Details are starting to emerge about season 6 of Game of Thrones, and it's appears the show will solve the problem of moving faster than George R.R. Martin can finish a book, by going back in time to look at the history of the Stark family.  This will also involve telling the story of how Hodor became Hodor and why he only says...."Hodor".  Along with this, is the exciting news that both Ian McShane and Richard E. Grant are joining the cast!
