The first season ends with tragic news reaching all corners of the Seven Kingdoms, which coincides with a shared vision by Bran and Rickon Stark. Meanwhile, Catelyn presses Jaime about her son's fall; Tyrion heads south following his father's surprising decision; Arya tries to escape from King's Landing; Jon faces a difficult choice at the Night's Watch; and Daenerys suffers a terrible setback.
Now, some rules that need to be followed.
If you have read the books, Do not tell people what's going to happen. At all. Don't tell people that a character is going to act differently in later seasons. Don't tell people that a character is even going to be alive. Don't tell people anything. Even if they're wrong about something, let them be wrong unless it involves something that's already happened on the show. Even if someone asks a direct question, remember that not everyone wants to know what's going to happen on the show.
By the same token, if you haven't read the books, Do not ask what's going to happen. There's a thread for discussing the books and the show. Ask there. All discussion in this thread should be about things that happened in the first two episodes of the series.
