"It's about you."
Rarity frowned, confused. "Me? Did I do something wrong?" Then her expression turned to worry. "Is something plotting against me?"
Twilight gave a nervous look behind herself, at the ponies trotting outside the shop window. "It's more complicated than that."
Catching her intention, Rarity flipped the sign hanging from the door, and lowered the blinds. "Tell me."
Twilight cleared her throat, moving to sit on the nearest chair. "It's about the other you," she explained. "The one in the human world."
"Oh, goodness." Rarity moved to sit in front of Twilight. "Did something happen to her? Is she alright?"
Twilight looked hesitant, and took a moment to swallow before continuing. "She's safe, right now, if that's what you mean. No accidents or serious physical harm. Not yet at least." She paused for a second, breathing in. "But she's not alright. And I need your help. She needs your help."
Rarity leaned a little closer to Twilight. "I will do what I can, Twilight, that's not even a question. But will you please tell me what is the matter with her?"
Twilight looked to the side. "You know that cupboard you keep under lock and key, the one where you store wine bottles and occasionally take one out for special occasions?"
Rarity nodded. "I take it my human self shares my fine tastes in drinks."
"She unfortunately doesn't share your moderation," Twilight replied. "Not as of late, at least."
Rarity pursed her lips. "I know I went too far myself a few times when I was younger. A rather disgraceful display. And with such unrefined liquor, too." She shook herself out of her reminiscing. "But that is not the topic here. I believe what you're saying is that something has pushed her to drink? And how bad are things, currently?"
Twilight chose to answer the second question first. "I only know what Sunset has told me, and she only knows what her and the others have been able to piece together. But as far as certainties go, from what their Sweetie Belle has said, she spent a whole late afternoon and evening drinking, to the point where she passed out still dressed on top of her bed at the end of it, without having dinner. As far as what else she might have done..." Twilight looked to the side again.
"Yes?"
"Well, you don't know what a car is, but... Imagine a cart, but faster, and made of metal. And imagine a bunch of those being driven around, and it's all like the traffic in Manehattan," Twilight explained. "Now imagine doing that while drunk." Before Rarity had a chance to freak out, she continued, "They're not actually sure she did it. Just that the keys were moved at some point. But in her current state, she might have."
Rarity put a hoof to her forehead, frowning in worry as she looked down. "You want me to talk to her, right?"
"The others don't know where to start. You know yourself better than anyone else." Twilight offered her a tentative smile.
"And why is she like this?" Rarity asked, again.
Twilight wanted to look away again, but forced herself not to. "There are things about the other Rarity you don't know. And there's a reason I haven't told you or others about them." She sighed. "This isn't only about you."
