Hey guys here is Chapter 4! Sorry for the long wait I'm working on a future chapter for this story as we speak so PLEASE review and let me know what you think. I asked nicely haha. So read, review and enjoy :) I only own Kaitlyn and Aiden!

"Hey is everything ok?" Dave asked as he ran into the room on the Pediatric floor that Aiden was moved too.

Haleh gave him a mask to put on as he walked closer to Aiden's bed.

"Yes he is fine now. He had a major asthma attack. Carter did a chest x-ray to rule out any other illnesses that could have triggered it and gave him a breathing treatment." Kaitlyn said as she rubbed her sons head as he held the tube in his mouth that was giving him the treatment.

"It's my fault. I shouldn't have come to your apartment. I'm the reason my son had an asthma attack." Dave said in a panicky voice.

"Baby, Momma and Daddy will be back alright?" Kaitlyn asked Aiden as he nodded at her. She touched his head once more before she pulled her ex out into the hallway.

"Dave you didn't let me finish. It wasn't from the flu. Somehow he got bronchitis, so calm down." Kaitlyn said as Dave took off the mask and took a breath. "Breathe. He's okay and it's not your fault." Kaitlyn said with a laugh as she touched his shoulder.

"Sorry. It's just after two years of not doing anything for him when I finally do see him I thought I got him sick. I want to be a good father Kait." Dave said as he looked up at her with sad eyes.

"You are Dave. You are sick and you quickly got back up here to see him, and then you freaked out because you thought you got him sick. You were concerned for him. If you weren't a good father you would've ignored the call and sat home and nursed yourself instead of risking getting sicker by coming out in the cold. You are a wonderful father Dave." Kaitlyn said with a smile as Dave looked up at her.

"You think so?" Dave asked with a hint of a smile.

"I know so. Now don't let it get to your head ok?" Kaitlyn said with a laugh. "Now go back home we don't need you infecting the ER." She added as she began to walk back into her son's room but was stopped by Dr. Weaver.

"Kaitlyn, Dave. May I have a word with you two in my office?" She asked as she walked away from them quickly.

Kaitlyn looked at Dave with wide eyes as the former couple followed their boss into her office.

"Kaitlyn it says here you ordered a flu test so that Dave could be sent home?" Weaver asked as Kaitlyn and Dave sat down at the desk.

"Yes m'am."

"It also said you signed off his chart and gave him a doctor's note. Why did you do that? Did he put you up to it?" Weaver asked as she glared at Dave.

"No he didn't. He was dehydrated and he got sick all over triage. Would you want him collapsing or vomiting on a patient?" Kaitlyn asked as Dr. Weaver looked at her with wide eyes.

"Well no…"

"I only did what I thought was best. Dave came to me complaining about his symptoms, I saw first hand how sick he was and I treated him. Isn't that what they taught us in med school?" Kaitlyn asked as Weaver still looked in shock that she was standing up to her.

"Yes they did Mrs. Malucci I agree. I'm letting you off with a warning this time. Just because you two are married doesn't mean you can clear each other to go home. Next time run it by me Kaitlyn." Weaver said as she stepped out of the office leaving Dave and Kaitlyn alone.

"Nice standing up to Weaver. Guess she will hate you now and let up on me." Dave said with a laugh as Kaitlyn shook her head.

"I'm a Malucci so I guess it's expected." She said with a laugh as Dave walked closer to her.

"Well I'm going to go back with Aiden maybe Miss. Bitchy will give me the rest of the day off. Go home and rest I'll call to check up on you later." Kaitlyn said as Dave nodded at her and grabbed her arm stopping her from going out the door.

"Dave what…" Kaitlyn started to ask but stopped short when Dave pulled her into his arms.

"Thank you."

"Um… you're welcome? Why are you thanking me?" Kaitlyn asked as Dave hugged her tightly.

"For not acting like a total bitch since you came back, for helping me when I was sick and for giving me a handsome son." Dave said as Kaitlyn pulled back and looked at him.

For the first time in the four years that she had known Dave, Kaitlyn saw sincerity in his eyes. He was still the same cocky, smartass Dave but she had to admit he had grown up during the time that they had been apart.

"You're welcome Dave. And thank you for giving me Aiden."

Before Kaitlyn could say anything else Dave gently kissed her lips. Kaitlyn closed her eyes and kissed back melting in his familiar touch.

"Dave no." Kaitlyn said finally pushing him away.

"Why not?" Dave asked with a groan as Kaitlyn walked towards the door once more.

"You aren't going to trick me Dave. You know what gets to me so you do it and I won't fall for it again." Kaitlyn hissed as she quickly walked back to her son's room.

She was there for a few minutes before Carter came in the room with a piece of paper in his hand.

"Everything ok?" Kaitlyn asked as Carter gave her a smile.

"Yes everything seems normal. After he finishes his breathing treatment he can go home. Have him take this every four to six hours until his bronchitis clears." Carter said as he handed Kaitlyn the prescription.

"Thanks again John. Listen Weaver wouldn't let me have the rest of the day off so would you like to go for lunch in thirty? You know as a thank you?" Kaitlyn asked as Carter looked at her with a smile.

"I'd like that."

"Okay I'll meet you in the ambulance bay in thirty minutes." Kaitlyn said as Carter smiled at her and left the room.

~Later~

"Hey." Kaitlyn said with a smile as Carter walked towards her.

"Hey. How is Aiden doing?" Carter asked as Kaitlyn pulled her jacket around her tighter.

"He is doing a lot better. Cleo just discharged him. My mom is taking him till I get off tonight." Kaitlyn said as she took Carter's arm which he was holding out.

"That's great. Remember to bring him back at the end of the week to see if the medicine is working." Carter replied as he opened the door to Doc Magoo's, the small restaurant across the ambulance bay that the ER doctors frequented.

The two took a seat at the table near the back and the waitress took their drink orders.

"So tell me all about yourself." Carter said with a small laugh as the waitress brought them their coffee.

"I'm not all that interesting John, trust me." Kaitlyn said as she took a sip of her coffee.

"Try me."

"Okay. I'm from Massachusetts. I'm a third year resident hoping to start in Pediatrics. I'm twenty seven and have a two year old son; I'm separated and can't wait to be divorced." Kaitlyn said with a laugh as Carter gave her a smile.

"Boston?" Carter asked as Kaitlyn nodded at him.

"I grew up in Dorchester, a neighborhood in Boston. I love my hometown don't get me wrong but I'm glad I'm out of there." Kaitlyn said as she looked at the menu.

"What about you and Dave? How did you guys meet?" Carter asked as Kaitlyn looked at him with a raised eyebrow.

"John, do we really need to get into that? I want to forget about it honestly." Kaitlyn said as she took a bite of her salad that the waitress had brought her.

"I'm just curious. I mean you just show up and say that you are married to Dave, which shocked everyone. No one would ever expect him to be married, especially to a sweet girl like you." Carter said as Kaitlyn looked down at her food.

"When I was in high school I got a scholarship to study medicine in Grenada. When I graduated that's where I went. My parents didn't have the money to put me through med school here so I jumped at the chance. Everything started out well then after a couple months my roommate and I went to a party and lo and behold guess who was there?" Kaitlyn asked as Carter gave a small laugh.

"Dave?"

"Ding ding ding." Kaitlyn said with a laugh as she took another sip of her coffee. "Dave says he went for school but we all know he didn't. He went for the beach, partying and girls. The night we met he was drunk as could be and me being the nice person took care of him. After that night he started asking me out as a thank you. I said no every time but he wouldn't stop. Finally I said yes to shut him up and we went out. We got to know each other and I fell for him hard. We started dating and then two months into the relationship dumbass said 'Let's get married!' and me acting like a love struck teenager said yes, and then I think you know the rest of the story." Kaitlyn said as Carter looked at her with a blank expression.

"I think if we didn't get married we would still be together today. It just happened so fast then it was over so fast. I regret getting married every single day, but then I stop and think if it wasn't for Dave I wouldn't have Aiden. So it's a love hate relationship." Kaitlyn said finally looking up at Carter.

"Do you still love him?" Carter asked taking Kaitlyn by surprise.

"Honestly? Yes and no. I want to believe that he has changed but I think of all things that he has done to hurt me and I convince myself that I'm not, and then I think of all the good times we had. Honestly, I really don't know." Kaitlyn said with a shrug as Carter just looked at her.
