História Winchester's go to London - The conversation:

Sherlock and I finally makes it to the third crime scene. We had to make a pit stop by the flat to get something because I left my jacket. Immediately stepping out of the cab...Lestrade was right there. He said "The two FBI agents are here waiting to talk to you."

"Where?" Sherlock said.

"Over there by the body." Replied Lestrade who was pointing over there at the group of three.

"You said two agents. How come there is three?"

"No, there's...Three?" Lestrade said who is now stunned. "Well they only told me that there was going to be two. Didn't mention a third one."

"Good are we done with trying to to figure why they lied? Take us to them Lestrade." Said Sherlock.

Lestrade and I once again exchanged glances before he took us over to them. When we got there, Lestrade held out his hand.

"Detective Inspector Lestrade."

"Dr. John Watson." I said shaking hands with each of them. Well two out of the three. The other looked at my hand like it was an alien.

    The tallest one of out of the three said "I am Agent Vincd and this here is my partner Weber. The man next to him is his replacement agent Novak."

"No, your not." Said Sherlock.

"Who might you be to criticize the authority?" Said agent Weber.

"This is.." Said Lestrade.

"What's your real names?" He said again. Only this time he interrupted Lestrade.

"Did you not hear us. Agent Weber, Agent Vince, Agent Novak."

"Your real names not these alias. What's your name or I am not talking to you." He stated.

"OK, fine. We will play your game. My name is Sam and this Dean. The fellow next to him is Castiel.”

"How was the flight?""

"What flight?" Asks Sam

"The flight over here to London."

"It's..."

"Whoa...whoa...whoa. how did you know that we took a plan over here?"

"I wouldn't really do that, Dean" I say to him, but he just gives me a shut the hell up look.

"Simple minded Americans...Your accent is the clear sign that you are not from here. There stress marks under your eyes that mean you haven't been sleeping. Assuming that you have a fear of planes and was worried about something at the same time. I would say you got a total of two hour sleep while your brother here had the correct number of hours..  should I carry on?"

"Who the hell are you? How do you know all of that stuff?"

"Please don't get him started" I begged.

Luckily though, all Sherlock said was " I am a consulting detective, the only one in the world. The name is Sherlock Holmes and the address is 221B Baker St. Have a nice day." Said Sherlock while walking away from the Winchesters.
