Hotch stared up at the door, seeing it bulge slightly from the pounding on the other side. He looked down to a crying Emily, her body shaking. "Emily, I want you to go into Jack's room and stay there until I come and get you. Ok?"

"No, no, no. I'm not leaving you out here with him."

Hotch shook his head and helped her up, bringing her down the hallway. "Hotch stop it!"

"Emily!"

Emily looked up at her boss and began crying again, her hands plastered to his chest. "I don't want him to hurt you. Please just tell him I'm not here."

Hotch pressed a kiss to the top of Emily's head before opening Jack's door. "It'll be ok. Alright? Just go in here and sleep with Jack. I'm not letting him hurt you again, Emily."

Billy smiled to himself as the door began to open, but scowled at the man who appeared. "Where's Emily?"

Hotch shook his head, holding the door open just a crack, hiding the rest of the apartment from Billy's view. "I have no idea. Shouldn't you know?"

"Apparently I don't. But I sure as hell know that you know where she is. So you tell me, or your son will be woken. And may I say, not in a pleasant way Aaron Hotchner."

Hotch's eyes hardened as Billy's grin grew. "You're going nowhere near my son, Billy. Get away from my house and leave Emily alone."

"She's there I know she is!"

"Why would she even come here?"

"Because you're fucking her!"

Hotch's eyes grew wide as he flung the door open, showing Billy his clenching fists. "Get away from me, my son, my house and my subordinate. I don't appreciate being woken up in the middle of the night to hear this bullshit."

Just as Hotch began to close the door, he was pushed inside, and fell into his coffee table.

Billy grinned wickedly as he slammed the door shut, and grabbing Hotch by the collar of his shirt. "Tell me where she is."

"Go to hell."

That won Hotch a blow to the stomach, causing him to wince as he was pulled to his feet. Billy's face invaded his, the smell of alcohol wafting his nose. "Are you really protecting her?"

Hotch nodded before gaining his breath back, pushing Billy off of him. "I will protect anyone I love, especially from people like you."

"Meaning?"

"An arrogant, conceded, abusive jackass!"

Billy shook his head before charging at Hotch, knocking him to the floor.

Emily quietly stepped out of Jack's room, leaving the sleeping boy alone. She walked into the living room, and her eyes immediately widened as ran over to the two men. "Billy stop it! Get off of him, please!"

Billy stood, dragging a coughing Hotch up with him. "Tell her what you said to me, bud."

Hotch landed a punch to Billy's jaw, causing him to stumble back. "What I told you? I told you to leave and go to hell!"

Emily held Billy back when he made a move to charge back at Hotch. "Billy please stop it."

"Why are you here?"

She shook her head, pain rushing through her arms as he grabbed a hold of it. "I came to drop Jack off."

"You should have been home by now!"

Emily's eyes widened in fear as she nodded her head. "I know Billy, and I'm so-"

"Don't say another word Emily."

Both Emily and Billy turned their attention to Hotch, who grabbed Emily's arm and pulled her out of Billy's grasp. He held her head against his chest as she grabbed onto his hips. "Billy I think you should leave."

"SHE'S MY GIRLFRIEND!"

Emily shook her head as Billy tried to grab for her. "Please Billy, just leave me alone. I wanna stay with Hotch."

Billy grabbed Emily's arm, but didn't try pulling her. "You're my girlfriend, and you're coming home with me."

"Please Billy-"

"COME WITH ME."

Hotch shoved Billy towards the door, his back slamming into it. "Maybe you didn't hear her, but I did. She wants you out, and so do I. So why don't you go and pull on some cat tails, whatever you do when you're alone."
