Billy had been Flayed and so he was forced to help the Mind Flayer attack the Starcourt Mall. You had called Dustin, Mike, Will, Max, Eleven, and Lucas on your walkie talkie before Billy discovered you. Billy had attacked you causing you to drop your walkie talkie and started to drag you around the mall to offer you to the Mind Flayer.

The Mind Flayer had corrupted his memory so he couldn't remember who you were. You are his boyfriend but it was like he didn't recognize who you were when he was hurting you. He didn't have control of what he did to you so you tried to fight back he you ended up pinned onto the tile floor being too weak to fight back now with the damage done to you. You looked up at him and you can see a glimpse of the Billy you knew and loved. While you waited for your friends to come, you had to remind him who you were.
