Background
Theon is the youngest son of Lord Balon and Lady Alannys Greyjoy. Balon is the head of House Greyjoy and Lord of the Iron Islands. The Iron Islands are one of the constituent regions of the Seven Kingdoms and House Greyjoy is one of the Great Houses of the realm.

Theon was born at Pyke. He is Balon and Alannys's fourth child after Rodrik, Maron and Yara. Eight years before the start of the series Balon rose in rebellion against the Iron Throne. The ironborn were crushed in a war led by King Robert Baratheon and Lord Eddard Stark. Theon's brothers were both killed in the fighting. Balon surrendered and was allowed to remain Lord of the Iron Islands on the condition that Theon remain a hostage and ward of Eddard Stark. Theon's sister Yara has remained on the Iron Islands. Despite his status as a hostage at Winterfell, Theon has been treated well by the Starks. He and Robb Stark are best friends. Theon is a skilled archer.

Theon suggests killing the pups, but Jon Snow convinces his father that this is an omen as there are five pups and five Stark children, Eddard consents to allowing his children to adopt the pups. Just as the party leaves, Jon finds a sixth pup, an albino, the runt of the litter. Theon ruefully points out that this one belongs to Jon.

He reacts angrily to a further insult from his favourite prostitute, Ros, after sneaking her into the castle to engage her services.

Theon and Robb exchanges views over the matter of Jory Cassel's death and the growing Stark-Lannister animosity in King's Landing. Robb brusquely reminds Theon that he is not a Stark.

Reaching the Twins, Theon shoots down several ravens leaving the castle bearing messages from Lord Walder Frey, allowing Catelyn to negotiate an alliance. Theon fights alongside Robb at the Battle of the Whispering Wood, where Jaime Lannister is taken prisoner. When Robb laments the loss of 2,000 of his men in the feint at the Battle of the Green Fork, Theon assures him that songs will be sung of their bravery. Robb responds that they will not hear them.

 * Main: Theon Greyjoy Season 2

Theon appeals to Robb to seek an alliance with his father, Balon Greyjoy, reasoning that Robb needs a fleet to attack King's Landing. Robb sends Theon home to Pyke as his envoy. Theon is deflated at the lack of a reception for his return. His sister Yara poses as a stranger to see what Theon has grown up to be. He flirts with her relentlessly. Balon greets Theon coolly, believing that he has forgotten his roots and become loyal to the Starks in his time away. Yara reveals her deception and Balon compares Theon to his sister unfavourably. Balon rejects the alliance Theon suggests and is insulted that Theon thought he would accept being given a crown. He reminds Theon that they pay the iron price and take what they want.

Balon reveals that he plans to attack the North while it is poorly defended. Balon gives Yara a fleet of thirty ships to take Deepwood Motte and insults Theon by assigning him a single vessel to raid fishing villages on the Stony Shore.

Having decided to betray House Stark he is baptised in the name of the Drowned God as Balon and Yara watch. He takes command of the Sea Bitch but finds his crew unruly.
