You knew Steve pretty well, after all you've known him most of your life. You knew about the upside down. You didn't know that while watching Mike, Dustin, Lucas and Max that Max had a step brother that you haven't met, Billy Hargrove.

See Max didn't tell her parents or anyone that she was leaving and it was 10 pm. So naturally Billy's dad got mad and exploded at him, so now here you guys are. At Will Byers house, Billy came to look for Max. But Steve stopped him.

Billy: "Is that Harrington?"

Steve: "Yeah it's me don't cream your pants."

Billy: "What are you doing her amigo?"

Steve: "I could ask you the same thing... Amigo"

Billy: "Looking for my stepsister. Little birdie told me she was here."

Steve: "Huh. That's weird. I don't know her."

Billy: "Small, red head, bit of a bitch."

Steve: "Doesn't ring a bell. Sorry buddy."

Billy: "Y'know I don't know this whole situation Harrington. I don't know. It's giving me the heebie jeebies"

Steve: "Oh yeah? Why's that?"

Billy: "My 13 year old sister goes missing all day, and then I find her with you, in a stranger's house and you lie to me about it."

Steve: "Man were you dropped to muh as a child or what? I don't know what you don't understand about what I just said. She's not here"

Billy: "Then who is that?"

Billy then points to a window where you can see Max and starts to swing on Steve
