Intertwined

Hiccup has been feeling odd, as if someone has been following him, but every time he turned around there was no one there for a cold breeze instead. Not only that, his dreams started to take a different route and in them there's someone he has never met before, but it oddly feels like he has, but that's impossible. After all, who in the world is Jack? HiJack/FrostCup, rated T.
