A/N: Some of you have been asking about Casey. This chapter will answer some of your questions, but I promise he'll make an appearance later on in the story! Also, I know some of these chapters have been a little short; there are longer chapters coming!

"Hey, how are you feeling?" Kelly asked as Gabby shuffled out of her room on Wednesday morning, still half asleep.

"I've only thrown up once this morning, so it's progress," she answered, plopping down on the couch next to him and grabbing the box of crackers that had become a permanent fixture on the coffee table since she'd arrived. She ate a few before adding, "At least one benefit of not being able to keep anything down is that I've not gained any weight." It was true. There was definitely no sign of a baby bump yet; her all-day sickness had made sure of that.

"Are you nervous about today?" Kelly questioned.

"A little," Gabby admitted. She sighed. "I've wanted to be a mom for so long, Kelly. I thought it was going to happen when Matt and I got pregnant, but the I lost the baby. Then losing Louie and finding out about the aneurysm…I'd given up on that dream. Now, that dream is the most real it's ever been, but it could all be over after today, depending on what the doctor says today."

She and Kelly had discussed her pregnancy at length over the last few days. They'd both agreed that whatever the doctor recommended was probably the best course of action, but they also admitted that they both really wanted the baby. As unexpected as it may have been, it was something they were both happy about once the initial shock had worn off. Kelly had promised to support her in whatever decision she made, which, after how things had ended between her and Matt, was exactly what she needed to hear.

"No matter what the doctor says today, you can stay here as long as you want," Kelly told her.

"Kelly," Gabby protested. This had been a constant topic of conversation since she'd arrived, and they'd yet to come to an agreement. "I can't keep imposing on you. If I'm going to be in Chicago for a while, it only makes sense for me to find my own place. You need your room back."

Kelly shook his head. "You're stubborn," he muttered, giving up for now.

"This is going to be a bit cold, Ms. Dawson," the doctor warned as she squirted ultrasound gel onto Gabby's stomach.

As the doctor moved the wand around, Gabby felt herself growing more nervous. She'd been trying to put on a brave front and hide just how scared she was, but it was getting more difficult now. She felt Kelly's hand slip into hers and give it a squeeze, and she looked up at him gratefully.

"Would you like to see your baby?" the doctor asked.

Gabby looked up at Kelly, unsure of how to answer. As much as she wanted to see her baby, if the doctor gave her the news she was dreading, she wasn't sure she'd be able to handle if after seeing the baby.

"Can we get printouts for later?" Kelly asked. "I'm not sure we're ready to see it just yet."

The doctor nodded in understanding. "Yes, we'll print a few copies out for you." She put the wand away and began wiping off Gabby's stomach. She went over to her computer and began looking at Gabby's records as Kelly helped her sit up.

"Ms. Dawson, I'm not going to lie to you. Your aneurysm does make things more complicated. But the good news is that it's relatively small, and we're already aware of it, so we can monitor it throughout your pregnancy. If it grows, it may cause some issues, but as long as it remains stable, I think you'll be able to have a relatively normal pregnancy," the doctor informed Gabby. "We'll monitor you a bit more closely than usual, of course, but other than that, the pregnancy shouldn't impact you at all."

Gabby sagged against Kelly with relief. "I can continue with the pregnancy?" Gabby asked, her voice thick with unshed tears. She wanted to be sure she'd heard correctly.

The doctor smiled at her. "Yes; given the size of the aneurysm, I don't believe termination is necessary."

"How dangerous is this for Gabby and the baby?" Kelly asked. "And what if it ruptures?"

The doctor gave him a sympathetic smile. "There's a 90% chance that Gabby will have a completely normal pregnancy." Her face grew serious. "I'm not going to sugarcoat things; if it did rupture, there's a very strong possibility we could lose both Gabby and the baby. But Gabby will be closely monitored throughout the pregnancy, and the aneurysm will be checked frequently to ensure it remains stable. One perk of that for you both is that it would means more ultrasounds than normal, which means more opportunities to see your baby."

"What happens if it doesn't remain stable?" Gabby asked, trying to keep the nervousness she felt out of her voice.

"It depends," the doctor replied. "As long as it's not growing rapidly, we'd continue to monitor it. However, if it would get to a place where it's no longer safe for you to continue with your pregnancy, then I would likely recommend either terminating the pregnancy, or, if you're far enough along, delivering the baby early."

Kelly couldn't stop grinning as he drove them back to his apartment. While he still had concerns about how safe the pregnancy was for Gabby, the doctor had relieved the majority of his concerns with her reassurances. They weren't out of the woods yet, of course, as everything relied on the aneurysm remaining stable enough for Gabby to carry the pregnancy to term, but the doctor seemed fairly confident in her abilities to help Gabby do so.

"You look like a cat that swallowed a canary," Gabby teased. "One look at your face and everyone's going to know something's up."

Kelly laughed. "Good thing I'm not back on shift until Monday," he replied. "I promise I'll keep it a secret. No one except Boden."

"We don't necessarily have to keep it a secret," Gabby replied. "I mean, the main reason I didn't want to tell anyone yet is in case the appointment didn't go well."

"Do you want to tell people?" Kelly asked.

Gabby shrugged. "Honestly, I don't know. Eventually people are going to find out that I'm in town, and they're going to wonder why. And then there's the fact that my OB is at Chicago Med just increases that risk; you know how quickly the rumor mill works, especially among the Molly's crowd. People talk." She paused, then added, "That is still where everyone hangs out, isn't it?"

Kelly nodded. "Yeah, it's still as popular as ever. I would know; I've been there pretty much every night since I got back from New York," he said wryly.

"I mean, it's up to you. They're your coworkers and friends, Kelly," Gabby told him.

Kelly glanced over at her, surprised. "They're your friends, too, Gabs."

Gabby sighed, shaking her head. "The last time I heard from anyone other than you was over a year ago, Kelly. I heard about Otis's death, Cruz's wedding, your and Stella's engagement, and that's pretty much it."

Kelly was surprised. While he hadn't kept in touch with Gabby much, he'd assumed the others had. He should have known that wasn't the case considering she hadn't known Casey and Brett were together, but he hadn't thought about it. "I'm sorry we didn't do a better job at keeping in touch," Kelly apologized softly. "I'd just assumed that everyone had kept in touch with you. You haven't even heard from Herrmann?" he questioned, knowing how close the two of them had been before Gabby had left.

Gabby shook her head. "Not in a while. But it's okay; I get it," she said. "Everyone's busy with their own lives. It's inevitable that people would fall out of touch as long as I've been away."

"What do you think about going to Molly's tomorrow and seeing everyone?" Kelly questioned. "As long as you're feeling up to it, of course," he quickly added. "We wouldn't have to tell anyone anything yet, but it might be nice for you to see everyone again."

"I don't know, Kelly…" Gabby hesitated. She was sure that she was ready to see everyone, or that she even had the energy to see everyone. "Maybe in a couple of weeks? Once my nausea hopefully calms down? I'm not sure Molly's and all of its smells are the best thing for me right now."

When Kelly had asked the doctor about her all-day morning sickness, her doctor had told them that it should be calming down soon now that Gabby was in her second trimester. She'd also prescribed a stronger anti-nausea medication and given Kelly a list of signs to watch for that would indicate Gabby would need to go to the ER.

"Of course," Kelly replied, not wanting to push her. "I should have thought of that; I'm sorry." He pulled into his parking spot and shut off the car and turned towards Gabby. "What about Casey?" he asked hesitantly. Telling Casey had been on his mind nearly non-stop the past couple of days. Casey was his best friend, and with him being Gabby's ex-husband, Kelly wondered whether they owed it to him to tell him before he found out from someone else. "Should we tell him?"

"I don't want to cause any issues between the two of you," Gabby stated hesitantly. She wasn't sure that she owed it to Casey to tell him considering he hadn't bothered telling her about Brett, but knowing how close he and Kelly were, she didn't want to impact their friendship at all.

"Gabby, look at me," Kelly commanded. Once she did so, he continued. "If Casey has a problem with the fact that you and I slept together, that is not your fault. I don't want you to blame yourself. But you and Casey have been divorced for almost four years now, and he's with Brett. He has no right to be mad at either of us, especially after he couldn't be bothered to tell you about his relationship with Brett. But," he added, "if it makes you feel better, we can tell him before we tell everyone else."

Gabby thought for a moment before shaking her head. "No, you're right. I'm sure Brett will tell him. We don't owe him anything other than that."
