Three Days

Thud. Thud. Thud. Slam.

"C'mon Locksley, off to bed"

Sherlock's head lolled to the side, his body sagged against the smaller blonde's.

He mumbled something unintelligible, trying to walk away from her, but she held fast.

"No no no, you're staying right here" She grunted, pushing him on her bed.

She just got a trash bin under his chin when he vomited violently.

Leena locked the door, moving next to her retching best friend, rubbing his back gently.

You'll be OK Locksley" She said, sighing quietly "You'll be OK"

DAY 1

Sherlock woke up in a groggy haze, his vision blurry.

His body ached, his head buzzed and he could only think of one thing; his morphine.

The effects of his last hit was wearing off already, and he needed that blissful feeling again. He clawed his way to the edge of the bed, stumbling to the door and reaching for the knob blindly.

The locked door clicked.

Sherlock's brows furrowed, and he tugged on the door harder, the lock rattling.

"Its locked, you're not getting out"

Sherlock turned, blurry eyes staring at Leena, who was sitting in the corner, a tray of breakfast on the small table beside her.

That's when he realized; this wasn't his room.

"Leena" He grumbled, stepping closer to her.

The burn in his veins and the itch of his skin was getting worse as his head slowly cleared.

"Where are my drugs?"

Leena sipped her tea, her face level.

"At your house."

"And where are we?" He said, anger slowly building in him.

"At my house"

And that's when the tray flew out the window.

DAY 2

He was curled up in her bed, his hair a mess, vomit on his clothes, eyes blood-shot and leaking tears.

"I-I can't Leena" He sobbed, fingers curling into her shirt.

"Yes you can Sherwood" She whispered, stroking his hair.

He sobbed into her chest while she comforted him, reciting quiet lines of poetry to calm his down.

He fell asleep in her arms, her fingers gently entwined in his curls.

She smiled at him fondly, laying him down and covering him.

When Sherlock woke up again, he was in a fresh shirt, his face washed, and tucked in.

Leena was slumped in a chair, fast asleep. A hot cup of tea and toast was on his bedside, and he allowed himself a small smile.

Leena... he thought, looking at her through watery eyes.

What would he do without her...

DAY 3

Sherlock woke up and immediately stuck his head in the trash bin beside him, retching noisily.

"Your fault, all you fault" He groaned in between, glaring at Leena.

She shrugged. "If you hadn't thrown your life away for boredom, we wouldn't be here"

"I didn't do this! I didn't lock myself in this damn room you ruthless bitch-"

"I am saving your life Sherlock Holmes!" She shouted, glaring at him.

Sherlock scoffed, setting the bin down and rolling his eyes "I was fine before. I was in control-"

"Passing out in a pool of vomit is not 'in control', Sherlock. Its drowning." Leena got up, walking towards her friend and dragging him to her bathroom, quite unceremoniously. She turned on the shower, letting the freezing water run for a moment.

"And Damnit if I'm not gonna save your sorry ass" Then shoved his head under the cold stream.

"You damned woman!" He screamed, thrashing against her hold.

Leena just held tighter to his neck, nails digging in so hard they drew blood.

"You are so lucky you have me Sherlock" She growled, her anger rising.

He just ignored her, continuing to scream profanities at his life saver.

Eventually, Leena just locked him in the bathroom, unlocking the door after 20 minutes.

A sopping and very angry Sherlock said nothing, just reached out and slapped her, his anger uncontrollable.

Crack

"How fucking dare you!" She screamed as Sherlock clutched his broken nose.

"I have been saving your ass for weeks! I should have left you out in the gutter!" She screamed, throwing pillows at him.

Leena had back him against the wall, nose to nose with him.

"Don't you ever raise a hand to me again Sherlock Holmes" She hissed, her eyes glittering with both hurt and angry tears.

Sherlock nodded, dazed.

He fell asleep with blood on his shirt.

DAY 4

When Sherlock woke, he knew this was the worst day.

Because Leena wasn't sitting in the corner, and the door was open.

Leena was standing at the counter, flipping through a magazine and sipping tea.

"Leena"

The blonde girl stiffened a bit a the sound, turning to him.

"Sherlock"

The pair stared at each other a moment, then Leena was in Sherlock's arms, both of them holding onto each other like they were going to disappear.

"Next time, I'm leaving you in the gutter" She sniffed, knowing she had her best friend back.

Sherlock smiled, holding her tighter "There won't be a next time"

"Good"
