Do these count as plot holes maybe?
Why didn't Vanellope just tell Ralph that she is suppose to be the star of the game, that you play as and that King Candy took over the entire game and changed the Universe around? If she just would have told him that in the first place, than Ralph would not have gotten the wrong idea. She even allowed Ralph to destroy her car instead of telling him the truth, in an attempt to persuade him not to.
Also Felix is able to magically fix things right? So when Vanellope couldn't make it out of the game, since she is a glitch, why didn't Ralph just get Felix to fix her then, so she could make it out?
