Do not go hard on Twilight just yet, maybe season 4 will start with her crashing into wall or something, after all, you know what they saying:
Telling that everything is going to be fie is tempting fate, singing that everything is going to be fine is asking fate to strike you, so I am sure Twilight will find out in mid air that she got her wings 1 day ago and not yet know how to use them.
The whole series began as a "stupid marketing gimmick" You think they hired Faust just so they'd air a good series and nothing else? For Hasbro, it was always about selling toys. Have some faith in the writers.
