I must say I am completely puzzled by what happens in a "Study in Green".

Holmes somehow gets transported into a massive pyramid tomb level out of the game "Tomb Raider".

What exactly happened here? Are we to think that he has supernatural powers now to go into the past?

How does he figure out what happened in the past and who betrayed who? He can see exactly what happened many years ago? How is this possible?

I am just confused what the creators of the game want us to believe.
