Flitter arrived back at the Cloudominium before Rainbow Dash. She huffed a bit, still irritated but she'd calmed down on the flight back, it wasn't Rainbow Dash's fault that people were drawing conclusions that annoyed her. On the assumption that Rainbow Dash wasn't spreading rumors but she had no reason to think that she was, besides the obvious fact that Flitter was a catch. Flitter snickered at herself, she was indeed, though her living with Cloudy and some... Untoward rumors that started had bit that in the flank for a bit until she and Cloudy had done some yelling at certain ponies for spreading such rumors. Flitter rolled her eyes in annoyance at those memories, goodness it was amazing what some people would gossip about wasn't it?
Flitter looked up as Rainbow Dash walked in, good, they needed to talk. Rainbow Dash beat her to the punch. "Oh hey Flitter, I thought you'd be with Cloud Chaser."
Like a shot, Flitter was on Rainbow Dash. Looking back Rainbow Dash couldn't tell you exactly how Flitter had managed to knock her over so quickly. Flitter looked down at Rainbow Dash from standing on top of her. "What happened!?"
Rainbow Dash took a few moments to collect her senses after that tumble, shaking her head and managing to stop herself from snapping at the other pony, Flitter was worried about her sister and Rainbow Dash admitted that perhaps she could have phrased that better. "Nothing Flitter! I just thought you were going to visit her!"
Flitter blushed gently and her ears lowered in embarrassment, climbing off of Rainbow Dash and sheepishly helping her to her feet. "O-Oh... Yeah... Sorry about that." Flitter quickly turned away and started to trot towards the stairs.
"Oh no you don't! I deserve an explanation after that!" Rainbow Dash was usually a live and let live kind of pony, but after being tackled like that she felt she was owed an explanation for such an overreaction. She would admit her own partial fault in the issue but it was still an overreaction.
Flitter flinched and took a few more steps as if contemplating still trying to escape before sighing and turning around, walking back to Rainbow Dash, her wings still folded at her sides but obviously very stiff, Rainbow Dash could see the irritation almost dripping from Flitter and was about to call the demand off before Flitter spoke. "One question."
Rainbow Dash blinked and shook her head. "Uh... No that's ok Flitter you don't need t..."
Flitter interrupted her with a low growl. "One question." Rainbow Dash frowned a bit, was this some... Quid-pro-quo thing with Flitter? She felt the need to repay Rainbow Dash for having jumped on her, she shrugged, she supposed that arguing more would just make it more awkward, and asking some lame question would probably just piss her off.
"Well... Okay... Hey, what was that bit about Chaser getting a new room but no sadness?" Rainbow Dash saw Flitter flinch again, trying to think up another question quickly enough to change it but Flitter was already explaining.
"Well when we were kids our parents weren't... Particularly close." At Rainbow Dash's raised eyebrow she sighed. "Two younger ponies doing what's fun rather than what's prudent." Rainbow Dash nodded after a moment. "But when we, me and Cloudy, came along father did what was socially expected of him and married our mother." She gave a half shrug. "Though they didn't share a room they got along well enough, and we were a fairly happy family as far as it went."
Rainbow Dash nodded, though she wasn't sure what this had to do with anything. "Sure, sure, but then what..."
Flitter groaned loudly and glared at Rainbow Dash who wasn't sure what she was missing that would make Flitter so annoyed at her. "They didn't share a room, me and Cloudy did. When our mother... Didn't come back from the hospital..."
Rainbow Dash's eyes widened and she nodded. "Oh, oh, I see. Yeah... Sorry about the question." Flitter shrugged and turned to go back upstairs before freezing as apparently, Rainbow Dash didn't know when to leave well enough alone. "But you know they said Cloudy's gonna be fine, full recovery and all that."
Flitter turned her head back around to glare at the offending pegasus. "That's what they said about mom!" She whirled on Rainbow Dash, advancing on her. Rainbow Dash seeing the angry flitter bearing down on her hastily backed up. She was stronger and slightly larger than Flitter but she wasn't about to try and face off against that ball of pure anger. "And what if they're wrong again!? I lost my mother! And now I'm going to lose my sister too! What else is this world going to take from me!?" Rainbow Dash opened her mouth and no words came out. "Next my daycare will burn down, my kids will become sick, and for all I know Equestria will be overrun by changelings! What could you possibly say to comfort me in this moment Rainbow Dash!?"
Rainbow Dash, wisely, chose that silence was her best answer, snapping her mouth shut and simply standing there looking at the other mare. Flitter, seemingly satisfied with this choice of hers whirled back around and charged up the stairs to her room. No, not her room, a room she borrowed from Rainbow Dash because of her overprotective, suffocating sister who couldn't accept that Flitter was a grown mare insisted she be here, instead of in her own home with all of her good memories to comfort her, she had to be in this strange place! A door of clouds couldn't really be slammed, but the whoomph of air as it moved quickly through was satisfying enough to Flitter.
Rainbow Dash simply stared after the other pony, her eyes boggling slightly after Flitter just unloaded a cart full of emotional baggage onto Rainbow Dash. She thought to herself for a moment, trying to think of the best way to deal with this before nodding. She knew how to deal with this! Or at least she thought maybe she did? At least this was how she dealt with Fluttershy when she exploded the very, very few times she had bottled up her emotions up enough to cause her to throw a fit, as much a fit as Fluttershy could at least. Rainbow Dash dashed out of the Cloudominium and down to Sugar Cube corner to buy a fancy croissant and dashed over to Rose Luck's house to ask her for a favor, before returning home with said croissant and a dozen roses from Rose Luck. Bring her gifts and then give her a hug, that was how to cure Fluttershy, it should work on Flitter too.
