|“||When Hiccup is summoned to the Northern Markets to look into a curse that causes people to disappear, he is sucked down into a cavern of the fearsome Sandbuster.||”|
This section requires expansion.
- As of this episode, Hiccup and Astrid are betrothed, basically engaged to be married.
- Snotlout takes a jab at the show's name, asking who would like to race him to the Edge.
- The episode "Edge of Disaster, Part 1" is referenced by Snotlout when he reminds Hiccup about what happened last time they got a Terror Mail from Johann.
- This can also be a foreshadowing of Johann's true nature reveal in "Sins of the Past".
- It is mentioned that Astrid knows Hiccup better than Fishlegs.
- The Sandbuster in the episode is similar to the treasure-guarding dragons in the books How to Be a Pirate and How to Seize a Dragon's Jewel. Each dragon guards treasure underground. The Sandbuster is more like the Monster of the Amber Slavelands mentioned in How to Seize a Dragon's Jewel, because both dragons burrow underground, shoot glass, and drag victims into their burrows to rob/eat them.
- Tuff is said to have a trigger since childhood, where he breaks down and cries whenever he hears the word "tear". However, he has heard it and even said it multiple times in the past without becoming emotional about it-
- In "Breakneck Bog", Tuff says that Ruff slaps like a guy, and she slaps him to demonstrate. Tuff then says "I can't see through the tears."
- In "The Flight Stuff", Snotlout addresses the other Riders, including Tuff, when he thinks he's about to die, and says he doesn't want any tears.
- In "Dragon Eye of the Beholder, Part 2", Snotlout says within earshot of Tuff "Somewhere in the world a silent tear was just cried."
- In "Have Dragon Will Travel, Part 1", Ruff asks Fishlegs if Razorwhip eyeballs are dangerous, to which Fishlegs replies it has "poisonous tears". Tuff then excitedly exclaims "Poisonous! I love it!"
- In "Family on the Edge", Snotlout asks if Dagur is crying, to which Heather answers within Tuff's earshot "Yeah! Tears of laughter, at us."
- And in the later episode "No Dragon Left Behind", Tuff says "tears" again in reference to recognising real tears as opposed to fake ones when Astrid starts crying at the thought of Stormfly dying.
