The Berserkers are coming to sign a treaty, so Hiccup and the riders have to hide their dragons. Only problem is that the twins are having a huge fight, which means their dragon is out of control. Even worse is that instead of Oswald the Agreeable, his son Dagur the Deranged comes, bent on war.
Tropes
- Always Save the Girl: Stoick nearly kills Dagur to save the twins' dragons, saying that he is willing to risk war.
- Always Someone Better: Dagur stabs a table when a toast is called for his father.
- Bad "Bad Acting": Hiccup's performance is remarkably terrible as he pretends to "protect" Dagur from Toothless while whacking the latter with a shield.
- Bread, Eggs, Breaded Eggs: Taken to hilarious extremes when Tuffnut says he is out of the "Dragon business. And the sister business. And the dragon-sister business . .. 'drister' business."
- But for Me, It Was Tuesday: Dagur gives a laugh when he recalls drowning Hiccup as "good times".
- The Caligula: Dagur, and it shows when he gives himself the title of "Deranged."
- Call-Back: Dagur knows about how Hiccup lost his leg fighting the Red Death, and that he "trained" a dragon. Hiccup barely fends him off with Obfuscating Stupidity.
- This is also the first time the Red Death is referred to by its name.
- Chekhov's Skill: Fishlegs's hand signals come in super handy to fake a dragon attack.
- Deadly Euphemism: According to Dagur, Oswald has been "retired."
- Establishing Character Moment: Besides the horrifying tales we hear about Dagur, the very first thing he does onscreen is toss a knife at Hiccup.
- Evil Laugh: Dagur gives a long one when Hiccup recalls how the former would drown the latter while giving "swimming lessons".
- I Can Explain: Hiccup says this when Dagur nearly catches him trying to tame Barf and Belch.
- Just Eat Him: Tuffnut gives this as an order to his Zippleback head, to eat his sister.
- Mass "Oh, Crap!": Several times in the episode.
- Stoick, Gobber and Hiccup when they realize that Dagur instead of Oswald the Agreeable has come to sign with them.
- The Berkians when Barf and Belch storm into the mead hall, giving Dagur a dragon to hunt.
- All the teens except Hiccup, who gives a Death Glare, when Snotlout casually reveals that the Berserkers are going to behead Barf and Belch.
- Noodle Incident: Dagur seems to have many of them:
- He tried to behead Astrid during a fight.
- He locked Fishlegs in a cage for three days and fed him rotten fish heads.
- Hiccup recalls Dagur once nearly drowning him. Dagur laughs about it
