It was a favourite pastime of his, to watch. He greatly enjoyed watching people live out their lives. Even if they had no idea that he was watching. He had his visitor duties of course - getting rid of FEMA, creating new brothers and sisters under the cover of night- but he knew when he could get away with simply watching.
He could vaguely remember, sometime in his human childhood, his mother telling him not to play with his food. However, it was always more fun that way, wasn't it? He liked it when his prey was scared. It made the chase more fun.
His fascination with you was a little bit more difficult to explain.
Normally, he would simply have given up by now. There was no reason for him to keep hunting you, when there's so many other homeowners around. Some, no doubt, were alone in their homes. But something about you kept him from giving up completely.
He liked to watch you from far away. Liked to watch your silhouette move past the darkened windows. He liked the way he could smell the fear rolling off you whenever you spoke to him through your door.
Originally, he hadn't wanted to do much more than hurt you like he had everyone else.
But something was different about you. And he so terribly wanted to know what that was. What better way would to do that than to turn you into a visitor. Have you by his side for eternity, or until the world finally ended like a humans were saying it was going to.
His most primary weapon was his voice. He knew full well that his was a soothing one. If one weren't looking at him it might be easy to mistake him for someone who one could trust. He knew you were growing tired with the state of the world. Lonely.
He didn't come every night. Not at first. But that didn't mean that his visits weren't often.
You were so tired of being alone. So tired of being afraid. He just wanted you to see that he could fix that for you so long as you would come outside and allow him to free you from your humanity, from all weaknesses. He understood why you were hesitant. But he was wearing you down.
And then the night he'd been waiting for came. You finally cracked under the crushing pressure. You were alone in that house. In his excitement he accidentally ripped your door off its hinges. He politely set it to the side and stepped in, ghastly features curved up into a smile.
"Are you lonely, my dear?" His voice was soft, soothing. He took the shotgun from your limp hold. Then, he leaned down, nuzzling you like a nightmarish cat.
