Once an episode has aired on TV for the first time, there is a 7 day common courtesy cool down period or moratorium on spoilers and plot lines. After this period the episode can be freely discussed.

Big budget television shows usually première one a week, or every 7 seven days.
Even though Game of Thrones aired yesterday, remember the seven day rule, no spoilers!
