When Rainbow Dash made a late night snack for herself, she was humming gaily to the candle-lit halls around her. When she took a shower, she felt like singing. When she sat on the stoop and looked out over the sleepy rooftops of Ponyville, she couldn't stop smiling.
An hour and a half later, she was fluttering into her bedroom. The container of pills sat lonesomely on the edge of her dresser, but she didn't even look at it. A pile of letters from her real estate agents sat in the corner of the room, but she paid them no heed.
She plunged into bed like a fifty pound explosive. The sheets flew up, then settled softly like snow around her petite body. Instantly, she curled up, snuggling into the darkness with only her quiet breaths to accompany her.
Lying there, gradually warmed by her own duvet, Rainbow Dash hugged her pillow, imagining it was a certain pony's soft embrace. She then ran a hoof through her bangs, envisioning somepony's phantom limb stroking through her mane instead.
"Never..." She murmured, smiling stupidly into the shadows. "We'll never have to be strangers." A stifled giggle. "You think I'm loyal to just anypony?"
A beat. Rainbow giggled, a very high-pitched thing that she could only afford when she knew that she was absolutely alone. The tone took a dive, and suddenly she was gasping harder and harder between each laugh. Then those gasps took prolonged, wheezing breaks, allowing bitter sobs to break their way through. Before Rainbow Dash could stop it, she was clutching her face, trying to lock the tears in.
"Idiot..." She hissed. "Stupid... stupid idiot. Of course it's nothing." She sucked her breath in and quivered. "It's always n-nothing..."
She didn't wail; she didn't moan. She simply twitched into the storm until it had passed over, and soon the veil of asleep absorbed her tears, as it did her breaths. Rainbow lay still as if in a grave, and blissfully passed the night away.
