So this is my second fanfiction. This was actually written first. This is co-written, so hopefully the two writing styles don't clash too much. Let us know what you think :)

We do not own Rizzoli & Isles, no copyright infrigement intended.

A/N This first chapter is very dialogue heavy sorry about that.

The Fight Of Their Lives

"Rizzoli." Jane answered the phone with her eyes closed.

"Dr. Isles," came from next to her and she opened her eyes.

She seemed genuinely confused at the sight beside her. "I'm on my way," Jane said, still staring at Maura.

When Maura hung up the phone she looked over at Jane. "What are you doing here?" Jane asked as she got out of the bed.

"I must have fallen asleep while I was meditating," Maura said, getting out of Jane's bed

"Again?" Jane said as she went in the bathroom to brush her teeth.

"I don't think you understand how stressful it is to argue with you." Maura said as she attempted to follow Jane into the bathroom.

"My bathroom, I go first," Jane said with her trademark smirk.

"Jane, I can taste the bacteria," Maura whined as she again attempted to gain entry. With an exaggerated sigh Jane moved aside and allowed Maura to enter.

"Jane, you should brush in a circular motion. When brushing in a straight line you miss bacteria and tar along the gum line," Maura said as they walked out of Jane's apartment.

"Maura, I know how to brush my teeth. We just so happen to have a murder to get to and I just so happen to have a manual toothbrush, not one that spins with the push of a button." Maura shook her head at Jane as they got in Jane's car.

"Jane, would you at least wait for a red light before you play with your hair?" Maura begged as Jane pulled her hair into her crime scene ponytail.

"I'm not playing with my hair Maura, I am putting it in a ponytail and anyway, we're almost there. Relax," she mumbled as she pulled up to the scene. The house was taped off; Jane peered through her windshield for Frost but didn't see him. Maura and Jane exited the car and walked toward the tape, flashing their badges simultaneously and entered the premises. Maura immediately walked into the living room and begins observing the body.

"Jane, I heard it's pretty bad in there. Frost has already made two trips outside." She nodded, clapped him on the shoulder and proceeded inside. The putrid scent of death hung heavy in the room. Jane noticed it immediately, upon entering the house, she observed the pattern of the blood spatter, it's wide, uncontrolled. She also notices the amount of blood, it's everywhere. Walking in she noticed shards of a broken vase on the ground and partial shoe prints. She continued into the house to where Frost, Korsak and Maura were gathered over the victim.

"What've we got?" Jane asked, pulling on a pair of gloves.

"Katherine Lee, age 23. She's a student at BCU." Jane looked down at the woman

"Time of death?" Jane asked looking at the bodies, "Rigor mortis has set in, it's been anywhere between eight and twelve hours. I'll be able to confirm once I've done a full autopsy." Maura answered and Jane simply nodded.

"Forced entry?"

"No, the windows are all intact and the door was closed when we arrived."

"Eight entry wounds, a kitchen knife?" she asked looking at Frost who simply shrugged.

"I can't make that determination yet."Maura replied not looking at Jane. Frost muffled a chuckle knowing the banter is sure to come. Jane stares down at Maura willing her to look up. "What?" Maura asked

"They're stab wounds Maura." Jane exclaimed gesturing toward the body, "Well I know that, but I can't infer what type of blade it was." Jane sighed and continued to examine the body, "There's another one in the kitchen." Korsak said leading the way.

The kitchen was a worse scene than the living room, "Lauren Ashley, 21, also a student at BCU." Frost informed, Maura crouched down over the body.

"These wounds look to be consistent with the other victim's."

"Is that guess?" Maura looked up at Jane and shook her head, "no, an observation." Jane smiled and knelt next to her.

"Maura look at that." Jane pointed a stray piece of hair on the victim's chest.

"Hm, the hair color isn't consistent with the victim. The hair bulb doesn't appear to be attached" Jane looked up at Frost,

"Do you have anything on these two? Did they know each other?" Jane asked as she continued to assess the scene.

"They did, very well actually. They were close," Frost said, putting the emphasis on the word close. Maura looked up at Frost and Jane raised her eyebrow.

"How close?" Jane asked as Maura looked on, genuinely interested. "This close," Frost responded, as he handed Jane a photo of the two victims kissing. Jane held the picture out for Maura to see.

"Oh," said Maura, unfazed. Jane took a moment to soak the information in. "So they were together," Jane stated.

"Looks like it," Korsak chimed in.

"OK, let's get in contact with their families," Jane said to Frost. He nodded and made a note.

Jane glanced down at Maura, "I hate this part of the job," Jane said shaking her head. Maura stood and came to stand next to Jane, rubbing her back.

"Ooo, your infraspinatus fascia is tight."

"My what?" Jane exclaimed, turning to stare at Maura in confusion.

"Your infraspinatus fascia," said Maura matter of factly.

Jane gave Maura a look and replied with "Thank you, Dr. House, now can you tell me in English?"

"It's the muscle that stabilizes your shoulder joint," smirked Maura.

"You couldn't have just said that in the first place?" joked Jane. She looked over at Maura and smiled affectionately. "Let's head to the station."
