Disclaimer: I don't own. If I did, I'd be rich. The only characters I own are those with names that I've clearly made up…

Okay, so instead of setting the relationships via relatives here in the story, which I could do, I'm going to do it like this. The other way would be too hard.

Teresa is Alex's sister's daughter and Bobby's brother's daughter. Alex and Bobby pretty much raised Teresa, from the time she was little. Alex and Bobby will eventually become an Item. Lucas is Olivia's brother's son, and Elliot's sister's son. Olivia and Elliot are somewhat of an item, but only behind closed doors.

"I don't really want to go out with him" Teresa argued relentlessly with her aunt, trying out different outfits.

"He's a really nice guy; even your uncle Bobby thinks so. Besides, he's the nephew of a couple of good cops in SVU."

"Great, the rape squad." Teresa rolled her eyes; she hated blind dates and couldn't, for the life of her, figure out why her aunt and uncle were always trying to fix her up with 'suitable young men?' Why couldn't they themselves just hook up; they'd been partners for years, trusted each other immensely, cared a great deal about one another—it was written in the stars. But no, her aunt still mourned the death of her uncle Joe; no matter how many times the family told her to move on. And her uncle was….different, to put it nicely. At best, couldn't they just ignore her entirely, like her parents did? Nope; still, she couldn't be that lucky—to them, that would be like ignoring their child.

"Teresa he is a very lovely young man. You'll have a good time, I promise" Alex looked her flat in the eyes; 'eyes meant no lies,' according to her aunt.

"Fine, but if I don't like him after an hour into it, which I probably wont, I'll be calling for back up"

"My cells always on for you" Alex had a genuine smile plastered on her face.

"Yeah, it better be" Teresa grumbled before going in the bathroom to fix her hair.

"Tweety has it SO easy around here" She mumbled childishly to herself.

"So what should I say to her?" Lucas was putting up a multitude of ties to his shirt, trying to figure out which one accented his outfit of choice best. Elliot picked out the best fit and handed it to his nephew, setting the others back on the hanger.

"Just be yourself; chicks dig an honest man" Elliot helped Lucas adjust his tie appropriately, and then smiled at him in the mirror. "Awesome."

"Since when did you start saying things like chicks and dig in the same sentence?" Lucas turned to face his uncle, raising his eyebrows in a suspicious manner. "Aunt Liv is totally a bad influence on you."

"Your aunt is… well, she's different" Elliot said; but that's all he would say on the subject.

"I'm sorta glad you guys hooked up. I mean I guess I always knew you would, but for a while there deep down I had my doubts. Don't get me wrong, Aunt Kathy was great but things were shaky for so long"

"When did you get to be such an expert?"

"I'm 19, Uncle El, not 12. I've learned to be a little more observant."

"Well knock it off, it's not healthy" Elliot wasn't sure he liked the new and improved Lucas; the 'observant' one, who gave out relationship advice. Then again, if something was new, it certainly wasn't improved, there'd never been another like it, so Elliot figured the boy had always been this intelligent and observant and he had somehow just missed it.

Dinner between the young adults was quiet and awkward. Teresa had settled on a light green dress which accentuated her curves and legs perfectly. They ate at a cute little Italian diner, about 10 minutes from the precinct. Elliot had suggested it, and the weather was perfect for a little outdoor dining with some soothing music.

After dinner, Lucas invited Teresa to his place for a little dessert and a cup of coffee; normally she would have declined, but the long walk back to her place was more than she could bear without sugar and caffeine. Hesitantly, she gave in, and they headed back to his place.

"So this is it" He said, opening the door to the tiny studio apartment.

"Cozy" Teresa said, almost sarcastically. She was used to dating guys with… well, much bigger places. Lucas was different, though, she could tell that from the start.

He handed her a plate with an Italian dessert on it, following the theme of the night's dinner, and then a small glass of champagne. He had to be careful how much he gave her; they were both still under aged and came from a long line of cops on each side of their families.

"Thank you" Teresa drank up, grateful for the liquor to hide her uncomfortable stance.

"You're welcome. So tell me about yourself…" Lucas began…and as the night dragged on, they got to know a little more about each other than either one had bargained for.

3 months pass

"Look, I don't know what we're going to do, but we have to do something." Three months had passed since Teresa and Lucas had their first date; since then they'd been more like casual friends, secretly pining for each other. But Lucas was pompous and could be quite arrogant at times- the kind of man Teresa said she'd never date. And Teresa… well, she could be a little too nice at times-the good girl Lucas could never picture himself with.

"Alright, well are you sure about it?"

"It's been three months since we… ya know, hooked up, I haven't gotten a period, I've been feeling sick yesterday, I peed on a stick, and oh yeah, the doctor confirmed it. Yes, I'm sure" Teresa irritably turned the other way; how could it have been possible for her not to be sure she was pregnant? Or any woman, for that matter?

"Well then what do you want to do?" The choice was, of course, Teresa's. She was the mother and whatever she decided, Lucas was stuck with. The baby had to have been his; Teresa wasn't usually the kind to have sex with no strings attached; he could tell that just in the way their bodies moved together when they made love.

"It's our fault and out mistake. I want to keep the baby… of course; I also want to finish up college. I don't know, I'm so confused."

"Whatever you decide to do is fine with me" Lucas tried to comfort her; there wasn't much else she needed his help on-in fact, he'd helped enough.

Teresa let out a deep breath. "Alright, then I want to keep it. After all, this baby is as much a part of the people I love as it is me. And the same goes for you." The decision was an even easier one to make than she thought it would be, but still, she couldn't help but nervously rub her stomach.

"Why are we here?" Elliot walked in, afraid something serious had happened. "Lucas said it was urgent."

"Don't worry, everyone is fine, but it is urgent" Lucas took his spot at the dinner table beside Teresa. They'd called their closest relatives over for dinner that night so they could break the news to the family; after all, if they were going to do this, be parents, they were going to need support from the ones they loved the most.

"Teresa will be please tell me what is going on before I have a heart attack?" Her uncle Bobby looked flushed under the eyes.

"Just wait till everyone gets settled in and then we can all talk." Teresa looked at her uncle and then to the rest of the people standing in her living room. Tonight wasn't going to be a fun night, she knew that for sure.

Lucas had ordered in Chinese in order to break the news; he'd been too tired to cook a home cooked meal, and plus, what detective DOESN"T eat Chinese food?" He looked around the table but found no answers.

"Lucas, Teresa, enough of this already! Will you please tell us what is going on so we can get it over with?!"

Teresa sighed, inhaling deeply and resting her left hand on her stomach. "I'm pregnant" She told them, then sat down for a normal family dinner.
