So I suppose you can say…
What Cook's doing is wrong, she knows its wrong, but she's gonna do it anyway.

Remember, intentionally bad is still bad, because of this lampshading rarely works, but if you want to see it done the right way, watch Dave the Barbarian or Billy and Mandy.

Another possibility:
1. Cook wanted to do an alternate Mane 6 storyline.
2. She was prevented from doing this for some reason.
3. In interviews, she has stated that certain storylines are prohibited because they conflict with or are too similar to something planned in a future episode.
Conclusion: Alternate Mane 6 in season 5.
