Thanks to Gameloft's mobile game, we have new information on all three which could add to their characters.

Swoon Song: The only reason this pony hasn't asked Feather Bangs out yet is because she respects her friends too much to ask him first! ...She still really wants to, though.

(So she's willing to hold out for her friends rather than jump at the first chance she gets. How rare is it that a girl gives her close friends a chance to try and get with a guy she also likes?)

Dear Darling: This pony TRIED to talk to Feather Bangs this one time, but then she hyperventilated so much that she fainted. It was still worth it.

(Despite how much she swoons and fan girls over Feather Bangs, she herself gets nervous when she tries to talk to him. Imagine what Feather was feeling.)

Fond Feather: This pegasus has a secret collection of Feather Bangs fanfiction in her attic. The one where he defeats a bugbear with the power of song is particularly well-written!

(She writes fanfics about the pony she likes and has a collection of them in her attic.You could call her a stalker fan, but hey a girl's got to have her hobbies)

This information could make writing about them easier if you're not sure how else to portray them.

Swoon Song: Earth pony

Dear Darling: Unicorn

Fond Feather: Pegasus

At least with the latest mobile updates, we get a bit of an idea that they are more than just the standard trio of fangirls. Based on the description alone: In some way, we can imagine that deep beneath their good looks they are just as insecure as any woman. They'd each want to be able to talk to someone like Feather Bangs, but much like him something would prevent either woman from taking a chance. Whether it's loyalty among each other or nervous about leaving a good impression or they put their feelings in something other than talking like stories and such. They each have a flaw that prevents either of them from being the one to sweep Feather Bangs off his feet, just as Feather Bangs worries about being able to talk to one or all of them without looking like a blundering fool as most men on the show are portrayed as. In the end, I guess it all depends on one thing:

Who wants to be that one woman in the trio willing to be brave and take a chance, even if it may not work out? Better to try and fail than not try at all, as my father would usually say.
