a/n: Hey guys! So I came up with the idea of writing this story after watching His Last Vow for the 452347835 time. I am really unsure if I should keep this story as a one-shot or carry on writing more chapters so please review of what you think and if I should carry on. THANKS!

P.S. unfortunately I do not own Sherlock which upsets me deeply.

He stood outside her door as he rummaged through his pockets for her keys. He sighed heavily as he inserted the key into the door and turned it slowly. He pushed the door open silently before entering her flat. The door closed softly as he stumbled carefully into the darkness of the flat. His vision became clearer as a sliver of light came from her room as he walked closer. His hand rested on the door knob and he stood there in silence. Toby purred fondly as he walked closely around his legs. He looked down at the cat, lent down and ran his slender fingers across Toby's back. He smiled in amusement as the cat nuzzled his face into his palm. He then stood up straight and opened the bedroom door.

The face on the muted TV was the first thing that caught Sherlock's eye. The familiar face replayed on the screen over and over again. But this time it wasn't deliberate it was the news networks repeating news reports of the return of Moriarty that have been on every network for the past week and a half. He looked away from the TV with disgusted and looked over towards the bed.

His face softened as he saw the small frame of Molly Hooper lay in a bundle of blankets. He walked closer towards her and noticed she was clenching his t-shirt that he leaves here for whenever he stays. He walked over to "his" side of the bed and sat down softly next to her. He could see her begin to stir at the sudden weight change on the side of the bed. Her eyes fluttered open and Sherlock smiled down at her. She sat up in her bed as she smiled tiredly back at him.

"Sherlock, what are you doing here? Are you okay?" She said her voice half tired half concerned. Silently, Sherlock removed his t-shirt from Molly's grip, placed it on the floor and lay down beside her. Molly rested her head back down on the pillow beside Sherlock. She lies down on her side and looked at Sherlock with a worried look.

"What do you need?" She asked. She sounded exactly like she did back before the fall. When he turned to her for help in his darkest hour. But this time he didn't need anything from her. He needs to be there for her, to protect her. Sherlock look over to Molly and pulled her into his chest.

"Go back to sleep Molly." He said in a hushed whisper. Molly rested her head against his chest and inhaled his scent. She could hear the softness of his heart beat against her ear and drifted back into a deep sleep within minutes. Sherlock gently placed his chin on top of her head and held on to Molly close. He smiled to himself as he could hear Molly's soft breaths as she slept and before he knew it he was asleep himself, the first time in three days.

Molly woke the next morning to find that Sherlock was no longer asleep beside her. It was normal for Sherlock to disappear before Molly woke up but she hope this time he would stay. She wondered sleepily into the kitchen and stopped abruptly when she saw the slender man stood making coffee.

"Ah, good morning Miss Hooper. I have made you some coffee Lestrade called saying he needs my help at a scene in an hour and I will need your assistance." Sherlock said as he turned to face her with a bright smile on his face. He offered her some coffee and she accepted with a small smile to thank him. He then walked towards Molly's bedroom before she began to speak.

"Why did you show up at three in the morning Sherlock?" He stopped suddenly before turning around and walked back towards her.

"Because, Molly, Moriarty is back. And whatever it takes he is going to destroy and attack everyone that I love and care about. That includes you. I need to protect you, no matter what." Sherlock smiled down at Molly as she smiled back. He cupped her cheek and planted a soft kiss on the top of her head. Sherlock then strolled back towards Molly's room before shouting over his shoulder towards her. "Be ready in 30 minutes. We have a murder to solve Molly Hooper."
