Game Of Thrones: 10 Worst Things The Starks Have Ever Done

10. Catelyn Captured Tyrion

Ever since the sack of King's Landing, when Ned walked into the throne room to find Jaime sitting atop the Iron Throne, there has been bad blood and tension between the Lannisters and the Starks. Things weren't helped years later when someone tried to open Bran's throat while the Lannisters were guests in Winterfell.

After Littlefinger revealed that the blade the cat's paw used to attack Bran belonged to Tyrion Lannister, and Lysa claimed the Lannisters murdered Jon Arryn, Catelyn convinced Ned to travel south and find out the truth.

On her own travels, she just so happened to cross paths with the Imp, and seized the opportunity to capture him with or without hard evidence of his accused crimes. This had quite the ripple effect throughout Westeros, reaching south in King's Landing, and to the Lannisters in the west.

Every Lannister is fiercely proud, and the kidnapping of Tyrion was seen as an insult to their House. Jaime's typical hot headed reaction was to confront Ned in the streets of the capital, killing Jory Cassel and injuring Ned in the process. In the west, despite his resentment and hatred toward his youngest son, Lord Tywin raised his banners in preparation for war with the Starks.

This, and the fact that Tyrion was actually innocent, eventually leaving the Eyrie unscathed, plants this act as one of the Starks' biggest mistakes.
