Good thing they waited until the S8 premiere to bring her back instead of doing it in the S7 finale and having it feel like it's too soon.
Also, please don't let this be another "Starlight saves the Mane 6" plot. As much as I love Starlight, I would rather see her work WITH the Mane 6 to defeat a villain. Plus, if they keep having the Mane 6 get kidnapped offscreen and be damsels in distress, they won't feel like main characters anymore.
