Talk:Twilight's Kingdom - Part 2/@comment-26973802-20140407030701/@comment-24542482-20140408120429

I would say the best case scenario is the library is what becomes crystalized. Basically, just as Twilight gained wings, but it has not been a plot device of any episodes since, it may be that in the end the library will change, so that season 5 will remain unaffected. Also, it is best, because whether the episode is bad or good, it will not affect the quality of future episodes..

Essentially, the episode may be a device to sell new merchandise.
