"Arizona, Arizona, can you hear me? Stay with us, Arizona, ARIZONA." Callie couldn't be a doctor right now, her wife was laid unconscious on the wet floor for the elevator, and Callie could feel the water seeping into her scrub pants. Callie looked down and saw liquid was staining her lab coat. Her eyes widened in terror, it wasn't water on the floor of the elevator; it was blood. But where was it coming from?

Callie checked Arizona frantically, trying to figure out where the bleeding was coming from. Then she found it. Her leg, it looked like a jagged line made my some kind of blade, that went round the entire perimeter , cutting straight through her femoral artery, "Someone get a gurney, now! Well don't freaking stand there. NOW." Callie yelled at one of the interns.

"What the hell? What happened to her?" Callie heard from behind her, the voice was familiar but in the mist of all the chaos going on in the small space it wasn't until she turned her head to see the familiar voice was Karev's.

"I don't know, Karev. I just found her like this, here; help me get her up on to the gurney. She's hypothermic, her pupils are dilated, and her purse is weak, she's lost a lot of blood, gods know long she's been up there." Callie said her voice breaking as she tried to hold back the tears. Crying wasn't going to help her wife right now, right now she had to be a doctor. "When did you last see her?" Callie asks turning to Karev.

"I don't know, maybe like 2 hours ago, maybe 3?" he replied.

"You don't know?! Think dammit, Karev, its important!"

"We need to get her down to trauma now, someone page Hunt, STAT!" Callie shouted to one of the interns as they wheeled Arizona as fast as they could to the Trauma department. Callie's mind was racing, what the hell happened up on that roof? And more importantly what was she doing up there in the first place.

Just as Karev and Torres wheeled her into a Trauma bay Chief Hunt arrived, "What have we got here, Dr. Torres?" Hunt asked before he could see the patient was Arizona, "Oh God. What happened? Where was she? Callie I need you to talk to me. I need you to tell me what happened." Hunt said to Torres. Callie stood there in the trauma bay staring down at her wife laid unconscious on the gurney. She should have known something was wrong, Arizona had been different for weeks, but Callie hadn't pushed, she wanted Arizona to come to her in her own time. Guilt plagued her, what sort of person doesn't notice their wife's on the verge of a breakdown? Callie was frozen on the spot, she could hear the voices of Karev and Hunt in the distance but she couldn't register what they were saying.

"TORRES! " Hunt yelled, his voice rose.

"Get her out of her Karev, she can't be in here, that's her wife on the table. Get her out of here and page Kepner to OR 2. We need to get Robbins up to an OR now, we won't have time to scrub, she's already lost too much blood." He paused, "Ring path, we need three units of O Neg in OR 2. Karev, you stay with Torres, we're going up now. Come on people, MOVE." Owen commanded as they headed up to OR 2.

Karev took Torres aside to one of the vacant trauma rooms, Callie followed him, silent the whole time, she couldn't speak. Words failed her. She had done this. This was her fault.

"Torres, can you hear me. It's going to be okay. Hunt's got this. Arizona is going to be okay. Do you want me to get you anything? Coffee, maybe?" Karev asked, he didn't know what to say. It was easy when it was a patient's family, it wasn't anything personal, it was just doing your job. But this was Callie, his friend, his colleague, his mentor's wife. Karev wanted to believe the words he was saying but doubt niggled at him, what if she wasn't okay? She'd sliced through her femoral artery; she'd lost a lot of blood. God there was so much blood.

Finally the silence between them broke and Callie began to speak,

"This was my fault. I should have noticed, I mean, I did notice, but I didn't say anything. She's been like a frightened deer all year, I've been walking on egg shells so scared to say anything that might set her off, so I kept quiet. Things were getting better. I thought they were, so I thought I'd let her come to me, you know? And now she's through there in probably bleeding to death because I didn't do anything. Because I was so freaking concerned about upsetting her, and now she might die in there, Karev, she might die… oh god." Callie paused, tears flooding her eyes and choking her throat.

"I can't lose her, not again…I can't…"

It felt like hours since Hunt had rushed Arizona into surgery, Callie's eyes were fixed on the clock, time seemed to have stopped. Then she saw Hunt coming towards her, she tried to read his face, but his scrub mask covered up any hint of whether it was good or bad news. "Please be okay…please be okay" Callie whispered to herself.

"Callie, we done everything we could, she had lost so much blood…" Owen paused. "But-" he was interrupted by Callie collapsing to the floor sobbing before he could finish.

"Torres, we managed to close up her femoral artery. There was a lot of muscle damage, but she's stable. Kepner's taking her up to the ICU right now. Come on, I'll take you up there now." Owen finished crouched down on the floor with Callie.
