 Lord Tywin Lannister ( Charles Dance ) talks with his son Jaime ( Nikolaj Coster @-@ Waldau ) while the former is skinning a stag , symbolic animal of the house Baratheon . While Tywin chastises Jaime for causing the recent troubles with the Starks , he nevertheless believes this war is the perfect opportunity for the Lannisters to set up a dynasty as the new rulers of the Seven Kingdoms . Tywin gives half of his forces to Jaime to attack Riverrun , the seat of House Tully and Lady Catelyn 's childhood home , in retaliation for Catelyn 's seizure of Tyrion .
