Having watched "Magical Mystery Cure", I can see it going in the following:
- I think that they're trying to play up the "with great power comes great responsibility" arc
- At first, Twilight is first excited at becoming a princess, but does she really want to be one?
- What would happen to her friends? Will she value her friends more than being a princess?
According to Meghan McCarthy, "Magical Mystery Cure" is part 1 of 3.
