A couple typos I noticed:
On page 16, "that grants adventurer's their crest" should be "that grants adventurers their crest".
On page 19, "she's can get by" should be "she can get by".
Jade is such a well-renowned hero, upstanding citizen, and a wholesome guy all around, that he gets to hang out with little girls all the time and nobody dares question the purity of his intentions. If this was any other series, he would've been called a lolicon at least once.
My headcanon is that Jade's crush on Garnet has been common knowledge for years, and Garnet was basically the last person in town to realize.
A dragon becoming an adventurer. That's something else, for sure. I kind of doubt she will have much use for the flower crest, though. She's a dragon and will get more powerful than most human adventurers simply by growing up.
Yeah, but dragons probably grow up much slower than humans, so she'll be stuck in a child's body for a while. Essentially, being a dragon naturally gives her a high level cap, but having a crest will let her level faster than normal.
