2x1: The North Remembers
This season begins with Robb planning his next move in this war, looking for vengeance after the killing of his father. In the meantime, Tyrion returns to King's Landing to take his father's place as the Hand of the King, pissing Cersei and Joffrey off. Meanwhile, Stannis Baratheon decides to take a part in the struggle for the Iron Throne by the hand of his priestess, and the Night's Watch arrives to Craster's place.
The North Remembers is the first episode of Game of Thrones season 2. Back in King's Landing, Joffrey (Cersei's son) is the new king and Tyrion Lannister is the new Hand of the King as Tywin is absent.
The main conflict is who is the legitimate king. On one hand, Lannister family affirms Joffrey is the one because his father was Robert Baratheon. On the other, Stannis Baratheon claims the Iron Throne as hew know that Joffrey isn't Robert's son. Therefore, Stannis plans to attack and possess King's Landing.
Meanwhile, the situation beyond the Wall is critical as several white walkers have been seen and winter is really coming. Back in the Seven Kingdoms, Robb Stark holds Jaime Lannister prisoner and tries to use that levarage to recover his sisters.
