Sherlock was clearly annoyed, He was sure it was going to be struggling to even want to work with her. It was never easy for him to even deal with new people. He had never been good with people.
He was just waiting for Lestrade to get on with explaining the case. He hoped it was something interesting. He was rather bored with normal conversations right now. He leaned on the wall tapping his foot.

"Mmph." The detective muttered. He knew he was never patient with people. He couldn't help that, He was just Sherlock. He was also easily bored if the subject wasn't about cases. His interest sparked when the case was mentioned.
"Ah finally something interesting, " He returned his gaze from the window back to Lestrade. 
"There has to be a reason that it was only men." His mind seemed to be working hard. He was trying to see what he could work out from that infomation.He knew he needed to see more of the evidence of the murders.
He knew he always worked it out in the end. Even when it was hard Sherlock could make it look easier than it was.

"Of course I want to see them, " Sherlock rolled his eyes and looked at Lestrade. He needed to, it helped give him clues. He knew he could work out alot from seeing the bodies. He was ingoring the pain that he was in. He could take a painkiller, but he wanted his mind to be clear. He also was to busy worrying about the case to be worried about his own pains. The detective was looking at her "Food slows me down, don't need breakfast."
He knew that wasn't true, he was rather hungry, but he wasn't giving into it, He hardly ever did. John sometimes had to force him, or hunger got too much and he gave in and got food, but he mostly waited until after cases.

Yeah right Sherlock thought, he didn't want to believe her there. Working with another detective wasn't something that could go well in his opinion. "Nobody can be a second John." John was his best friend and nobody else had ever meant that much to him. He was so terrible and making friends, He knew he probably couldn't be friends with Mae so easily.
He huffed "Your stuck with me, I don't have to like it." There was a harshness to his voice. He knew there was no way that he could be ok with this at all. He was looking around . He doubted he even needed the help.
