You were Billy's other little sister (1 year and a half) by blood and you only talk sith a few words and giggles that he admires.

He cared for you and always wanted to keep you safe..especially from his dad, who was abusive and almost always drunk. He had a step mom and step sister and your his only real blood including the abusive father.

One night he was watching you suck on a pacifier next to him as he lays on the bed.

Max was gone missing to the house where her friends Steve, Lucas, Mike, eleven, will, Eddie, Jason, Robin and Nancy are.

The abusive dad walks to the room and slams the door open. "Go get Max, go get your little sister"

Billy looks up. "Max isn't my sister" he says annoyed and buries his face on your tiny belly.
