Bolton proposes sending his bastard son with the forces left at his stronghold, the Dreadfort, and Robb reluctantly agrees, demanding Theon be taken alive so he can personally execute him.

The website's critical consensus reads, "Thanks to a balance of thrilling action, complex character work, and a savage twist, 'The Old Gods and The New' justifies its deviation from the source material.
"[13] IGN's Matt Fowler gave the episode a perfect 10 out of 10, noting that "Book purists will certainly have their gripes, but I found 'The Old Gods and the New' to be nothing short of an intense triumph; (sic) filled with tons of cruelty and shock.
She also praised the thematic unity of the episode, achieved by making the large number of character arcs take place in the course of a single day.
[15] Jace Lacob of Televisionary echoed the above sentiments, calling the episode by far the best of the season thus far: "All in all, 'The Old Gods and New' represented a massive achievement for Game of Thrones, a stunning display of well-crafted dialogue, subtle acting, deliberate pacing, and glorious setting, and the firm establishment that the show's continuity is well and truly separate from that of the novels."
