The two had only sent each other sparing glances but had yet to have a real conversation since that fateful day in the supply closet. Ever since, Arizona was giving Callie a reversal of her own treatment in the beginning of her time here. She stopped showing up to lunches, hadn't answered a single page, and Mark and Addison didn't even know how to handle her mood swings. When Alex showed up to treat their patient, Callie clenched her jaw and scoffed. Enough was enough. Callie marched up to the peds floor, her anger higher than it had ever been. Arizona had never been her friend, not really, so she didn't know why the blonde couldn't even look her in the face after their hook-up, but she could still smile at the countless ortho nurses who scrubbed in next to Callie day after day. She once told Arizona she was everywhere, and she didn't know how real that statement would turn out to be when she knew who knew that woman's body, when she knew that was working with one of Arizona's ladies of the night in every single surgery. Speaking of her faithless nurses, Callie saw Collen walk out of the very same storage closet she had last week. With an enraged grunt, Callie let her go but not without the dirtiest look she could muster. Scoffing, she swung open the door to no surprise reveal the peds surgeon who had been ignoring her pages.

"What the fuck is wrong with you?" Callie screamed, as the blonde adjusted her scrub top. Caught off guard, Arizona flinched into the shelf. Steeling herself, she turned around to face Callie, unable to even look intimidating when her lips were as swollen as they were.

"See, this…this is exactly what I expected from you. The slutty peds surgeon who fucks every woman with a heartbeat in any dingy ass fuck place," Callie steamed, "but what I didn't expect was for you to put the life of a child on the line for a cheap lay during the middle of the day." Callie's words burned into Arizona's skin, searing into the unhealed scars from last week that begged to be healed under the brunette's touch. Although right now, it felt more like Callie was rubbing thick grains of salt into each individual wound.

"I sent Alex, my student, to assist you on a procedure he has performed hundreds of times with me already. I know you think of me as some desperate girl that you can use in a closet and then brush off to go back to her girlfriend, but contrary to your belief, I would never put a child at risk," Arizona defended herself, but Callie couldn't see past the red that filled this room, a red that once signified passion between the two, capable of burning the hospital down, was now sparked in the heat of anger, and it was prepared to engulf everyone around.

Callie dug deep for anything to throw at the blonde, anything to slap the swollen lips off the woman in front of her, "Yeah, you would never put a child at risk through surgeries, huh?" Callie knew it was a low blow as soon as the words left her mouth. Every surgeon lost patients, and every surgeon had to compartmentalize, but peds surgeons were tasked with the heaviness of compartmentalizing the death of children, and Arizona right now seemed like one of the very best. Alex had even snapped at her in the beginning of their time together for similar behavior. She expected Arizona to lash out at her, Callie wanted the fight. No, she needed to fight with Arizona because then at least she had her in some capacity, but Arizona instead looked down at her feet and shuffled out of the closet. Callie threw one of bins to the floor, ignoring the gauze that rolled out.

"Jesus can someone please get Torres off my back," Alex muttered at the lunch table with Meredith, Cristina, and Lexie. Cristina leaned over his shoulder, catching the fire in her roommate's glare and gulped.

"You're so screwed," Cristina said, immediately removing herself from Callie's view to avoid the second-hand heat of that flame.

"What the hell did you do to make her this angry?" Meredith asked, but side-eyed Lexie who stuffed another muffin in her mouth.

"Robbins keeps sending me to ortho pages," Alex shrugged.

"Huh, they haven't done that in a while—My god Lexie, how much can you eat?" Meredith interrupted herself, unable to watch her sister throw back muffin after muffin.

"I'm not supposed to say," she mumbled, a few crumbs of muffin flying from her mouth. Her hand rushed up to cover her mouth while her cheeks flushed, but her sister was not deterred. She turned to face the Lexie, forcing her sister to meet her gaze.

"I cannot sit next to the muffin man any longer." Alex said in all seriousness, as Cristina let out light laugh.

"I'm not allowed to tell," her eyes fell to the table, brushing away her previous crumbs.

"Lexie, it's okay. Was it a patient?" Meredith asked in comfort, finally getting somewhere with the girl as she slowly nodded her head.

"Whose service have you been on. Is one of the attendings giving you crap?"

"No, no, nothing like that." Lexie brushed it off, hoping they would let it go, but Cristina cut in.

"She's with Sloan this week. Trouble in paradise already young thing?"

"NO!" She yelled in Mark's defense.

"Then, what's the problem?" Meredith pressured her again.

Looking down at her muffins, Lexie couldn't hold it in anymore. The secret was eating her alive, or she was at least eating everything alive to keep it down.

"Arizona, well...Cristina you know. Wallace died. Our cute, little, loving patient died after Webber forced Arizona into a procedure, and it was on his birthday...Arizona's birthday. She told me not to tell anyone it was her birthday, and I kept it. I had to bite my tongue every time I was even near Mark, but she was so adamant no one could know because she has I guess bad experiences with it...I'm not even sure, but then she was so, so happy for a few days. She was on top of the world happy, and then she crumbled and then Wallace died, and now I can't even get her to look at me or come out with us or..." Lexie rambled so much her face turned a deep red, and Cristina tried breathing for the poor girl herself.

"Wallace died," Alex repeated, remembering Arizona crumble in the morgue as her hand gripped at the boy's shoulder, praying for his bad dreams to go away.

"It was her birthday," Meredith repeated at the same time, wondering why the hospital didn't even get her a collective card like they normally would for a department head.

"Oh, shit has that been why she's been so pissy?" Cristina asked, earning glares from the rest of the table.

"What? I'm just asking. Is that why Callie is pissed too? And what about Mark and Addison they seem fine," Cristina elaborated in surrender to their looks.

"Mark and Addison don't know," Lexie mumbled, glancing back at the remaining muffin in front of her, but Meredith grabbed her hand before she could take the plunge.

"Lexie, you should tell them," Meredith said, still clutching her wrist, but Lexie could only sigh.

Arizona couldn't look at new machinery for peds was rolled in with the check from Wallace's parents. Instead, she stared down at her charts, hoping Webber would just leave her alone today. As always nothing could go her away, and Webber approached her.

"Robbins," he started, but when Arizona's cold, blue eyes pierced into his own, he suddenly was speechless. The surgeon who cried throughout every single one of their interactions faced him now with contempt and an emptiness he knew all too well.

"You know what…I'm going to take a few days off. Is that okay Chief, or do you want to pressure me into staying here one more minute when it is against my suggestion?" When he seemed lost for words, Arizona turned away, brushing past Mark on her way. She stormed home and started to compile a list of hospitals she could transfer to. Along the way, she dozed off, and without her new saying of good dreams here to stay before bed, she woke up screaming to the image of her brother Tim holding Wallace. She started to pant, grabbing at her chest and ignoring the teeth indentations that were left by whichever nurse she fucked in the same closet just to get the image of Callie out her mind. The attempt was unsuccessful much like her attempt now to forget her dream. She wanted to gag when her phone lit up, another call from her parents that would go unanswered. Sweating and sick, Arizona stumbled to her shower, turning the handle all the way over to heat. She climbed in and sat, letting the heat run over her back and the steam fill her lungs as she waited for her phone battery to die, for the calls to cease.

Arizona didn't show up the next day…or the next. Meanwhile, Callie took the time to sort through her feelings. Despite her screaming at the blonde a mere few days ago and despite her countless prayers Arizona would leave and never comeback, Callie couldn't help but search the OR board every day looking for her name.

"You got a big surgery?" Hahn peered around her girlfriend whose face was closely examining each box of the white board.

"Uh, just some hip replacements." Callie mustered out, trying not to jump at the unexpected interaction.

"Well good because I'm taking you out. There's a new sandwich place a few blocks down." Erica smiled at her, the brightest smile she had seen in a while, and Callie honestly hated sandwiches, but something about Erica finally trying had Callie return it.

"Yeah, yeah. Tomorrow maybe we could go to the park too. It's starting to get nice out, and I want to bask in the sun." Callie stammered over the suggestion, afraid of rejection, even from her girlfriend.

"You can take the girl out of Miami, but not the Miami out of the girl," Erica joked, reveling in Callie's light laugh.

It wasn't until Owen Hunt personally texted Arizona about a patient that she mustered up the strength to get out of bed, chocolate wrappers and donut boxes filling the once well-occupied space. She took a long shower, desperately scrubbing the grease from her hair and the crumbs from her skin.

"What do we got," she rushed in next to Hunt who had his hands full in the ER.

"Fire, high school graduation. Room 3 with Sloan," he barked commands, not bothering to waste time with full sentences. Luckily Arizona didn't need the refresher as she slapped on a pair of gloves, running into the requested area.

"Robbins," Sloan looked up in surprise.

"Where do you need me?"

"I'm working on his arms now. I need you to check out his legs, removing any nonviable tissue—I'll graft as I can," he forced out, knowing it wasn't the time to question his friend who had been MIA the past few days. Lexie finally broke, filling in the blanks to a story he tried tying together through pieces from Callie and his girlfriend. Snapping back into surgeon mode, she didn't look this little boy in the eyes. She didn't think about him lying in the same type of bed Wallace had. She didn't think about the boy's parents and older siblings who were probably being treated outside as well. She didn't place essential oil in her mask to distract her nose from the smell of burning flesh. Instead, she sat on a stool, meticulously searching the boy's skin for viable tissue.

As she finished up the legs, she took a minute to stretch her aching back as Sloan started surveying her work and looking for other areas to graft. Without something to focus on fixing, her eyes finally met the ones of the withering boy on the bed who was silently screaming out in terror. His lips trembled, and his body couldn't stay still, agitating the burns even more.

"Jesus," Sloan muttered, as the kid's leg shook once again, almost messing up his work.

"Hey," Arizona peered closer at the boy, moving to sit near his head but still conscious of remaining in his eyeline.

"My brother…" the little boy asked, his voice cracking over the two words.

"I'm sure he's fine. You're all in good hands," Arizona comforted.

"I'll ask someone who his doctor is, okay? We can check on him," she assured again, before sending Grey in search of his family. "Um, what's your favorite thing to do with your brother," Arizona asked, trying to get the boy to focus on talking to her rather than making his hoarse sore from screams as Sloan worked on his skin.

"We would…we would take drives to the gas station and get slushes," he fought to make the words come out of his mouth, and Arizona smiled at his response.

"It sounds like you're both close. My brother would sometimes pretend to drive away and leave me wherever we were." Arizona shared back, willing this boy to stay alert. Mark peered up for a second, eyeing her as she and the patient swapped stories about their brothers. Arizona repressed the memory of his coffin, of the cold flag that sits in her parents' house, of the dozens of missed calls she has on her phone right now from them. Her shoulders and back shook, but she pushed through the thoughts to keep this boy with her, to keep him from the bad dreams that lurked behind them in the dark. She forced the good ones onto him, onto the whole room as she talked about how Tim used to eat whole packets of sugar at restaurants, how he never resisted singing "Man, I Feel Like A Woman" at any karaoke bar they went to, and how once burned ramen noodles so bad by forgetting to put the water in the cup that her father's entire military base shut down for a few hours while they battled the sparks and fumes of the microwave. The boy started to let out little laughs, and Arizona found herself laughing as well, something she didn't even know she could do when talking about Tim anymore. After the third story, she felt the good wash over the room, reveling in the moment of such a sincere connection.

"And you sir, are all done for today," Mark got up, softly clapping for the boy while Meredith finally came back with a positive update on the brother who was also asking non-stop to see his little brother as well.

"Sounds like he has to take you out for another slushie in a few weeks," Arizona winked at the boy, her eyes shimmering a bright blue shade they hadn't in a while. Despite the pain, the boy smiled and was ready for his brother to come in. With that Mark and Arizona exited the room, giving the boys once final glance.

"You did good in there, Robbins," Mark slapped her on the back, keeping his arm around her shoulder.

"I haven't told those stories in god almost a decade," Arizona muttered, wiping a stray tear from her eye.

"What do you say we go find a karaoke place?" Mark suggested, glad to have Arizona back in the hospital.

"You would do that?" she asked, suddenly feeling guilty about ignoring her friends all week without explanation.

"I'm goin' out tonight, I'm feelin' alright. Gonna let it all hang out," Sloan started to sing, twisting around the hallway right into Lexie while Arizona clutched at her stomach to stop the laughter from piercing her ribs.

"Wow," was all Lexie could mutter, but undeterred Mark pulled her in his arms, singing another verse before telling her their karaoke bar plan. Lexie looked over to Arizona for help but seeing the blonde smile a true smile for the first time in a few days, she dismissed it and embraced the moment, even promising to text Meredith and Cristina to come.

"You're a good friend," Arizona stood frozen at how willing Mark was to cheer her up without forcing awkward conversations or drudging up the past.

"Someone had to teach me," he shrugged his shoulders.

"Now let's think of what song we can get Bailey to sing," he added to lighten the moment again.

"Oh, God, she's never going to hang out with us again," Arizona shook her head as Mark approached Bailey, still singing, still dancing, and still her best friend.
