At some point HBO is going to have to start subsidizing the Game of Thrones Wiki database just so the show's fans have a chance of keeping up with the ever-expanding monstrosity that is the show's lore. Even the most hardcore fans will eventually have a hard time keeping all the fictional facts straight.
I do wonder sometimes just just how much of my own brain's storage capacity is dedicated to fiction versus real facts. I mean, I couldn't name all 50 U.S. states to save my life, but I could tell you the names of at least a couple hundred Pokemon without breaking a sweat.
Yeah, on second thought, maybe it's best I don't know the answer to that question...
