  ===Writing===
  Series veteran Bryan Cogman wrote the episode, his first of two episodes of the season.
  "Blood of My Blood" was written by Bryan Cogman. Cogman has been a writer for the series since its beginning, previously writing seven other episodes, as well as the subsequent episode. The title of the episode, "Blood of My Blood", is a reference to the famous Dothraki saying between a Khal and his bloodriders.
  In an interview with ''Entertainment Weekly'', Cogman described some of the thought process he had when writing the reunion between Samwell and his family, saying, "As much as Sam has gone through, I love exploring those family dynamics. His mother and sister and brother are all fundamentally decent people but his father is just a cold hearted bastard when it comes to his distant son. There's a painful part of the scene where his father just unloads on him and tells him every hateful thing he ever thought about him and Sam can't defend himself. We found that fascinating – Sam has killed a man, he's killed a White Walker, he's emerged as such a great hero, but he still can't stand up to his dad."
  Cogman noted, about the Arya storyline in the same interview, that he comes from a theater background, and that "being able to comment on the show and the reactions to the show through the players were so much fun. The show is often accused of being gratuitous in all kinds of way – the violence and the bigness of the characters. It's a huge operatic story. We're able to lovingly spoof ourselves but also play with ideas about how audiences view the show, good and bad, and how a perspective of a story changes. Plus there’s the dramatic deliciousness of Arya watching her own life play out on stage." Weiss also spoke about Arya, saying "We were excited to do the play within the play, and it's a distorted fun house mirror representation of things we've already seen." Benioff continued, "Part of Arya's amusement is just that she knows that they're getting so many details wrong, but she always regretted that she didn't have a chance to watch Joffrey die, and now she gets to. It's obviously a comic version of it, but that gives her great pleasure." Weiss also noted, "Arya is slowly getting seduced by these performances, and Lady Crane, the actress that she's charged with killing, this is somebody who like her has taken as her life's work the job of becoming other people."
  In regards to the final scene of the episode with Daenerys Targaryen riding Drogon and emboldening her newly acquired khalasar, Benioff stated in the "Inside the Episode" featurette that the scene is a reflection of the speech that Khal Drogo gave before his death, with Benioff saying "One of our favorite moments from season one was watching Khal Drogo deliver a speech to his gathered khalasar, that speech clearly lingered in Daenerys's mind, and she's echoing almost the exact same language when she's talking to the Dothraki now. She's basically telling them the promise that one of the great Khals had made years before and saying now is the time to live up to that promise and fulfill it."
