From Stack’s Tumblr:
““Eventually her twin closed its mouth as it met Twilight’s searing stare. Slowly it leaned in closer, its fear fading away as a smile spread across its face. Emulating Twilight’s stance it reared up and pressed its face against the mirror with a chuckle. Oh, are you angry because I told the uncomfortable truth about our friend? It hurts, giving voice to what you already know but don’t want to believe. It tilted its head as it regarded Twilight with amusement. Or is it something different? Something more… personal?”
