Ask Angel Grace
"Of course. Did you ever see them again, Angel?"

“….I don’t think so…they all…rather look alike.” she shuddered.

"... What day was this one, Angel?"

“A few years ago…a bit before I got into Moon Worship…a couple of years before the Elements awoke…a day I prefer to forget…” Angel was still covering her face.

Fiddle is quite completely silent as she looks on. Her gaze scarcely wavers on watching these events unfold.

“No, no, I don’t think thats…” Angels protest and backing away came a bit too late as the guard nudged his companion.

“I…disagree.” the guard said meaningfully, pushing Angel to the ground. “Hold still and you’ll hardly feel a thing…” the two of them closed in on the younger Angel as she turned her head, covering her eyes with a hoof. A few moments later, the younger cried out, to be quickly muffled by one of the guards and dragged into the bushes.

Some time later, they returned to their post, and Angel Grace crawled out of bushes, leaving Canterlot.

"Ah. Well then... Shall we?" She gestures to the younger Angel.

Angel seems hesitant, but follows behind her younger self as she reaches the gates.

“I’m here to sign up for the guard!” she said cheerily. 

The front guard gives her a once over and snorts. “Go home. We don’t take your kind here.” he mutters, raising his eyes.

“…wh-what kind is that, sir?” she asked, her voice wavering. He prodded her with his lance roughly. “Street Vermin…likely stole those saddlebags…maybe I should give you a thorough inspection…”

"... So, what's happening today?"

“One of my greatest aspirations…my greatest, really. To be a guardpony. I figured, out from under my parents shadow, I could do anything I wanted. I was wrong…”

"I'm a pony without a cutie mark, and social boundries. We'll all broken here, Angel... And you need to know that. You need to know that it's fine to be broken. Because the cracks don't define you. The way the pattern interacts with the cracks is the important part. Look, lets... Fast forward a few years." Again, the scene dissolves, the transition little more than a breath.

At least the day was sunny this time. They were near the entrance to Canterlot, and nearby was a slightly older Angel Grace, scuffed and dirty but doing her best to hold her head high.

“…oh, not this day…” she whispered. “Can’t we go to when I met the Fiddler?”

A spark goes off in Fiddle's mind, "Ah! See that, there's the problem! You aren't a disappointment. You have talent... Power! You NEED to trust in that, or when the time comes... You'll fall. And that /can't/ happen."

Angel chuckles a bit. “I suppose so…but in the end, I’m still a pegasus who can’t fly. And what’s the point of that?”

"You never really talked to me about your childhood, Angel.."

“Understandably.” she said softly, as the voices continued to argue. Finally, it reached a cresendo:

“If she can’t be a weather pony, then what’s the point?!”

The younger Angel Grace stepped back, eyes widened, then she hung her head, tears dripping to the floor as she walked away, her body shaking

“And I’ve been disappointing ponies ever since.”

And there she was, creeping down the hall, "Well... I wish I had been given a script, then... If I had to guess, I'd say this is the day you stop being innocent..."

Angel followed close behind her. “…I never told you about this day?” she asked, as the filly stopped outside the open door, listening.

“…all her classes. She just isn’t cut out for flying, Thunder…”

A heavy thud, like someone slamming a hoof on a table, came from the room.

“She is a Pegasus and my daughter?! How can she not be a flier?” 

"Angel... Do you hear what you just said?"

Angel sighed, shaking her head. “Of course I do…running isn’t the same as not accepting.” Angel looked around for her younger self.
