  The episode was written by series co-creators David Benioff and D. B. Weiss.
  The episode was written by producers David Benioff and D. B. Weiss, based on the original work of George R. R. Martin. "The Prince of Winterfell" adapts the content of chapters Arya IX, Tyrion XII, Theon V (48, 55 and 57) from ''A Clash of Kings'', and also parts Jaime I and Catelyn I (2 and 3) from ''A Storm of Swords''.
  Among the added material there are the relationship between Talisa and Robb (which in the books happen offscreen and in an entirely different context) and the Qarth plot (which is still only loosely based on the books). Other changes include Arya using her third "death" to flee Harrenhal instead of contributing to the fall of the castle to Bolton's Northmen, revealing the hidden cache of “dragonglass” found after Jon's departure, and having the wildlings capture Qhorin Halfhand alive.
