"The last clip was of toothless and hiccup flying above a cloud. Hiccup is upset about something as he lets out a yell of annoyance before falling back in the saddle so he’s lying on toothless. A few moments later we see a mask come up out of the cloud to the side of toothless and Hiccup says, “Oh come on Dad…” Then stops as he sees that it actually the mysterious dragon rider. Who then glides back below the cloud. Hiccup sits up and grabs the reins saying,”don’t worry buddy”. Then another massive dragon (two or three times bigger than toothless) erupts from the cloud in front of them, making toothless and hiccup brake fast. The mysterious dragon rider is stood on the neck of this dragon. As hiccup and toothless are looking at this new rider another dragon comes and picks hiccup off the back of toothless’s back, making him fall down into he ocean below. Toothless is frantically trying trying to get out of water but he can’t as he can’t fly out on his own. As he is trying to get out of the water there is a group of manta ray(not normal ones. These have massive spikes in their spines) that are heading towards toothless. As they reach him they swim past him and drag him underwater.
The scene changed and went to where hiccup was being carried by the dragon. He’s shouting at them to stop as his dragon can’t fly and he’s being ignored. As they reach the mysterious dragon riders base he is dropped and he rolls on the floor before springing up and turning to face the nearest dragon which is behind him. He draws his fire sword and switches it on so the flaming and begins to wave it in a pattern before reaching out to touch the dragon on the nose. Next he steps back, changes some sort of canister on the sword and flicks it on the ground in a circle around himself. This activates green smoke before he flicks the sword again and that smoke becomes flames. Hiccup turns to face the mysterious rider and begins to ask him to go back to get toothless and the mysterious rider taps his stave on the ground which is a signal to another dragon to fly over and drop toothless next to hiccup. Hiccup hugs toothless and toothless begins growling at the mysterious rider who has started to move towards the two of them. The rider has his hand outstretched towards toothless and the he twists his wrist and toothless falls to one side."
