[Scene cuts to several longships gliding through fog]

Stoick: I can almost smell them. They're close. Steady.

Stoick (cont.): Take us in.

Viking: Hard to port... for Helheim's gate.

[The boats disappear in the fog. A sudden jumpscare shows dragons attacking.]

[Scene cuts to the Arena, in the middle of a training session]

Hiccup: You know, Me And Jenny just happened to notice the book had nothing on Night Furies. Is there another book? Or a sequel? Maybe a little Night Fury pamphlet?

[A Nadder fires at him]

Hiccup: WHOA!

Gobber: Focus, Hiccup! You're not even trying!

Gobber (cont.): Today is all about ATTACK! Nadder's are quick and light on their feet! Your job is to be quicker and lighter!

Fishlegs: AAAAAH! I'm really beginning to question your teaching methods!

Gobber: Look for its blind spot. Every dragon has one. Find it, hide in it, and strike!

Ruffnut: Ugh! Do you ever bathe?

Tuffnut: If you don't like it, then just get your own blind spot!

Ruffnut: How about I give you one?!

[The Nadder attacks the twins]

Gobber: Blind spot, yes. Deaf spot? Not so much. Heh, heh, heh.

Hiccup: Hey, so how would one sneak up on a Night Fury?

Gobber: No one's ever met one and lived to tell the tale. [Snapping] NOW, GET IN THERE!

Hiccup: I know, I know, but hypothetically--

Astrid: [Whispering] Hiccup! Get down!

Damian: [Whispering} Please! Stay Low!

Snotlout: Watch out, babe. I'll take care of this. [tosses hammer at Nadder, but misses]

Astrid: Hey!

Snotlout: The sun was in my eyes, Astrid! What do you want me to do, block out the sun? I could do that, but I don't have time right now!

Damian: *Thoughts* What An Idiot.

Hiccup: They probably take the daytime off. You know, like a cat. Has anyone ever seen one napping?

Gobber: Hiccup!

[The walls start toppling as Astrid starts leaping from wall to wall, the Nadder behind her. Astrid jumps off the last collapsing wall, right onto Hiccup]

Astrid: HICCUP!

Tuffnut: Oooh! Love on the battlefield!

Ruffnut: She could do better.

Hiccup: Just... let me... why don't you...

[Astrid yanks the axe off Hiccup's shield and swings it at the Nadder]

Gobber: Well done, Astrid.

Astrid: [to Hiccup] Is this some kind of a joke to you?! Our parents' war is about to become ours! Figure out which side you're on.

Damian: I Know Which Side I'm On.
