This art alone could say quite a bit about who Gilda is as a person. There's a lot of half-shadowing going on just from her posture and expression, and the fact that there's a happy picture of her and Rainbow Dash on her bedside table, where she can reach out and hold it, if she so wishes. Really wish people would use her more often as a character in stories, because there's a lot that can be expanded upon.
It's okay for FS to shout and insult/hurt her friends, but it's not okay for Gilda? Not even when she's being treated like shit by Pinkie Pie when she meets RD for the first time in a while? It's because Fluttershy's "adowable", isn't it?
Either way, the fact that Gilda hasn't reappeared yet, not even as an antagonist, screams wasted potential; my personal suggestion would be that she could be a sort of bad-girl-esque "I'm tough and act like I hate every one of you, but I'm lonely and love you guys to pieces" after some much needed character development. But hey, what do I know?
I love Gilda too, I honestly think she didn't do anything wrong: Yes, she acted like an idiot, but really, she hadn't met her best friend for a long time, and just wanted to hang out with her. I really hated the way the episode ended, she could come back in season 3...
I'm fine with gilda and i can understand her character a bit. as long as she doesn't make fluttershy cry I'm fine, but if she EVER is a jerk to her again I WILL PERSONALLY RIP OUT EVERY FEATHER ON HER BODY AND SEND HER FLYING OUT OF EQUESTRIA >:<
