Since I do not believe that the first season has really explained why Moriarty is capable of accessing Sherlock's mind palace and assisting him inside it, I wanted to spark a bit of a discussion about this, in my opinion, intriguing matter that will hopefully be explored further in the second season.

Do you think that Moriarty has access to it because of their shared genius and intellectual link that allows them to cognitively process things at the same speed, or do you have some other interesting theories on why it is how it is? I would love to hear them all, including your opinions on how this ability of Moriarty's could be utilised in the future when he begins to turn into more of an antagonist in Sherlock's life.
