"Sherlock?" Hazel asked. "That's a really weird name." Sam and Dean laughed. "Yeah, don't I know it," Dean said, "but Dad seemed to think this guy knows his stuff." They parked at the curb of a little street. "We're here," Sam said. He was driving because he was the only one who knew how the British streets worked. They all got out of the car and knocked on the door. An older woman answered the door. "Oh, hello! You must be the boys Sherlock told me about. Let me just go get him. Come in!"They stepped into the small apartment building. Sherlock, dear, those two boys are here," she called as she walked up the stairs. She disappeared for a moment, then a tall, thin man with dark, curly hair came down, followed by a shorter man with blonde-gray hair. Hazel took a step back until she was behind Sam and Dean, but still between them. She was very shy. The taller man stood quietly and eyed the trio up and down. The shorter man stepped forward and extended a hand towards Dean. "Hello, I'm John. John Watson. This is my friend Sherlock." Dean shook his hand and said, "I'm Dean, this is my brother Sam, and this-" Hazel took a shrunk back so that she was partially hidden by Sam. "-is Hazel.She's a little shy." Hazel gave a tiny wave as she stepped tentatively back between Sam and Dean. Sherlock smiled a tiny smile and extended his hand to Dean, then Sam, and finally Hazel." So you are John Winchester's boys.Pleased to meet you. I understand you're investigating a string of disappearances?" Sherlock asked. Sam spoke up. "Yeah, we think it might be a demon called Azazel. We've dealt with him before, but this is bigger than anything we've ever attempted before. We needed all the help we could get, and our dad had you listed as one of his contacts. We hoped you could give us a hand." Sherlock considered this for a moment, then answered. "Well, why do't we go upstairs and talk about it, and I'll see what I can do."
