I'm sure anyone who has read the books will notice that this episode marks the introduction(kinda, he appeared for a second last week) of Bronn, the hard as nails sellsword. One of the most popular characters from the series.
Incensed over news of Daenerys’ alliance with the Dothrakis, Robert orders a preemptive strike on the Targaryens that drives a wedge in his relationship with Ned. A captive Tyrion helps Catelyn, but receives a cold reception at the Eyrie from her sister, John Arryn’s widow Lysa (Kate Dickie). Sansa is charmed by the dashing Ser Loras Tyrell (Finn Jones), aka the Knight of Flowers. Arya overhears a plot against her father.
