Ahem
Dear Princess Celestia. Sometimes, when a pony, or a group of ponies, comes face-to-face with a problem, they can tend to get distracted by the situation at hoof and the issues its causing them. Sometimes it can distract them so badly that they might not notice that the solution has been right in front of their faces all along. Sometimes all it takes is an outside view from a friend to put everything into perspective and whip those ponies minds intoahemshape.
Your faithful student,
Twilight Sparkle.
P.S.: Lets stay away from the overarching storylines for now. Answering questions is more fun!
