John knew Sherlock well. Actually, it would be more accurate to say that John guessed Sherlock well. It was impossible to do more than that when it came to the suave, mysterious detective. His varying moods and unpredictable temper led many to believe that he was, indeed, acting on whims and fancies. But John, the only person to get as close to Sherlock as he did, knew how to see patterns in the detective’s behavior.

Sherlock Homes was an interesting study. Once properly motivated, there was absolutely nothing to deter him from achieving his goal. Strong set of morals, too. Wanted to do the right thing, even when, on occasion, it wasn't completely legal. Payed detailed attention to personal cleanliness. Extremely intelligent and was able to know instantly what to remember and what to forget. Very observant, which led many to believe that he was, indeed, capable of reading minds. Incalculably arrogant, taking great pleasure in baffling those around him with his knowledge and insulting those who failed to keep up. When not intellectually stimulated, a state of bleak depression overtook him. Prone to substance abuse. Cold and distant (not true). And, above all, the one man Watson would ever love.
