What do they fight over:

"Amy, I don't want to tell you what to do with your life, but, seriously, this needs to stop," Jake pleaded with his girlfriend.

"I've had a rough day," she snapped back.

Jake tilted his head and rolled his eyes. "It's ten in the morning."

"Yeah well, I had to take a cold shower because someone used up all the hot water. That same someone also finished the last of the coffee. And, then, after I spent the morning briefing everyone on two of my cases, the Vulture swoops in and takes them both," Amy practically yelled at Jake. "I...I just...I need this," she said, holding up the cigarette Jake had caught her smoking on the balcony just moments earlier.

"I'm sorry about the shower and the coffee. And I know there isn't anything I can do about the Vulture, but let me help you relieve your stress. Please stop resorting to smoking. It's so disgusting, not to mention really bad for you." Jake took a step closer to Amy, holding out his arms to embrace her.

"Are you seriously lecturing me about taking care of myself?" Amy sidestepped away from Jake's open arms.

"Ames…" Jake started.

"What? I'm killing myself?" Amy interrupted him, guessing what he was about to say. "It's not like you take such good care of yourself. You eat a very, very unhealthy amount of junk food. You never go to the doctor…"

"Alright, I get it," Jake snapped, cutting her off. "I don't want to argue with you so I'm just going to go back to work." He turned away from Amy and opened up the door, ready to walk back into the precinct.

"Walking away from a fight? How mature? Well, what did I expect when I started dating a man-child?" Amy continued, unable to drop the argument.

Jake slammed the door shut, turning back around to face Amy. "A 'man-child?' Really?"

"You have the diet of a ten year-old left alone in a candy store. Everything is a joke. You're still in debt."

"Crushing debt." Jake said sarcastically, immediately regretting his comment.

"See? Still making jokes. You can't even have a mature conversation." Amy threw her finished cigarette butt into the ashtray and took a step closer to Jake, her fists balled up at her sides. Tears threatened to fall from her eyes, but Amy fought to hold them back.

"This isn't a mature conversation. This is you pointing out everything that you don't like about me," Jake angrily replied. "You're in a bad mood, and you're taking it out on me."

"I'm not taking my bad mood out on you. I'm just tired of always having to be the mature one in this relationship. The one who takes care of our finances, who looks out for our health..."

"Well I'm sorry I'm such a burden on you," Jake retorted. "I thought we were a partnership. I didn't realize that you saw me as someone to take care of."

This wasn't the first time that Jake and Amy were having this fight. They would yell at each other about their flaws until one of them did something funny or made a joke, breaking the tension, allowing them to apologize and make up. They were having the fight more and more often though, and Jake was worried that one day, they wouldn't be able to get past it.

Amy just stood there, staring at Jake.

"Nothing else to say?" Jake asked.

"I...I…" Amy stuttered. A tear escaped, flowing down her face. She quickly wiped it away, hoping Jake wouldn't notice.

"Is this about something else?" Jake asked, sensing there might be something bigger bothering Amy.

As the two stood there, quietly staring at each other, their silence was broken by the sound of the door opening up. "Jakey, we need to go look into a case," Charles yelled to Jake.

Jake nodded, his back turned to Charles as he continued to look at Amy.

"Go," Amy sternly instructed Jake, walking past him and back into the precinct.

Jake let out an annoyed sigh, spinning around. "Let's go Boyle."

Jake and Charles' case was tougher than they anticipated, keeping them out of the precinct for the rest of the day. Finally, Jake went home, surprised to find that Amy wasn't home yet. Knowing that cases often kept them at work late, Jake wasn't too worried by Amy's absence.

He made himself a sandwich, sitting at the kitchen counter with a book while he ate. He was so absorbed in his book, he didn't even hear Amy come in.

Jake looked up to a box of nicotine patches and a pack of nicotine gum being slammed on the counter in front of him.

"Shut up," Amy said, walking back around the counter.

"I didn't say anything," Jake replied, turning on the stool and opening his arms up to Amy. She walked into his open arms, throwing her arms around his neck and burying her head into the crook of his neck and his shoulder. As he wrapped his arms around her, he heard her begin to sob and felt his shirt soaking up her tears. He rubbed her back, not saying anything, just waiting for her to open up to him.

After several minutes, Amy pulled back, tears still streaming down her cheeks. "The cigarette this morning was because my dad had another heart attack. It's pretty serious this time."

"Ames," Jake comforted her, pulling her back in for a hug.

"I wasn't ready to face that my dad is sick and I picked a fight with you. I'm so sorry."

"You don't need to apologize Amy."

"I can't keep taking my anger out on you. You deserve better."

"I can't do better than you Amy. I'm a 'man-child' who really struggles to take care of himself. Seriously, what are you doing with me?" Jake laughed.

"Ugh,"Amy groaned. "I'm sorry for calling you a 'man-child' and everything else I said."

"It's fine, you're right."

"No, Jake, I'm not, I was out of line…"

"Amy, stop. We're not going to fight about this, you have more important things to worry about."

"I'm so lucky to have you," Amy smiled as she hugged Jake tighter. "I promise, I'm going to quit," she said, stepping back, gesturing to the nicotine patches and gum.

"Its okay, Ames. I had no right trying to tell you what to do with your body," Jake insisted.

"You're just trying to look out for me. And I appreciate it," Amy reassured Jake. "I love you."

"I love you too."
