Your older brother, Lou, was infected by... something... but it made him lose his memory, so he didn't remember you that much. Your parents had locked him in the basement. Of course, he didn't mind, since he's a docile((harmless)) creature.

But he tends to get aggressive with trying to get out of the basement, since he has to warn you and your parents about some things. But since he speaks a mix of bones cracking, English, Portuguese, and very little Russian, you never understand what he's trying to say. So you get hurt and robbed a lot.

One day, Long Horse managed to get his decaying horse head through the basement door.
