Sarah said, "Toothless, you better come up here until later."

Toothless went up there and the vikings knew that it could only mean trouble

Stoick:
Hiccup!

Hiccup:
STOP!

Stoick:
SON!

Hiccup:
DAD! NO!
[Stoick jumps in front of Hiccup and takes the shot, being killed instantly]

The vikings gasped and Astrid held Hiccup back and Stoick sat there in shock

Hiccup:
Dad!

Valka:
Stoick...

Hiccup:
No... you...
[Valka checks for a heartbeat]

Hiccup:
No
[The Bewilderbeast turns away and stops controling Toothless. His eyes widen once more as he comes to his senses, realizing in horror what he's done]

Hiccup was upset and had to calm down so, Astrid kept hold on Hiccup.

Hiccup:
No, no, no. No...
[Toothless sees Hiccup grieving and goes to Stoick's body]

Hiccup:
No! Get away from him! GO ON! GET OUT OF HERE! GET AWAY!

The Berkians weren't at the same time they were shocked at his tone

Valka:
It's not his fault. You Know that.
[The Alpha takes control over the dragon's again. All their pupils shrink into slits as the Alpha takes command of their will]

Valka:
Good dragons under the control of bad people...
[As the Alpha roars, the viking teens' dragons are controlled as well. They fly away toward the Alpha]

Snotlout:
Wait, don't go!

Valka:
...do bad things

The vikings sat there shocked and wondering what Hiccup was going to do
