A/N: First Sherlock fic after just getting into the fandom. This is set during The Empty Hearst, so there are spoilers! No pairing right now, but will be Johnlock soon.
Sherlock has never been so relieved in his life as he is when John opens his eyes and looks up at him. His hand is pressed against John's cheek, Mary leaning next to him, her fear mollified at she realizes that John is all right.
"Right, you're okay." Sherlock speaks comforting words to John, but also for himself, as he helps John into a sitting position. His heart had stopped when he realized that John was under that bonfire and a dozen different scenarios ran through his mind with their various outcomes and consequences. He needs the reassurance as much as John does.
Sherlock sits back and lets Mary coddle John, speaking sweet words to him. When it appears that John has regained his composure, Mary helps him to his feet. "Let's get you home now." It takes a moment for John to stand sturdily, but Sherlock's hands are poised and ready to catch him should he stumble.
It takes everything that Sherlock has to let Mary hold John while he follows behind.
Sherlock pulls ahead of them at the last moment, reaching the sidewalk first, putting his hand in the air to hail a taxi. As the car pulls over to them, he holds the door open. Mary helps John into the back seat, his balance and focus not quite fully returned yet.
"Now you." She stands back expectantly, her eyebrows raised as if to challenge Sherlock to not come with them.
"Mary." He likes her. She's clever. "Take him home."
She doesn't speak or move, not backing down.
Sherlock holds for a moment, considering if it's really worth it to go up against her where John is concerned. He decides that it isn't and gets in the car. She follows, not trying in the slightest to hide her victorious smile. "221B Baker St., please."
Sherlock looks over at her, a puzzled expression on his face.
"You said 'home', didn't you?" Her smile never faulters as she maintains eye contact with him.
Sherlock can't help but smile back at her. Yes, he definitely likes her.
