A/N: This is something that popped into my head after reading "Temptess." This is not meant to be a copied story or anything, just a little something that my crazy brain came up with, hope you like it!
"He left me!" Olivia yelled, running into the precinct.
"Liv, what's wrong?" Fin asked.
"Elliot, he left me!" Olivia repeated.
"What why?!" Munch asked.
"Kathy is having another kid, she found out before he started dating me, and didn't tell him. He went to pick up the kids, even though she told him not to, but she was late, so he did, and he found out, and he left me!" Olivia yelled.
She ran into Cragen's office.
"Liv, what's the matter?" Cragen asked, standing from behind his desk.
"I wanna transfer, I don't care where, just somewhere, and fast, please!" Olivia blurted out.
"Why?" Cragen asked.
"Because Elliot left me, and I can't work with him after that." Olivia said, trying to hold back her tears.
"Last time you asked for a transfer, IAB said no, so it's a waste of time to even ask, they think you two work too good together, I'm sorry." Cragen said sympathetically.
"It's ok, it's not your fault." Olivia said. She walked out and saw Elliot sitting at his desk. She couldn't hold it in any longer. A sob ripped past her lips, and her hand flew to her mouth to cover it up, but Elliot had already turned to her.
"Liv?" he asked. Olivia sprinted for the cribs, and Elliot ran after her. She had already locked the door. Elliot knocked on the door.
"Liv, open the door." he said.
"No, go away Elliot, I hate you!" she cried.
"No you don't Liv, you're just upset." he replied.
"Oh really, I hadn't noticed." she said sarcastically.
"You need to talk to me." Elliot said softly.
"Ok fine, let's talk about how you left me for your ex wife, that'll surely make me feel a lot better!" Olivia yelled.
"Liv, come on, she's pregnant." he said, getting slightly annoyed. She unlocked and opened the door. Her mascara was running down her face.
"So am I you idiot, so am I." she shoved the ultrasound at him, and ran downstairs. Elliot just stood there shocked. Finally, after a few minutes, he followed her.
"Liv, is it true?" he asked stupidly.
"I wouldn't have an ultrasound if it wasn't you idiot." she replied, gathering her things.
"Liv, please don't leave." he said.
Olivia scoffed.
"Wow, that was stupid, you wanna pull that after YOU left ME?" Olivia asked in disbelief. She grabbed her purse and coat, and walked towards the elevator. Elliot ran after her. He caught the door before it closed.
"Liv, wait!" he insisted.
"Elliot, go home to your WIFE, I'll raise this baby on my own, while you and Kathy continue with your happy little life. I've been on my own my whole life, and I'll be on my own now, and you don't even have to fight for joint custody, I'll give it to you. Just go." she said, pushing him into the hallway. She pushed the ground floor button, and was gone.
