"So." John began.
Sherlock ignored running his eyes through the paper trying to find something interesting. He was hoping to find something that could be the real reason for Adler to be in town. Some exposition, some auction, some famous public figure giving a party at his or her house, opening the place to thieves, but nothing looked suspicious or even remotely interesting for a thieve, especially one of Irene's caliber. Of course, there could be something that wouldn't show in the paper, which was more likely.
"Aren't you going to tell me anything?" John tried again.
"About what?" Sherlock asked absentmindedly.
"Oh, how about how Irene Adler ended in your bed last night."
"She broke into the flat. I found her here when I got back from Scotland Yard."
"And..."
"I'm sure you know how these things work, John."
"I thought you hated her."
Sherlock raised his eyes and looked curiously at John. "Hatred is irrational, John. It gets in the way of proper thinking. Adler is an adversary, a very clever criminal that I will put away eventually."
"She was here. At your mercy. Why didn't you call the police?"
"I have nothing that can prove her connection to any crime. Call the police would be just a waste of time. The logical thing to do is to wait until she acts again and makes a mistake."
"So you've decided to shag her instead." John stated. "I'm sorry, but how's that logical?"
"Well, she thought of that, not me. I don't know what her game is yet, but I assumed the better way to find out was to play along. It was pleasant, and very useful."
"Useful?"
Sherlock smiled. "Yes, useful. I know her better now. Small things, marks, scars. That might be useful in the future."
"Yeah, I'm sure that when she was screaming your name at three in the morning all you could think of was getting information." John said with sarcasm.
Sherlock sighed and ignored John's remark. It was pointless to get into that juvenile discussion.
"So, are you going to see her again?"
"Of course. She can't stay straight for long. I'm quite sure she'll be involve in a very interesting crime very soon."
"It's not what I meant." Sherlock just looked at him without understand. "I've known you for some time now and this is the first time I've seen you interest in someone like that."
"What, on earth, are you talking about? I've been interest in criminals ever since the first day you met me, John." Sherlock said.
"In a woman, Sherlock. I've never seen you interest in a woman before. I thought girls weren't your area... well, I thought no one was you're area, actually. But it's nice to see that you are, well, human, after all."
Sherlock just puffed and continued his research.
