I loved the drop of Trixie's name. Even better that Dash said it
And yeah, now that I think about it, Featherweight was kind of a dick.
As for Dash, she's never really had too much interaction with the CMC, so there's no basis for loyalty. This is pretty much the first thing they've done to her and it's turned everypony in Cloudsdale against her. I'd be mad, too.
And if they had published something about DT, while I admit it would have been glorious, it wouldn't have accomplished what they needed it to. Unless they came out and said it plain and clear that they were sorry, it would have just gotten grouped in with the other gossip and nopony would care to read it anyway.
And Scootaloo can too fly! Didn't you see the back half of her suspended by her wings?
Now I get the image of somepony having a cutie mark that looks like their flank has just been shaved off and nopony believes it's a real cutie mark and so they shave it and then get confused.
