What is there more to say?
Pinkie is Pinkie.
But is it really that farfatch'd?
To know there can be such a thing as Battlesaurs?
No one knows.

What do you think?

SPIKE HAS TO SAVE HIS BIG BROTHER THAT HE NEVER EVER KNEW EXISTED BEFORE ITS ALL TOO LATE! THIS IS A RACE AGAINST TIME TO THE DRAGON LANDS FOR ONE YOUNG DRAGON TO SAVE HIS AILING BROTHER AND...

Oh? Did I mention that said big bro is Garble, the guy that tried to kill him, of all dragons?

And that said rescue is pretty much just a slice of compassion of a cute little dragon raised by ponies to a grieving teenager?

Yep, Shattered Scales gives Garble and his pals some dignity to their characters.
Takes place two weeks after the episode that these bad dudes have first appeared in.
