Here’s how I’d done it if it was as this:

Celestia: You did wha? And you did a Walking Dead scenario to prank Rainbow over your wounded pride, you few? And puppeteer others? And you also pose as Marere Do Well to oust Rainbow? Are you few out of your equine minds?
Pinkie Pie; Some say I am.
Dyscord: I know I can be. Flurtershy. Why did you help?
Flurtershy: I was relcutant. But I can zero say zero.
Dyscord; So you few exploit FLurtershy. As you exploit others. The accidents which happen were zero so. It was you few, zero doubt.
Celeztia: WHA? You humiliade a sibling figure and endanger many in the process. You risk the future of many out of arrogance, vanity, jealousy, doubt, prejurdice, and greed!
Twylight Sparkle: Come on….
Luna: I am familiar with many pranks in my day. But this one takes the cake.
(she chuckles)
Celestia: Seee here………. you brazenly reckless, irresponsible, hubristic, narcistic punks! You take your guilty accomplices and pawns; and apologise to Rainbow or you’d zero find your Cutie Marks. I’m an alicon. I can do it.

It also rock if there was something similar to The Incredibles only with EG Rainbow as Elastigirl and EG Twylight as Mr Incredible. Why? The Twylights tend to do rash errors without considering the consequences as many rememebr from Lesson Zero. And the Rainbows can be fiercely protectrive of their families. It especially rock to see Rainbow scoldign Twyligth for hypcorisy and say how it’s mroe than just about ehr.

It rock if we see one with JAne Porter scolding the ponies as well. And one with MAnny scolding. And one with Ellie scolding. And one with Hathi such as the 2016 or Netflix version scolding. And one with Aang scolding. And one with Kartara scolding>A nd oen with Ash Ketchum scolding. And one with Kari Kamiya scolding. And one with Sora scolding. And with the War Doctor soclding. And one with Optimus Primal in gorilla mode scolding. Their protective ferocity be why they’d be some zero might wanna anger.

I saaw the clip. And it tickle me the idea of Celestia saying those words to the ponies for betraying their sister figure.

I wish this did happen.
Celestia’s one you’d zero want to challenge.
