The setup for Episode 4, as per Telltale (warning, spoilers for episodes one through three):

In Episode 4, the fate of the scattered Forresters hangs in the balance, and no one allied with the family is safe. An unexpected meeting offers Rodrik a new opportunity to free Ironrath from its Whitehill stranglehold, but with young Ryon Forrester still held prisoner, his next moves are critical.

Gared must abandon Castle Black and venture beyond the Wall in search of the mysterious North Grove, risking encounters with Wildlings and worse. In King's Landing, the population is reeling from a recent royal death, and Mira must step carefully in an increasingly complex game of politics where secrets are traded as currency.

Far away in Essos, Asher infiltrates the slave city of Meereen at the behest of Daenerys Targaryen, but will the friendship he holds dear break under the strain of a mission that raises memories best forgotten?
