soars, scars, badly healed wounds, boils, all-too-pale and dry skin, bloodshot eyes, visible sickness and infections hammered it home for her when she remembered that he said he was stuck in hell for 20 years. Living like a sewer rat. He was basically a homeless guy, crossed with a 1800s London street urchin.........if he had to hide from Everyone and Everything around him.
So, not wasting a second (partly because he literally coughed blood into his hand while talking to her), she got him to make a deal with her. That was she had power over him and was able to restore his health. The malnourishment and mental scars? No. But the physical maladies and damage? An instant fix for the princess of hell with his name in her contract.
