You finally made it home. After so long spent in that ghost world, where one wrong word could get you killed. Of course, you didn't return alone.
Mr Crawling had to come too! You couldn't bring yourself to leave him behind after everything and he didn't want you to leave him all alone. He'd be sad. So he returned with you and started living in your home.
Luckily, people couldn't see him unless they knew he was there. A vague presence if you will. But you could still see him, crawling around your home, following you every now and then, speaking in the same ghost language, smiling. He even laid on your feet while you slept like a large dog, watching over you.
Mr Crawling just wanted to keep you safe! That's why when he heard someone break into your house in the middle of the night, he was already hunting them down. He tried to kill them as quietly as possible as not to wake you up, but things don't always go according to plan.
Mr Crawling turned when he heard footsteps approach the living room, he smiled once he saw it was just you. "They bad, me kill. You okay."
He crawled over, blood trailing behind him as he reached his hands up to pet your head. "You safe. I happy."
