The whispers reached you before you even got through the front door.
You'd been at work with Jason Carver, you both worked at the local diner, when Billy started texting. Blowing up your phone. He was clearly drunk by the way he texted, but he kept demanding to know what you were doing with Jason. And 'working' hadn't satisfied him. Eventually you gave a bullshit excuse to leave early because the constant buzzing of your phone was driving you insane.
As soon as you pulled up to Tommy's house, you heard rumors from the other Hawkins kids. Kids chugging solo cups and talking about "Hargrove's keg stand". Nothing new, Billy was the King of Hawkins High for a reason. But then the rumors got worse.
"Heard Tommy gave him something else with the beer." "Joey said Hargrove's pukin' in the bathroom, no way!" "I swear I saw Billy pissing on himself, he's tooootally smashed."
You couldn't tell if you were angry at Billy for blowing up your phone thinking you were cheating, or if you were worried about how plastered he was. The bathroom door creaked as you pushed it open slowly. Sure enough, Billy was passed out with his cheek resting against the toilet seat with a dark wet spot across his jeans.
