We're now 3-4 episodes into season 4 and the writers have yet to define what role Princess Twilight Sparkle will play in Equestria. Now to be fair it is still early days, but the titles of the next four episodes do little to inspire confidence that they will define Twilight's role early on in the season. I feel that the writers should inject something small about Twilight's ascension, just enough to push it along. This would avoid cramming it into a single episode. In many ways this season has two season long story arcs. The keys and Twilight herself.
