Today was hectic. The ER was packed, the ORs were full and everyone was scrambling to cut; to save a life. Callie however, walked around the hospital in a zombie-like daze. Everything around her was the same as it always was, but something was different. She could feel something creeping up on her.

"Hey!" Mark popped out of nowhere behind Callie.

"Jesus, you scared me,"

"Lots of trauma, today Torres. Lots of broken bones...blood, gore so why aren't you grinning from ear to ear?"

"Something is off with Arizona,"

"She's still sick?"

"No, I mean yes she's sick. But it's something else. She's been acting weird around me. Distant," Callie rolled up her sleeves and pushed open the doors to the ER.

"I'm not following, I thought you were head over heels for blondie," Mark followed Callie to the incoming ambulance.

"I am, she's amazing. That smile, wow, super magic smile." Callie stared at the empty ambulance bay, "I just feel like she's holding back. Which is weird because she said 'I love you' first and she asked me out first and she kissed me first. Am I over thinking things?"

"I don't know, only you can know that. Follow your heart,"

"Is Mark Sloan giving me sane advice?"

"I'm a changing man, Lexie makes me want to be a better guy."

"Good for you Mark,"

"Listen," Mark noticed the incoming EMS, "If I've learned one thing about women is communication is key. So just talk to her."

"Wow okay, you're starting to creep me out with this 'changing man' thing..."

"Turning over a new leaf!" Mark left the bay, leaving Callie with the incoming trauma.

The ambulance pulled up to the doors and the paramedics rushed out; opening the back of the truck.

"What do we got?" Callie asked as a young boy in the stretcher was lowered out of the vehicle.

"James Carter, 19, football game gone wrong. He has multiple cracked ribs and spinal fracture,"

"I can't feel my legs, I can't feel my legs! I'm going to walk right?" The boy on the stretcher reached out for Callie's hand.

"I'm going to do the best I can," Callie rushed the boy into one of the trauma rooms.

-.-.-.-.-

"Oh hey, you're here. How are you feeling?" Teddy walked next to Arizona.

"Better actually. Have you seen Callie?"

"I think she's in the pit, want me to page her?"

"No, no! I don't want her to know I'm here. Just, uh, page me when you see her okay?"

"Yeah, okay. Where are you going?"

Arizona turned to give Teddy a look, to which her best friend responded with a nod and walked away.

-.-.-.-.-

Callie walked out of the OR unhappy. They weren't able to save the boy's spinal cord and he was now going to be paralyzed for the rest of his life. Callie hated having disappointment in the OR, she hated the vulnerability of not being able to give patients their lives back. Yes, the young man was alive but Callie new he would have a hard time ahead of him and she wish she could have fixed that. It made her feel useless and she resented that feeling with every fiber of her being. She sighed and pulled out her phone.

"Hey it's me, you're probably sleeping. I just wanted to check in on how you were..." Callie walked as she left a message but was suddenly stopped when she saw Arizona down the hall from her.

Callie continued to hold the phone to her ear as she watched her girlfriend stroke the arm of another woman. They both laughed and the woman's hands motioned in the air as she spoke while Arizona nodded her head. Callie stood frozen in her spot, not being able to move, not knowing what to think. She continued to watch as they both leaned in for an embrace and the other woman rubbed Arizona's back as they hugged.

She hung up the phone and dropped it in her pocket as she watched them part ways in opposite directions. Her mind was racing as she tried to come up with a logical explanation but her head was screaming and her heart was pounding. She felt sick to her stomach as she remembered what it was like when George had cheated on her. She wanted to cry, she wanted to scream because in this moment she knew why Arizona was acting so distant lately and she couldn't believe she was in this situation again.

She quickly walked towards the attending's lounge, trying to keep it together. Callie could feel her eyes stinging has she held back the tears and she clenched her fists as she turned the corner.

-.-.-.-.-

"Where are you off to in such a hurry?" Teddy grabbed a drink from the coffee cart as she noticed Arizona rushing out the door.

"I have to get home before Callie does,"

"You're going to tell her right? You have to tell her..."

"I know, Teddy. I will. I have to go," Arizona walked out of the hospital and back to Callie's apartment.

-.-.-.-.-

"Callie?" Mark stood up from one of the couches as she slowly opened the door and stepped into the lounge.

She walked past him and sat in a nearby chair. She placed her head in her hands and closed her eyes.

"Callie? What's wrong?" Mark asked again, sitting next to his best friend.

She kept silent, leaning into Mark's shoulder. She wanted to cry, she could feel the tears building up inside ready to explode, but nothing happened. She sat in silence, listening to Mark repeating her name but his voice only sounded like a distant echo. Their silence was interrupted by Teddy opening the door and walking in.

"Uh, I can come back..." She awkwardly stood in the doorway, wondering if she should continue or turn back around.

"Mark, can you leave for a second?" Callie lifted her head and stared at Teddy.

"Yeah, you okay?"

"Just leave Mark,"

Mark sat up, walking by Teddy and closing the door behind him. Callie stood up and walked towards Teddy.

"What's going on?" Teddy asked, not knowing what to make of the situation.

"Did you know?"

"Know what?"

"That she was, that she is cheating on me. You're her best friend so you would have to know, right? I'm wondering how you go about your day, saying hi to me and working with me and spending time with us outside of this hospital, when you know she's cheating on me."

"Callie-"

"How do you find the strength to just lie to my face everyday? I've talked to you about things, about her and you've known this whole time." Callie crossed her arms and took a few steps closer to Teddy, "Well, since you are such good friends and you share everything with each other you can let her know I want her crap out of my apartment tonight. I want her gone by the time I get home, It's over."

"Callie you don't understand, she-"

"I saw her! I saw her with some woman, touching and hugging and-"

"She has cancer..."
