Sherlock and Moriarty could do nothing. To be honest they didn't actually know what to do. The two girls had gone mental. Becca was kicking out, her karate training finally being used in real life. Becca looked professional, but Sadie looked wild. She wasn't really trained in this area of fighting, well, any area really, so she was just pulling Becca's hair and biting her arm. Sherlock and Moriarty looked at each other with wide eyes. Sherlock tilted his head to one side and Moriarty shrugged, both of them slowly edging away from the wildcats. The fight was a blur, until they both stopped. Sadie was holding a gun, and Becca reached into her pocket for one. As she drew it, Moriarty and Sherlock both stepped forwards. Moriarty gently prised the gun from Becca's fingers, and Sherlock carefully lowered Sadie's arm and placed the gun that was in her hand on a nearby table. The girls glared at each other, and Sherlock could see the hate and rivalry in Sadie's eyes. Becca dropped her glare, and turned to Moriarty, ignoring the look of contempt from Sadie and the look of amusement from Sherlock.

"You know, I thought you would have figured it out by now, Sherlock." Moriarty's said, tauntingly.

"I have done. There's a door behind you, leading straight outside where you can get away. Earlier, you said that it was easy to get things stored away. You and Becca keep edging towards the door and you keep looking at your watch. I've figured it out." Sherlock smirked.

"What is it?" Sadie whispered.

"This whole place is packed with bombs that are going to go off in about a minute. Well. 1 minute and 6 seconds, and counting."

"Are you actually being serious?" Sadie asked. Sherlock nodded. "Well, in that case-" Sadie raised her gun and shot Becca in the ankle, who screamed and fell to the ground.

"You... you..!" Moriarty stammered, dropping to Becca's side.

"50 seconds." Sherlock stated.

"Sherlock... what do we do?" Sadie asked, nervously. Sherlock winked, and suddenly there was a loud noise overhead, and a rope ladder dropped down in front of them. Sadie looked up to see a helicopter, with John and Mycroft sat in it. "Please tell me you didn't get them to bring a helicopter as a rescue mission." Sherlock grinned and grabbed the ladder.

"Are you coming, or would you rather blow up?" He held out his hand. Sadie looked at him sceptically. "Trust me." He said, gently. Sadie took his hand and pulled herself onto the other side of the ladder, which lifted the two of them away from the building. Meanwhile, Moriarty was trying to help Becca up, but she couldn't move.

"Becca, come on! We have to get out of here. This place is going to blow soon, I can't leave you here."

"You have to." She said, sorrowfully. "You can't die now, you have to continue making Sherlock's life a living hell, remember? That was the plan."

"The plan had both of us in it though, and I can't do it alone." Moriarty had tears in his eyes.

"You'll have to, now go, GO!" Becca cried pushing Moriarty away, who dived out of the door as the warehouse went up in flames, bits of glass and rubble shattering in the blow. Moriarty stared at the wreckage, and without waiting for the fire to die down, he ran back inside.

"Becca?" He yelled, hoping for an answer.

There was none.

He stumbled around in the smoke for a minute, before seeing her, lying on the ground, a shard of glass stuck in her chest. He fell to his knees by her side. She was breathing - slightly. Becca looked at him, and softly put her hand against the side of his face. She smiled painfully, and closed her eyes.

"No. Becca, no. Please." Moriarty begged, but it was no use.

Becca, the only person he had ever truly loved, was dead.

Moriarty looked at her for a moment. "She did this. I swear on my life I will kill her for this. I hate her. I HATE HER!" Moriarty screamed, pulling out a gun and shooting it at the now speeding up helicopter.

St Bartholomew's Hospital

Sadie woke up in a hospital bed, to see Molly, Sherlock and John standing over her. She noticed that Sherlock was holding her hand, well, he was. He dropped it and left the room, telling everyone that he was going to tell Lestrade that she was awake.

"Awake?" Sadie asked. "What happened?"

"Moriarty shot you, and you passed out. You've been out for about a week now." John said. "Sherlock carried you up the ladder."

"Sherlock carried me?" Sadie raised an eyebrow, disbelievingly. John nodded.

"He's stronger than he looks. He punched me once. I'm going to go and see if he's alright, he looked a bit pale earlier." John left, leaving Sadie with Molly.

"I'm sorry." Molly blurted out. "I didn't mean any of those things I said ages ago."

"I know, Molly. I'm sorry as well." Sadie sighed.

Molly touched the bandage around Sadie's arm. "He never left you, you know. Sherlock's stayed by your side all the time."

"Really?" Sadie asked, smiling slightly.

"Yeah. He really likes you, Sadie. And I... I think you're perfect together."

"Thanks, Molly."

Sherlock and John came back in the room.

"Can I speak to you for a second, Molly?" John asked, hinting that they should leave Sherlock alone with Sadie.

"Sure." Molly and John both left.

"How are you?" Sherlock asked.

"Fine." Sadie smiled, sitting up, and leaning her head backwards. Sherlock sat down on the edge of her bed.

"Good." Sherlock replied, for once, not knowing what else to say. He knew what he wanted to say, but he couldn't. The words wouldn't leave his mouth. Instead, he cupped his hand around the side of her face. Sadie looked at him, and smiled. Then Sherlock did something that would convey what he wanted to say.

He kissed her.

"I love you." He whispered.

"I love you too."
