A/N: This is my first Rizzoli & Isles fic so be gentle. "Missing scene", set during 4x04 "Killer in High Heels" as Susie finishes collecting Maura's clothing and leaves her with Jane in the interrogation room. Oneshot. Jane/Maura.

Promise Me

"I'm so sorry, Maura," Jane said quietly.
"Don't be, you didn't do it," Maura shifted her arms to pull the Boston Police Department issued jumpsuit closer to her chest.
"You didn't either." It broke Jane's heart to see her best friend, usually so cheerful and full of life, reduced to a common criminal in her own interrogation room, almost naked and her eyes brimming with tears.
"Maybe I did," she offered hopelessly, wrestling with tears and frustration. "I've got a void in my brain where there should be a memory, and I've certainly experienced the kind of rage that it would take to inflict that kind of injury."
"Just don't say anything else okay." Maura nodded in response, "Come on," Jane continued, taking the folded jumpsuit from her arms so that the medical examiner could remove her underwear.

Jane looked away as Maura slowly bent down to slide off her black underwear and placed it in a large evidence bag. "Jane," Maura requested, tugging slightly at the jumpsuit in her arms. Releasing it, Jane watched as her best friend slipped into the white uniform, pulling it up to her waist before stopping suddenly, placing her hands on the table and staring down at the cold steel. A few moments passed before Jane heard soft sobs. She watched Maura's hunched shoulders shake as she cried.
"Maura," Jane placed a hand on her bare shoulder, pulling her slightly towards her. Maura took the invitation and spun around, directly into Jane's arms. Jane wrapped her arms around Maura, holding her tightly; she kissed Maura's hair, distinctly aware that she was almost naked from the waist up, and that one hand was delicately tracing Maura's spine as the other hand snaked its way around her shoulders. The doctor cried softly, her hands covering her face in disbelief. Jane's chest ached; a deep longing grew in the pit of her stomach, a mixture of denial and desperation.
Jane leaned back slightly and moved Maura's hands, holding one hand in her own, intertwining their fingers, and cupped her cheek with the other, wiping away tears with her thumb. "Maura," she whispered, looking directly at her, "Maura look at me," she blinked away tears. Maura opened her eyes, allowing tears to fall freely, and looked into Jane's eyes. With inches barely between them, Jane closed the gap, drawing Maura's lips towards her own, turning at the last second to kiss the corner of her lips. She felt Maura completely relax, linger there, and felt Maura return the pressure, kissing Jane softly. "Maura," Jane whispered again, eyes closed and leaning forehead against forehead. "I'm not going to let anything happen to you."

Maura placed her arms on Jane's hips, clinging to the detective's shirt beneath her jacket. "Promise me something," Maura said.
"Anything."
"Promise me that if," she hesitated, pulling away from Jane, "Promise me that if the evidence proves…"
"Maura, no," Jane interrupted, cupping her face with both hands.
"Just promise me that you'll do the right thing!" Maura said sternly. Jane looked into her eyes with disbelief and fear, and something else that ached inside her chest. Maura cocked her head to the side, smiling weakly through tears. "It'll be okay," Maura whispered.
Jane closed her eyes against tears, and slowly moved her hands from Maura's cheeks, down to her waist, and pulled her tightly into her arms. "I promise," she said feebly, tightening her arms around her small waist.

Eventually, Maura took a step backwards, deciding that it was time to get on with things before the entire BPD came looking for her. Jane sat on the edge of the table and folded her arms, biting her thumbnail anxiously.
Maura reached behind her and unclasped her bra, letting it fall on to the table before placing it in the evidence bag. She pulled the jumpsuit up, sliding her arms into it and buttoning it up. "You know this outfit isn't particularly flattering, but with a few modifications here and there the prison system might really be onto something."
Jane looked up, eyes wide, "First of all, I don't think they call them outfits in prison, Maura," exchanging glances, "Second of all…" Jane stumbled, giving up, and let out an exhaustive laugh. Maura's eyes glistened with a smile briefly.

Suddenly, there was a knock at the door. Jane looked into Maura's eyes, silently resolving to do absolutely everything in her power, and even more, to clear Maura's name. They held each other's gaze for some time. There was another knock at the door, snapping them out of their moment. "Yeah," Jane answered as two uniformed officers entered.
"Time to go," Maura said before walking around the table towards the door.
"Maura, wait," Jane quickly followed Maura and the two waiting officers, refusing to let anyone else escort her to the van.

Downstairs, a police van waited, and as Maura was led into the back, Jane stood in the doorway to the parking lot, watching nervously. Just before the officers closed the doors, Maura looked up, holding Jane's eyes. And then she was gone.

A/N: Be gentle!
