A great episode for teaching us about how we easily forget our values, how we see seek our worth in others and how everyone we know struggles like us.
The part with the shame naming can be tiny bit morally confusing but it emphasize the idea on how we have a delusional perspective on how we see our self's and others that is connected with our troubled pass.
The name being 'Rainbow Crash' is a good name for RD to remember her time becoming one of the Wonder Bolts and the lessons she learned, the change of idea toward the name shaming to be a reference about on how we changed from a struggle they faced to become a WonderBolt , and how to appreciate to be a part of something awesome.
Trying to be awesome for others is not awesome at all!!
The cherry on top is how we learn that the Wonder Bolts aren't perfect coolest team that RD used to think of them, but hard and dedicated members that struggled like Rainbow Dash at the end.
The Idea of Rainbow Dash trying to place her name is interesting because she confronts her fear that she not might be as great as every other pony in Ponyville thinks of her.
This idea was used in a couple of episodes before but is a great metaphor (for example) on how family's opinion's about us are always great but people outside won't see that personal side and greatness of you at first.
Overall one of the best episodes in Season 6!
