  The dragons featured in the episode's finale were implemented by BlueBolt, the lead VFX agency for the first season. VFX supervisor Angela Barson confirmed that the CGI dragons were among the most stressful effects, prompting sleepless nights. Commenting on the episode's climactic scene where the hatchling dragons are revealed, actress Emilia Clarke told VH1, "You see the relationship that Dany has with her eggs, and you see that grow and grow and grow and kind of the intuitive connection she has with them, you see that develop really beautifully". Clarke also hinted that she expected to "get to play with some more dragons!" in the second season, based on her conversations with book author and executive producer George R.R. Martin. "VFX Data Wrangler" Naill McEvoy later confirmed that dragon presence would be increasing in season two.
  In the scene where Joffrey forces Sansa to view the heads of Ned and his entourage on spikes, one of the prosthetic heads briefly seen in profile is that of former U.S. president George W. Bush. In their commentary on the DVD release of season 1, David Benioff and D.B. Weiss explained that this was not meant as a political statement, but rather because the production used the prosthetic heads that happened to be at hand. Following media reports in June 2012, HBO apologized for this shot, which their statement described as "unacceptable, disrespectful and in very bad taste". The statement also said that the shot would be edited for any future home video production and TV broadcasts. HBO removed the episode from digital download services until the scene was edited. In the edited scene, the head bears no resemblance to Bush.
