Sherlock was looking at Moriarty as he woke up. His head was pounding. He felt dizzy and wanted to lay down. He was feeling sick slightly from when he had been beaten up. The genius was very tired.
He knew that he needed to lay down and recover a bit.
The detective knew he was not in good shape.

"Ohh let him go?" Moriarty laughed. "Why should I?"

It seemed that Moriarty was enjoying this whole thing. He knew that Sherlock was beaten and exhausted. He had never seen Sherlock so weak and exhausted, He knew that wouldn't slow Sherlock down for long. The madman smirked darkly.
"Tired Sherlock?" he laughed.
Sherlock was breathing deeply, his eyes widdened and he looked around . He seemed to have just noticed Lestrade. He was shocked that Moriarty had come to free him. He didn't seem to expect that.

"Lestrade?" Sherlock questioned.

The Detective wondered if he was just dreaming. He knew his head was fuzzy from being knocked out. He had never even thought Lestrade cared enough or would risk his own safety.
