(Ta-da! There was ONE pony you didn't mention in that line-up who's cyan-colored hair appears onscreen, not that she wanted a 'girls' day' if that meant what she thought it meant.

Didn't mean she wouldn't go hang out, but she'd probably fall asleep mid-way through the planned events.)

Rarity!! Hehe, guess I'm not the only pony who showed up before Hearth's Warming Eve.

(A beat, and she blinks.) ...Wait a second, you were here with both Twilight and Fluttershy?!
