"I was drunk. I'm sorry Callie. It didn't mean anything." George looked down at his feet, he was afraid to look at Callie, afraid to see the pain I her eyes. He was waiting for the yelling to start, but it didn't come. Instead Callie pushed past him, she slammed the door to the locker-room and started storming up the corridors of the hospital.

Callie was mad, she was raging mad. But she wasn't surprised. She knew this was coming, she saw it coming from a mile away but she didn't think it would actually happen. She thought George would stop it. She knew Izzie was jealous, she knew she could be a conniving bitch but she didn't think she would stoop this low. She got him drunk, she took advantage of him.

Izzie sat on the beds in the basement with Meredith. They were shearing a patient and were trying to work out what was wrong with them. Callie heard them before she saw them. She pushed the sleeves of her shirt up and took a deep breath. She didn't try and compose herself she didn't want to be composed for this.

She walked straight up to Izzie, she grabbed her arm and yanked her up. She looked Izzie straight in the eyes punched her hard across the face.

"Callie!" Meredith yelled standing up. Izzie just stood there completely stunned. She hadn't been expecting that. "What's going on?"

Callie turned to Meredith and glared. "Stay out of this Meredith." She said before turning back to Izzie and hitting her again.

Blood started running from Izzie's nose but she didn't fight back, not in that instant. Meredith tried to step in between them. But they were both stronger than her; Callie pushed her aside and started advancing on Izzie again.

Izzie put her arm up to protect her face as Callie made another swing at her. From the side Meredith started yelling at her. "Callie stop hitting her! Use your words!"

Callie stopped throwing punches. She got right up in Izzie's face and started yelling at her instead.

"You conniving, manipulating, bitch. I know you have issues; I know you've been through some shit. I've been letting the way you've been acting slide but not anymore."

She grabbed Izzie arm and pulled it away from her face. She tried to use her free hand to hit her again but Izzie was ready this time, she grabbed Callie's arm with her other hand. The two women stood staring at each other eyes locked.

"I know George is your friend. He's your friend. I'm his wife. You need to get that through your head. He doesn't want you."

That made Izzie mad. She'd been taking a beating, she was willing to accept that what she'd done was wrong but that made her mad. She pulled her arm free of Callie's and tried to lay a punch into her.

"George was my friend a long time before he knew you. You're not his family. We are."

Meredith still stood at the side yelling at them to stop, to use words.

"Yeah Izzie, use your words. Tell Meredith here what you did." Callie yelled while deflecting punches from Izzie.

Izzie didn't respond but she let her guard down just enough for Callie to get the upper hand in the fight again. Callie whipped Izzie's arm hard around her back and kicked her in the knees. Izzie went falling to the floor and Callie griped onto her tighter.

"Tell her. Tell Meredith what you did." Callie yelled. "Everyone won't be oh poor Izzie anymore. Tell her."

Izzie didn't respond. She kept twisting to try and free herself from Callie's grasp. But Callie held her tighter, kept twisting her arm back further. Then over all the screaming there was a loud crack. Everyone was silent for a split second and then Izzie started screaming.
