AN: Thanks to those of you who continue to offer feedback and support!

I also wanted to offer a TRIGGER WARNING for anyone who is sensitive to death of a loved one. There's also a bit of swearing in this chapter.

Callie couldn't breathe. Every thirty seconds or so, she had to remind herself to puff air out and suck it back in. She was supposed to land in Pittsburgh five and a half hours ago. However, due to rain delays, an incompetent flight attendant, and a faulty technological system, she was only now bent over trying to catch her breath after sprinting to baggage claim. Thankfully seeing her red suitcase drop onto the conveyer belt, she snatched the bag up and headed toward the doors, intent on hailing the first cab she saw and paying the driver triple to get her to her best friend's home as fast as possible.

Once settled in the cab and merging onto the highway, Callie realized how unprepared she actually felt. She wanted to get to Arizona as fast as she possibly could, but she had no idea what she would say to her when she did arrive. Did she even say anything? Rubbing a hand over her distressed face, she quickly checked her phone, finding texts from her parents, Aria, and Tim, three missed calls from Mark, and a voice mail from Teddy. Answering everyone back to let them know she had landed and was on her way to Arizona's home, she began compose a final message to the blonde herself. Fingers stilling over the keys, she tried to force herself to come up with something, but with a shaky gulp, realized she was at an absolute loss. Shaking her head and deleting the draft, she scrolled through her contacts until she found Barbara and Daniel Robbins' house number. Putting her iPhone to her ear, she waited rather impatiently for someone on the other line to pick up. After three rings and a few seconds, which felt more like hours, the woman she viewed as a second mom for the majority of her life said 'hello'. "I really need you and Daniel to get on a plane to Pittsburgh. Forget the grudge you've been holding with your daughter. I don't care what you have to do to make it happen, but she needs you. Please just get on a plane. Please."

Still panicking twenty-five minutes later, Callie hesitated for just a moment before ripping the front door open and making her way into her best friend's home. Noticing the Halloween decorations adorning the front hall, she tried to smile but a sense of dread filled her stomach. Halloween was one of Arizona's favorite holidays. Callie was sure future Halloweens would be filled with anyone but excitement. Rather than butterflies, she felt as if chomping, aggressive dinosaurs were battling it out in her stomach. She was trying her hardest to determine what to do next when the pitter-patter of tiny feet brought her back to reality.

"Aunt Cal." The tiny, scared, trembling voice shook Callie to the core. She'd never seen her niece like this and the now four-year-old looked like she would become invisible and poof away in a split second if Callie didn't get to her.

Quickly scooping Ellie up, Callie squeezed her as tight as possible without harming the little girl. "Baby elephant. Baby, where's Mumma?"

Instead of answering, Ellie clung. Tiny fingernails dug into Callie's neck, but the brunette couldn't find it in her to pull her away. "Aunt Cal," came the whispered plea, causing Callie to pull her impossibly closer.

"Oh, sweet girl. I'm so sorry. Baby, you have to tell me where Mumma is," she pleaded, watching Ellie draw a few centimeters of distance and nod toward the back of the house. Leaning in again, the four-year-old wrapped her arms around her aunt's neck and squeezed.

As Callie slowly made her way toward the area Ellie had hinted at, she drew all her strength to make sure she wouldn't burst into tears. Finally finding Mark and Teddy in the kitchen with a sleeping Kylie in Mark's arms, Callie felt the dam bubble over. As quickly as she could, she swapped Ellie into Teddy's lap, despite screaming protest, and wiped at her face, hiding all remnants of salty tears. "Where is she?" she pleaded, this time with the adults in the room.

"Out back," Teddy whispered, trying her best to calm Ellie.

Placing a long kiss onto her niece's head, Callie gently shushed her. "Elephant, stay with Aunt Teddy and Uncle Mark. I need to go see Mumma, okay? I promise I'm not leaving. I'll be back." When Ellie calmed down and nodded slowly, Callie allowed herself to open the sliding glass door to the deck. Spotting a blonde head sitting on the family tree swing at the far end of the yard, she opened the deck gate, made her way down the steps, and was standing next to Arizona before she recognized her muscles moving.

Her best friend was staring ahead with a blank look on her face. "Arizona," Callie croaked, not knowing a better way to get the woman's attention without frightening her out of her bubble.

At the sound of Callie's voice, Arizona's shoulders slumped and her body crumpled in on itself. "Calliope," she cried, already reaching out to grasp onto her best friend.

Hugging her hard, the brunette ran her gloved hands up and down Arizona's freezing bare arms. Pulling her jacket off one-handed while keeping a hold of Arizona with her other, Callie quickly wrapped the fleece around her best friend before pulling her back into an embrace. "I am so sorry, Arizona. I'm so sorry, sweetheart."

Ten minutes later and Callie began feeling the chill, wondering how Arizona lasted god only knows how long outside without a jacket. Pulling her up, she began walking them toward the house, moving around toward the front door to avoid Ellie or Kylie seeing their mom falling apart. Once inside, Callie practically dragged Arizona up the stairs and into the guest room, predicting that the master bedroom may seem impossible at the moment. Sliding up against the headboard, she motioned for Arizona to join her.

Teary eyed and looking entirely lost, the blonde fell against Callie's side, allowing her best friend's arm to wrap around her back and pull her flush against her side.

"Calliope, what am I supposed to do?" she asked desperately, grasping for any kind of answer.

For once, the brunette was at a loss for how to make Arizona feel better. The only thing she could think of that would lift Arizona's spirits was impossible. She couldn't bring back the dead. Instead of continuing to rack her brain for the right thing to say or do, Callie closed her eyes and tried to convey as much comfort as she could through a hug. "You're supposed to do whatever you feel like doing. This sucks, Arizona. I can't sit here and lie to you and pretend like everything is going to be okay because it's not. You've just experienced a tragedy and the more it sinks in, the worse it's going to feel. I don't know what you're supposed to do, Zo. All I know is that whatever that is, I'll be here to help, okay? I'll help with the girls, I won't leave your side, anything. Jesus, I'm so sorry, Arizona."

"Why do shitty things happen to good people? She didn't have an evil bone in her body." Sitting up, Arizona's face changed from heartbreak to anger to confusion to a multitude of other emotions in a millisecond. "Why did this happen? We didn't do anything."

Eyes welling up, Callie frantically shook her head. "I don't know why this happened, sweetheart." Gripping her best friend's hands, Callie felt a tear run down her left cheek. "I don't know. It's not fair, you're right." As another sob wracked the blonde's body, Callie shook, too. "Zo, what can I do? Please tell me what I can do?"

"I miscarried the night Katelyn died," Arizona wept, unable to hold the secret in anymore. The only people who knew were the doctors and nurses and hospital personnel that helped her at the hospital, and now Callie. "I'm sorry!" she cried, almost hitting herself for how the news came out. "I just…I can't…I don't…how could this happen?"

Callie, feeling like a fish out of water, tears running down her face at the news, pulled Arizona against her again. She thought loving Arizona and having to witness her marry, have babies, and love life without her was the hardest thing she'd ever have to watch. She was wrong.

"How is she?" Mark whispered a few hours later when Callie made her way downstairs to try and find out more details about what had happened.

"Fell asleep about thirty minutes ago. She's…I've never seen her this broken. I don't know what to do. Helpless. I feel helpless."

Walking over and beginning to rub Callie's shoulders, Mark nodded. "We all feel helpless, Torres. Arizona's falling apart at the seams and who could blame her? Ellie has no idea what's happening, but is old enough to understand that Mommy isn't here and Mumma can't function. Kylie is on a scream, sleep, refuse to eat, scream some more schedule." Sitting down next to the brunette, Mark dropped a defeated head into his hands. "Forty-eight hours ago I was teasing Katelyn about her failure of a pumpkin. All she did was cut out a stupid hole in the middle of the pumpkin and glue glitter around the edges. I keep looking at the door expecting her to waltz on through with a new fucking pumpkin and carve it into a Michelangelo."

Callie genuinely smiled. "Sounds like Kayt."

Teddy, placing a cup of tea in front of Callie, joined the two at the table. "This doesn't seem real," she murmured, folding the watery tissue in her hands.

Sighing, Callie decided it was now or never. "All I got out of Arizona when she called me last night was that there had been a horrible accident, Katelyn was dead, and something about there being a redeye to Pittsburgh. After briefly talking to Tim, he told me Arizona saw it, saw the car hit her. We didn't talk long because I had to board the plane. What else don't I know? I need to know what happened."

Mark nodded and ran a hand through his disheveled hair. "They were setting up for a fundraiser for the line and the kids. Katelyn had insisted on running streamers throughout all the chairs on each side of the sidewalk. Teddy and I were doing one side and Arizona and Katelyn had taken the other." Stopping, he coughed into his hand in an attempt to remain composed. "Next thing I know we hear screeching tires and Arizona's shriek. The car drove away before any of us could get a good look at it. We were…we…"

Teddy, noticing Mark's demeanor quickly changing, picked up where he left off. "We were farther down the street becau-"

"Katelyn had this stupid idea that if they started at the other end, the colors would end up matching better. We could have just taken turns with the damn blues. She only got the fucking blues because of me. She wanted red. And I-I threw a fit in the store, knowing I would get my way and she would get the packet of blue. She-god-she wanted everything to be perfect because there were big shot investors coming and I wanted so desperately to sign some sort of deal with them. That way, I could take the time off and have, have the baby. The idea of becoming primarily a stay-at-home mom was so fucking appealing to me. And Katelyn was always so god damn flexible, she didn't even bat an eyelash when I brought it up. All she did was try and make the entire event perfect so my new dream could come true." Arizona, who had heard the tail end of the conversation stopped to take a breath. "She was in the street because I had dropped the fucking blue streamers and they rolled off the sidewalk."

Falling into a seat, one hand clutched at her heart, which Callie thought was a frantic attempt at making the pain alleviate somewhat. "All over the stupid, stupid, stupid blue streamers." Bringing a hand to her mouth, she stifled a sob. "Katelyn's dead and I lost our baby and I'm falling apart," she whispered, strained, looking around at her group of friends for some sort of sign that all of this was one big nightmare.

After a tense few seconds, Callie's hand shot out to grip Arizona's. And the doorbell rang.

I knew some of you would guess this, but I hope it was still somewhat of a surprise. Of course, they aren't going to fall into bed with one another immediately because that's unrealistic and not how I see either dealing with this, but we'll get there.
