Chapter Fifteen

Brett was the first to wake up the next morning at around seven am right when the sun was starting to come up. She was so excited to be there she felt like a kid on Christmas morning.

She was still laying in bed when she felt the babies start to move around, she smiled and Immediately put both hands on her bump so she could feel her babies kick and move around. As Brett was sitting there she turned to look at Casey and started thinking, 'How'd I get so lucky. Gabby lost someone so amazing and now he's mine and we have three little one's due in the next three and a half months.'

Casey looked like he was about to wake up, so Brett decided to hop out of bed and go to their little kitchen to make him some coffee, but just as she was setting in on the nightstand, she felt a hand reach out and grab her around the waist.

"Ahh," Squealed Brett as she was carefully pulled back onto the bed and into the arms of the man she loves, "Casey, you literally just gave me and the babies a heart attack."

Casey smiled before he threw his hand over her bump and cuddled it, "I'm sorry, babies. Your mommy's just really funny when she gets scared."

"No, I'm not." Playfully argued Brett.

"Whatever," Grinned Casey as she put his head in the crook of Brett's neck and tried to go back to sleep.

"Hey, mister don't go back to sleep. We have to get out and do something today."

Casey groaned, "Oh, come on Brett. We're on vacation, let's just spend the day in bed relaxing."

Brett finally acquiesced when Casey told her they could spend tomorrow doing whatever she wanted to do.

"Okay, but tomorrow I'm booking a boat ride, so we can take a tour around the island."

Casey smiled before he sealed the deal with a kiss, "Perfect."

A couple of hours later they were still in bed laying around watching movies, which is something they rarely go to do at home considering how tired they were with their jobs.

"Hey, I have a question for you." Called out Brett as she came out of the bathroom still wearing what she woke up in.

Casey looked up from his phone, "Okay..."

Brett laughed, "It's nothing too serious."

"Okay, what is it then."

"Well...Foster said something to me the other day."

Casey narrowed his eyes at Brett wondering where she was going with this, "And..."

"Well, don't you think it's weird that we still call each other our work names, even after being together for a while and being pregnant."

Casey looked at Brett and laughed, "That's it, really? I thought you killed someone or something."

Brett shook her head and smiled at her husband, "Don't you think it's weird though. Even when we're at home we still call each other Brett and Casey."

"Brett, come here." Said Casey as he motioned towards her empty spot on the bed.

Brett slowly dragged her feet before she climbed on the bed with him. Casey silently took her in his arms and sat her on his lap.

"Listen, I don't care what you call me at the end of the day, as long as you call me your's."

Brett smiled and leaned down and kissed him, "I love you, Casey."

"I love you too, Brett."

Brett looked up at Casey and smiled, "Listen, I know you said you wanted to spend the day in bed relaxing, but is it okay If we go outside and swim or layout on the patio? I mean come on, we can't get this view from cold Chicago."

Casey looked at Brett before he slowly started shaking his head, "How can I ever say no to you?"

Brett clapped her hands in excitement before she carefully jumped off the bed and went to grab her black maternity one-piece swimsuit that had no back and only side cutouts.

Casey smiled as he watched her get ready before he also got off the bed and went to put on his blue swim trunks.

After they got dressed the rest of the day was spent out on their patio which had direct entry into the ocean. The day was perfect for the both of them and ended almost as perfect except after they had their amazing dinner of Herb Roasted Chicken with Potatoes al gratin, the babies decided they didn't like it, and Brett puked everything right back up.

Both Brett and Casey were ready to call it a night after that, so as soon as they got back to their bungalow Casey helped Brett get ready for bed then he got ready himself and they both fell asleep as soon as their heads hit their pillows.

Both were in such a deep sleep the next morning around nine, that neither of them heard the numerous texts Foster and Kidd were sending Brett until Casey's phone started going off.

"Hello," Sleepily answered Casey into his phone as he squinted, trying to adjust to the light his eyes were suddenly bombarded by.

"Casey?" Asked Kidd.

"Yeah, Kidd it's me."

"Why isn't Brett answering her phone? Foster and I have been trying to text and call her since last night. Is something wrong with her or the babies? Are you alright?"

The loudness of Kidd's voice woke Brett up almost immediately after Casey answered the phone, "Who is it?" Asked Brett as she tried to sit up in the bed, which proved very hard to do by herself with her big belly in the way.

Casey looked at Brett and handed her the phone, "It's for you."

"Hello?"

"Brett? Is it really you?"

Brett laughed as looked at the phone and saw that it was indeed one of her best friends, "Hi, Stella."

"Girl, what is wrong with you? Foster and I have been trying to text and call you since last night."

Brett looked guilty at Casey as he carefully got off the bed and went to the bathroom, "Yeah, I'm sorry. I kinda got sick last night after dinner, and then Casey and I came back to the bungalow and went to sleep almost immediately after we got here."

"Oh my God, Brett are you and the babies alright? I told Casey that traveling wouldn't be a good idea for the two of you in the condition you're both in."

"Kidd, chill. I'm fine, it was just normal pregnancy side effects. I feel fine now."

Kidd let out a slight laugh on the other side of the phone, "Kelly just told me that I'm acting like your mom."

"Well, you kinda are." Giggled Brett.

"I'm sorry. Foster and I just miss you and worry about you."

"I know. It's sweet, and I love you both for it."

Both girls continued to talk about everything under the moon and sun until finally, Kidd proclaimed that she had to get off the phone or Kelly was going to burn the house down trying to make them lunch.

Casey walked into the room freshly showered just as Brett was hanging up the phone.

"You know the two of you can talk for hours." Commented Casey as he walked over to Brett, grabbed her hands, and hoisted her up so she could turn and slide off the bed.

Brett turned to Casey and smiled, "Oh, whatever. You and Severide are the same way sometimes."

"Hey, you're forgetting something." Whispered Casey as he gently grabbed her arm and spun her around.

"What?" Giggled Brett.

"My morning kiss."

"Oh, how could I ever forget that?" Said Brett as she tangled her arms behind Casey's neck and pulled his lips down to hers.

The kiss lasted a few seconds before Casey pulled away and announced that their boat tour was in forty-five minutes.

"Okay, I'll hurry." Called Brett as she grabbed her swim-suit, shorts, and maternity shirt for the day.

Exactly ten minutes later, they were out of their bungalow and walking hand in hand towards the resort concierge who scheduled their boat excursion, which lasted a little over three hours. Both Brett and Casey loved the excursion. They got to see numerous animals that ranged from dolphins, sea turtles, jellyfish, and of course one of Brett's favorite creatures, starfish. Brett took photos on her phone of everything. Casey, on the other hand, didn't seem to have as much fun as Brett. Whenever Brett would look over at Casey she would catch him just staring into space. He also seemed to be very fidgety.

"Hey, are you okay today?" Asked Brett as she grabbed Casey's hand and continued to walk back to the bungalow with him

"Yeah, why do you ask?"

"Well, you just seem kinda off today. Is your leg hurting?"

"No, it's fine. I'm just kinda tired, ya know?"

Brett looked at Casey unconvinced before she slowly answered, "Yeah."

Casey grabbed Brett's hand and kissed it before he led them to their bungalow so that Brett could take a nap before they got ready for dinner.

Brett took about an hour and a half nap before she woke up and started getting ready for dinner. Casey said they would try the other restaurant connected to the resort tonight, so Brett decided to try out the black, lace maternity dress Kidd and Foster had packed for her. While Casey wore his simple black tux he packed.

"Hey, you ready?" Asked Brett as she stepped outside on the balcony to see Casey sat in one of the lounge chairs, staring at the water in front of him

"Wow, you look great, Babe."

Brett smiled as Casey made his way over to her and kissed her cheek, "Thanks. You don't look so bad yourself."

Casey didn't respond, he just grabbed Brett's hand and gently pulled her in the direction of the door so they could make their way to the restaurant.

Brett worriedly looked at Casey, "Are you sure you're okay?"

"Brett, I'm fine. Come on or we'll be late for our reservation."

Brett just nodded and let Casey lead her in the direction of the restaurant where Casey planned their reservation.

It didn't take long to walk there, probably nine minutes in total.

"Hi, I have a reservation under the name of Matthew Casey."

The hostess quickly looked down at her iPad and found the reservation. "Of course, Mr. and Mrs. Casey, please just follow me."

Brett froze when she heard the young girl say Mr. and Mrs. Casey.

"You coming?" Asked Casey.

Brett shook her head, "Yeah, sorry I just zoned out for a minute."

Casey nodded before he grabbed her hand and led her to follow the hostess, who was currently trying to lead them outside.

Brett gave Casey a weird look before she asked, "Why are we going outside?"

Casey didn't say anything he just continued to follow the hostess who lead them to a beautiful, while secluded dinner table set right on the shore.

Brett gasped when she saw how beautiful it was, "Casey...this is gorgeous."

"I figured we could use dinner on the beach." Smiled Casey as he helped Brett sit in her seat.

"Thank you!" Smiled Brett as she took in the exceptional view in front of her.

Dinner was amazing. Both ordered the New York Strip, with a salad on the side. Brett was very happy that the babies decided to accept her food choice.

"Brett," Whispered Casey before he got up and walked to stand in front of her.

"What are you doing?" Asked Brett.

Casey stood there for a second before he reached into his tux pocket and pulled out a black velvet box.

Brett flickered her eyes from Casey's face to the box and gasped, "Casey…"

Casey quickly shushed Brett by getting on his good leg's knee and opening the box, "Brett, I know we haven't been together long, and I know that we've been through a lot, but I can't imagine going through anything in life without you by my side. You're my everything. I can't wait to become a parent with you. I love you more than anything, will you marry me?"

Brett's eyes filled with tears before she jumped up from her chair and into Casey's arms.

"So, I guess that's a yes." Laughed Casey as he tried to keep them both balanced.

"Yes!" Screamed Brett as she wrapped her arms around Casey and kissed him.

"I love you." Whispered Casey before he took the ring out of its box and slid it on to her small petite finger.

"I love you too!"
