Glass smashed out of both vehicles.

Olivia had covered Kathy with her body, trying to protect her for the other car.

They spun around for several seconds before the car hit a fire hydrant. It burst, causing water to gush sky high.

"KATHY!" Olivia's eyes were blurry and her head was throbbing, but she had to see if her best friend's wife needed help.

"What?" Kathy's head was bleeding and was in a daze.

Olivia grabbed her phone and called 9-1-1.

"9-1-1- what's your emergency?"

"This is detective Benson, 4-0-1-5. Our cab was hit head on. One of the passengers is seven month's pregnant. We need an ambulance now!"

They rushed an ambulance to the scene of the crash. The fire department was also on the way once they got a call about the busted hydrant.

When the paramedics arrived, they were surprised to see two pregnant women. Olivia was so set on getting Kathy help, she had forgotten about herself.

"You're bleeding ma'am." The paramedic tried to take Olivia in as she looked to be in worse condition, but she insisted Kathy go first.

Reluctantly, they loaded Kathy into the back and drove off, hoping a second ambulance would get there in time.

Elliot had planned on picking up his wife when he was off work. He called her to find out where she was and he got no answer. When he tried Olivia, he also got no response.

That's not like her. She always picks up her phone.

Concerned that something had happened to her, Elliot called Casey.

"Have you heard from Olivia?"

"She and Kathy went to get massages."

"I know, but neither of them are answering their phone and they should have been done with that almost an hour ago."

Casey frowned. "I'll call Olivia and see." Again, Olivia didn't pick up the phone.

Casey called Alex. "Have you heard from Liv?"

"No, is something wrong?"

"Elliot can't get ahold of her or Kathy, and she didn't answer when I called her."

Alex knew her phone wasn't dead. "I charged it for her last night." Alex remembered that she had installed Find My Phone on Olivia's phone.

"Let me look up her address."

Alex pinged the phone and found out "she's in the East Village."

Alex rattled off the address and Casey said she'd text Elliot.

Once Kathy was gone, Olivia started to realize she was hurting. "Shit!"

A passerby saw her and offered to drive her to the hospital. "Do you need any help Miss?"

He flashed a badge, telling Olivia that he was a fellow cop. "I need to get to a hospital. Our cab got t-boned."

He grabbed some towels from the back so she could hold them to her side.

"This is Detective Amaro, badge number 5-1-3-8. I have a passenger who's pregnant and wounded. We're on our way to Mercy. I'm not slowing down!"

He put on his sirens and started blazing through the intersections.

When Elliot got to the scene, all he saw was carnage. Both cars had been destroyed and the scene had been cordoned off.

Why would Olivia and Kathy be here? When he looked at the smashed cab, he realized they must have been inside.

Elliot flashed his badge and made it past the police tape. "What happened here?"

The rookie looked at him. "A drunk driver came and smashed into the cab. Both drivers were killed."

"And the passengers?"

"There was a pregnant passenger. She was taken by ambulance to Mercy and …" He didn't need to finish he sentence.

Elliot was on his way. He had just gotten back in his car when Casey called him back

"Stabler!"

"Did you find them?"

"They got hit by a drunk driver. I'm on my way to the hospital and I don't know their condition."

Casey almost dropped the phone. I have to get Alex.

The blonde immediately blamed herself. "I should have driven them. I should have …"

Casey cut her off. "Alex, if you had driven them, you could have gotten killed. You did nothing wrong Honey."

Alex heard Casey's words, but she was in a panic. If anything happened to their brunette, she'd never forgive herself. "Let's get to the hospital."

Casey drove. She didn't trust Alex driving right now.

"Where's my wife!" Elliot came barreling through the hospital doors like a bull in a China shop.

The receptionist frantically checked her computer. "They're prepping her for a caesarian section."

She wasn't due for another month in a half.

"They couldn't stop the delivery?"

She shook her head before giving him the room number.

He raced down the hallway, past the other patients and nurses. One of them chastised him. "Slow down!"

He ignored her.

When he got to the room, the nurse was just putting in the sedative.

"How is she?"

Kathy could barely see him. Her eyes were still blurry. "Elliot?"

"Under the circumstances, your wife is doing well, but we have to do the surgery. Your son needs to come out."

He kissed her head before they wheeled her into the surgery room.

What do I tell the kids?

When he called Kathleen, she asked him, "What happened to Olivia?"

Elliot had no idea. She must have been okay if she didn't get in the ambulance, but why wasn't she here or at the scene? It wasn't like her to just disappear like this.

"I don't know."

He didn't know until he heard her yell, "son of a bitch!"

"Liv?"

He followed her voice and was surprised to see a young detective outside of the door.

"Who are you?"

"I'm Detective Amaro. I found Olivia and drove her to the hospital."

Elliot frowned in confusion. "Why didn't she take an ambulance?"

"I'm not sure, but she looked confused, and she was bleeding."

Maybe she wandered away from the crash looking for help.

Casey hadn't even put the car in park before Alex hopped out the car and ran inside.

"Alex, wait up!" Casey threw on the break, and ran inside, barely remembering to lock the car behind her.

Casey finally caught the blonde at the reception's desk.

"We're looking for Olivia Benson."

"And you are what to her?"

"We're her partners."

The receptionist raised an eyebrow before she looked on the computer. "I'll need your IDs," she said icily.

Alex looked ready to throttle the woman.

Casey kept her hand on Alex's back. Forget about her; she's not important.

Olivia had listed both of them as their emergency contacts.

"She's in room …"

As soon as Alex heard the number, she took off.

Casey regretted that she didn't go running more. "Alex! Slow down!" Seriously, how does she run in heels?

The blonde almost ran into Nick when she got to Olivia's room.

"Who are you?" she demanded.

"I uh …" he started to stammer; the woman scared him.

Casey came finally huffing and puffing.

"Who is this?"

"I don't know. If you're the asshole that hit Olivia's cab!"

"Oh no. I drove her to the hospital."

"Why didn't she take an ambulance?"

"I don't know," he told her.

Just then the doctor came out.

"How is she?"

Seeing Alex's urgency, the doctor skipped his introduction and got straight to the point. "We were able to stop the pre-term labor, but the mild sedative we gave her made her rather woozy. She'll need to stay here overnight."

"She'll be okay?"

"She'll be fine, and her baby looks good too, but I want her on bed rest for the next two weeks, and she should take off of work for a least a month."

Alex went in to see her.

"Thank you for getting her here," Casey said to Nick, who was still scared of the blonde.

"I was just doing my job."

The surgery was a success. When Kathy woke up, her husband was holding their newborn son in his arms.

"The kids are on their way," he told her before he handed her their son.

He was perfect. A little small, but he had a healthy hue. "Is Olivia …"

"She's here." He wasn't sure on her condition.

"They tried to take her."

Elliot frowned. Was this a targeted attack? "Who tried to take her?"

"The ambulance," she said weakly. "She was worse off than I was, but she made them take me first."

It didn't even occur to Olivia that she might have been hurt. She was always unbreakable. That's why Nick had to drive her.

Kathy stayed with Eli as his father went to find out what happened to Olivia.

By the time he got to her room, the brunette was already asleep.

"How's Kathy?" Casey questioned.

"She's great, and our son is perfect. How is Liv?"

"She'll be fine," Casey told him, "once she gets her rest."

"Bring him by tomorrow. I'm sure Liv will love to meet him."

When the brunette woke up, she saw Alex sleeping in the chair next to her.

"What are you doing here?"

"I wasn't going to just leave you here."

Olivia sat up. "You should have been at home in a real bed; where's Casey?"

"She had to go. There was a lead on the Soho Rapist," as the media had dubbed him. She had to get a search warrant for Munch and Fin.

Olivia had forgotten all about the case. "What did they find out?"

Alex shook her head. "Nope. You are not working. You will not be thinking about working."

"Alex …" Olivia whined. "I'm fine."

"You are NOT!" Alex snapped. "You could have died. Refusing an ambulance when you were bleeding severely. Are you out of your mind?" When Elliot told them of the stunt Olivia had pulled, Alex was ready to wake up the detective just to throttle her.

"I didn't think I was that bad. The adrenaline, I couldn't feel anything."

"Next time, trust the paramedic who tells you that you need to be hospitalized."

Of course, Olivia made no such promise. "Is Kathy okay?"

"She and Eli are fine."

"He was born?"

"Yes, thanks to your heroics, as ridiculous as they were, they are both just fine," Alex's face softened, slightly. "You really saved the day, and that's why … I didn't murder you in your sleep for giving me such a fright."

"Oh you're so sweet," Olivia said dryly.

Alex kissed the corner of her mouth. "I am … and you're off the clock for the next month."

Olivia's face fell. "Hell no!"

Alex laughed. "Doctor's orders. You are not to get yourself into any trouble, and I will know you're safe."

"You paid the doctor to do this … didn't you?" Olivia was only half serious; Alex had the money to do this.

"You'll never know."

It was hard to stay mad for long. Alex did smuggle her a chocolate donut into the hospital.

"Ooh!" Olivia gasped when she got to the middle. "There's hazelnut cream in here!"

"I thought you'd appreciate that."

Later that day, Elliot brought his son to meet Olivia.

"He's so cute," Olivia said.

Elliot grinned. "I know."

"Good thing he looks nothing like you, huh!"

He rolled his eyes. "You're such a charmer, Liv."

"I know I am. Have the kids been here to see him?"

"Dickie and Lizzie were here last night. Kathleen will be here this afternoon."

"I'm sure they're excited."

Suddenly, the moment became more serious. "I can't thank you enough for what you did."

"Elliot, it wasn't that big of a deal."

"Liv you almost died, so that my wife and son would be safe. I can't thank you enough."

"We're partners Elliot. I have your back, and you have mine." They've been through too much shit together, to get all sappy now.

Olivia was ready to kiss the ground when she was able to leave the hospital. She did not like, however, being in a wheelchair.

"Doctor's orders," Alex told her as the pushed the brunette.

"This doctor needs to get off my back!"

Alex and Casey helped her get into the back seat and it was time to get them home.

"Can we stop and get food on the way?" The redhead pleaded. She had forgotten to eat breakfast and only had a power bar for lunch.

"The baby wants pizza," Olivia declared.

Alex knew better to argue with hungry lovers. "Pizza it is."
