"So, Twilight, what did we learn?"
Pinkie Pie in a schoolmarm outfit smacking a ruler into the frog of her forehoof should not have been more intimidating than Chrysalis on the warpath. Operative word being "should." "Don't assume?" said Twilight, ears flat and wings ruffling, as though to remind herself that she was an adult princess and not waiting for Princess Celestia to come into the room so the teacher could tell her what Twilight had done.
Pinkie nodded. "Good. What else?"
"Listen to your friends when they voice their concerns?"
Another nod. "Uh huh. And?"
Twilight smirked. "And if they don't, know that it could lead to a wedding crashed by changelings."
The ruler came to a stop. Pinkie's mane broke free of the tight bun, though it wasn't clear if that was out of shock or just an inevitable product of the mane tie's finite tensile strength. "You... This was payback for Shining Armor and Cadence's wedding?"
Twilight shrugged her wings. "I mean, I didn't anticipate the changeling attack. I had a different plan ready to salvage everything once the brides realized how silly they were being. But honestly? Yes. Yes it was."
