He still doesn't know the full story of Irene and Moriarty. He is unsure how much he really does want to know. She was a criminal, she came and she went, she got in trouble with many high-authority persons throughout the entire world and was paid for it with thrill, excitement, and riches. She did what she did out of desire and nothing else. Yet for someone so irrational, it seems, so incredibly impulsive, she was miraculously logical and smart enough to trick Holmes on more than one occasion.

In the end, though, it was betrayal. No matter what mind might say that she may as well be the only reason he was alive today. She found him so close to the end and she was the only reason Lestrade came to clean him up and send him off before anyone knew that Sherlock Holmes got away. She was also the only one who knew the progress he was making; the only way Moriarty could have known what he knew.

He couldn't help a short laugh before letting his hand slam down on the table perhaps a little more strong than he initially meant for it to. "Adler works for Adler. Moriarty drew her in with his promises, and he won."
