Summary: It's been a month since Jay went undercover, leaving Erin to take care of their two boys while being pregnant. But she's in for a surprise when he shows up just when she needed him the most.

Disclaimer: I do not own anything! Sadly, I wish I did.

So this is my first Chicago PD story. I love Sophia Bush so my path followed me to write one. I hope it's okay. Please let me know what you all think! Thanks!

Girl, I Got To See You Tonight

"Jacob Halstead, please." Erin was begging. She was tired, beyond tired, and cranky. Chasing after two kids while being six months pregnant was not helping at all. "Get off of the couch. The couch is meant for sitting or laying on, not jumping."

"But, Mama, I gotta practice my moon jumping if I'm gonna go to space someday. Daddy says I gotta start now." The little boy, a replica of his father, sighed in annoyance. "I can't do it if you don't let me."

"Well you have years to practice baby, you're only five."

"Well Daddy let's me practice!"

"Daddy's not here right now Jakey boy." Erin frowned at her comment. She hated saying it, admitting it to herself. Jay promised not to take anymore undercover jobs, at least till the kids are older. But that was broken when the request came from her step-in father.

"He's never home." Jacob frowned, similar to his mother's, "I want daddy!"

Before Erin knew what to do, Jacob set off like a switch turning from his normal happy self to a terror. Tears fell from his eyes and his feet stomped on the couch cushion. His rocket ship, that he spent hours decorating and putting together with Voight when she had to do desk duty smashed into the ground, shattering into pieces.

"Dada?"

"Great, look what you wrecked, Jacob. Now you won't have your rocket ship anymore. Grandpa's going to be sad when he finds out." Erin sighed. The normal, sleep through anything little man woke up from the mention of his father. Like Jacob, minus the curly ringlets on the top of his head, Timothy looked like Jay and had his sleep through anything personality. "Go back to sleep, baby boy. Dada's still working."

"No Dada?" His eyes looked sad and before Erin knew what was going on both boys were crying.

"He'll be home soon, I promise. Just another week or two." She might have lied to them but to a four and one-and-a-half years old would not recognize the difference between one week two weeks and possibly longer. Lately she's been forgetting what day of the week it was. "Jacob Hank Halstead, if you don't get off that couch it will be time out for four minutes!"

She glanced up at the clock, gritting her teeth when she noticed it was almost dinnertime. Another dinner talking babble to little kids with no adult interaction. She missed talking to her husband on a nightly bases as they ate dinner and got their sons ready for dinner.

"Sorry." The little boy mumbled plopping down on to the couch. He made his way over to his mother, who stood by Timothy's toys, and placed a kiss on her cheek and hugged her ever-expanding stomach. "Can gampa fixed it?"

"I'm not sure, Jacob. If you didn't throw it, this wouldn't have happened. You may have to ask him next time we see him. Now till then keep Timothy distracted while I'll clean up this mess."

"I help?"

"No, you may get hurt." Erin waddled her way to their pantry and tried to quickly clean up the mess the young boy made. "No more throwing toys, baby."

"I sorry, Mama. Daddy would've caughted it."

"Caught, not caughted." Erin chuckled at his childish speech. "I don't think he would have JayJay. Maybe if you didn't get angry and throw it."

"Gampa says no angwy unless bad guys."

Another chuckle game from Erin's list as she could picture her step-in father saying that to her young son. Everyone at the station loved the boys, they're were the up and coming new generations of detectives to take over for Voight- his idea. Erin would bring them up with her when she would be on desk duty, like now, to keep her father occupied without asking too many questions.

Like a cue, Voight walked in through the door holding two new toys for his grandsons.

"Gampa!"

"Ampy!"

Both boy's screamed when they saw their favorite person. At times Erin thought her sons did love her father more than they loved her but then they'd give her hugs and 'tisses' as Timothy called them and that thought went away.

"My favorite little men." Voight never showed emotion before, until his grandsons came into the world. Besides Erin and Jay, Voight was the next person to hold both her sons. He was the one pacing up and down the hallway of the hospital when Erin was in labor. "And Erin."

"I feel the love." Erin's sarcasm made Voight laugh.

"You know I do."

"Yeah, yeah."

"Presents?" Jacob questioned being listed into Voight's arms.

"So like your father, Jacob." Voight smiled roughing up the boy's brown locks. "Of course I brought presents. Someone needs to spoil you two. I got my favorite astronut the most amazing gift."

He passed the bag off to Jacob who tore it apart in a second. Inside was a child sized space suit that made Jacob's face light up like a Christmas tree.

"Mama look! I gonna be an asstronut."

"It's astronaut baby. You'll be the best one there." Erin sat back and watched the man that saved her from everything interact with two little men that she would save from anything. "What do you say, Jayjay?"

"Fank yous Gampa!" Jacob jumped out of his grandfather's arms and sprinted off down the hallway to his room.

"That boy." Voight laughed. "How's my favorite Timmy?"

"Timothy, not Timmy." Erin was adamant that she did not want to nickname her son Timmy. She despised Timmy. Tim, Erin approved of, but Timothy is the name she fell for. "Please."

"Lighten up, Er. You need to relax."

"When your husband is gone for a month with no word from him because her so called father sent him away and you have two young energizer bunny sons there is no such thing as relaxing."

"That's why it's grandpa to the rescue. These munchkins are mine for the night. You go relax and enjoy yourself."

"Really?"

"Justin's bringing his kids over. They'll be occupied." He shrugged it off. His son was an iffy topic that even Erin didn't bring up much. Justin and Voight's relationship was a struggle but since the introduction of kids into the family, the father and son got along better, but not the best.

"Justin still not home?" She was sad to find out that two-kids in a two-year marriage had ended in separation. She did warn him not to marry his wife because she was pregnant and wanted her to be able to have his military benefits.

"The couch is his home, just like old times." Voight did his half-smile. "Now let me get these rugrats out of your hair. You relax so he doesn't come too soon."

"It could be a she for all you know."

"In this family, it's all men." He stated an accurate fact. Justin had two sons and so did Erin. It was most likely that this one will be a boy too. Erin just couldn't find out without Jay being there and she hasn't been to a ultra-sound since before Jay left.

"Enjoy them, and no sugar, got it? I'll pick them up in the morning." Erin hugged her youngest son tightly and kissed him goodbye.

"Bye-bye Mama." He waved. "Tisses?"

"One more tiss." She shook her head realizing she has been picking up on her son's language. "Now behave."

"Bye bye Mamma. Gampa says we can have pizza and soda with Uncle Justin." Jacob loved his uncle tremendously. Whenever Jay got sent off for work, Justin would step-in without even being asked too.

"No soda, Dad!" Erin called after them as they walked out of the apartment door.

When baby number one came along Erin desperately tried to convince Jay to move to the suburbs. She wanted what she never got a chance to have. She wanted that whole white picked fence and big enough yard to have a puppy and kids running around. Jay dismissed that with the compromise of finding an apartment with an elevator to making going up and down with a young son easier while staying closer to their job.

-XO-CPD-XO-

Erin spent the past hour cleaning the apartment up and organizing the boys' toys enough that the more annoying ones were packed in the top of the closet for days were its too cold out to do anything in the winter and Jay will be stuck home with them. She also ordered Chinese food and took a long relaxing tub.

"Food is coming, you can stop kicking me little one." Erin rubbed her hand over her newest baby's kicks. "That's my bladder you're are kicking."

"Like the baby can understand you."

In the distraction of the kicks, Erin didn't notice who joined her in the apartment. There, in the doorway stood her husband of five years. It took a minute for it to click in Erin's mind that Jay was standing there; her noise and stomach took notice in the bag of Chinese food he was holding.

"You're, you're here." Erin was in complete shock still. Tears came falling from her eyes.

"Hey now, no crying." Jay protectively wrapped his arms around his wife, kissing her head softly.

"You weren't supposed to be home yet."

"Voight had a little help with that."

"He knew?"

"Why do you think he took the boys? You my dear need a relaxing night." Jay kissed her lips. "Plus I can think of some other things we can do tonight. No boys till I have to report to the station tomorrow afternoon."

"Why'd you come home so early?"

"You complaining that I'm home beautiful?"

"No, no, not at all." Erin still had tears falling. "I'm an emotional mess."

"I just had to see you. I've missed you."

"I missed you too Jay. But, your still an ass for leaving me for a month." With that Erin stood up and stomped her way to the shared bedroom. Her emotions were running wild and he had to laugh when he saw her stomping back. "Baby wants Chinese food."

"What baby wants, baby gets."
