Shining Armor is concerned; his sister Princess Twilight left for the Minotaur's homeland, far to the west of Equestria, over a month ago, but nopony has heard from her or her escorts since. Princess Cadance told him not to worry, but he can't help but feel that something has gone horribly wrong. Finally, he can't take it any more and sets out to find out what happened to his younger sibling.

Surely he's worrying about nothing, right?
