Walls

Merida, Jack, Rapunzel and Hiccup... All trapped by different kinds of 'walls'. When they receive a Hogwart's letter, they believe it's their ticket to leave behind the 'walls'. But things never happen as they're supposed to, do they? They may have escaped their trapped future, but have they really escaped their fate? Have they really escaped their 'walls? Rated T just in case.
