Race To The Edge: Shell Shocked Part 2

In this episode, Hiccup and Astrid share their third kiss as a couple!

Viggo is aware of Hiccup and Astrid's relationship, and taunts him with it, telling him how odd it is that he is in love with a girl who is his partner in battle, which winds Hiccup up, but he forces himself to concentrate on the task at hand, to stop Ryker.

After defeating Ryker, Hiccup goes to check on Fishlegs. After Fishlegs leaves, Viggo lands on Stormfly holding Astrid captive with her own axe to her throat and states that he will release her in return for the Dragon Eye, asking Hiccup if he is going to sacrifice his future for it. Hiccup throws the Dragon Eye into the volcano, which makes Viggo let go of Astrid and run to it, thus showing that Hiccup will do whatever it takes to protect Astrid.

At the end of the episode, just prior to the explosion of the volcano on the Edge, Hiccup, and Astrid end up kissing after promising to keep their relationship out of the war with Viggo, and their kiss is seen by the other Riders, erasing Ruff and Tuff's suspicions about an 'illness'. Snotlout, on the other hand, seems to be convinced of a gambling problem.
