you had called the police on your abusive mother

The police arrived and knocked on the door, she didn't answer and wouldn't let you, so they kicked open the door.

Your boyfriend, he didn't realize it was you who called, and you hadn't remembered he was an officer

His eyes widened "Babe?- Um.." he turned to your mother "Ma'am you have to come with us." He said trying to cover what he said

M: "No! What the hell?? Why are you here?!"
