I must admit it: she’s the smartest villain MLP ever had.

I’m aware. Her whole redemption/reforming is still bullshit, though, and future seasons like this just help illustrate that much.

Starlight chose to change. Cozy… did not.
 
Yeah, true, but that always felt forced as hell, considering she went from “Let the world be destroyed if that’s what it takes to get my revenge!” to “Woe is me, I’m scared of trying to make new friendships!” in the same of a commercial break.
 
I’m actually genuinely surprised they didn’t end up doing something like that with Cozy, considering the track record.

At least Starlight wanted to change and even helped Twilight fix the timeline. This little devil here didn’t even care about her ‘friends’ and even sent the mane 6 to Tartarus. And if we are going complain about Starlight redemption, let’s also complain about Luna redemption, Tempest Shadow redemption, Sunset Shimmer redemption (yes, she wasn’t really punished for trying to kill Twilight and friends with that fireball. Unless you call helping the school a big punishment for trying to conquer Equestria and kill someone). All these characters unlike Cozy Glow showed that they could change and wanted to change. Who knows, maybe Cozy will change someday. We still got season 9.

Yeah, I’m kind of getting Infinite Crisis ending vibes from this.

Plan A is a success, now on to Plan B
 
I have so many question right now, did she purpose stealing the Equestria magic just to get into Tarturus to meet face to face with Tirek. If she did, her plan is working and is entering phase 2 of her plan.
