The cold winds are rising, but Stannis Baratheon may be a more pressing problem for the Lanisters in 'Game of Thrones.' In the latest teaser for Season 2, King Robert's brother stakes his claim to the throne currently occupied by young Joffrey.

"My brother left no true-born heirs. By right and birth and blood I do this day lay claim to the iron throne of Westeros. ... The iron throne is mine by right." He follows this with the chilling threat: "They will bend the knee or I will destroy them."
