Prompt: 'last night was a haze for both of us and somehow we woke up hungover in a bed that isn't either of ours and also neither of us recognize this apartment we should probably get out of here before someone calls the cops on us' au

Blake was awoken by a thin beam of sunlight, falling through the blinds to pierce her head like a lance. She groaned at the pounding in her sensitive ears and attempted to pull the blankets up over her head. They barely budged, though the movement was enough to dislodge several empty bottles that had been strewn across her.

Looking to her left, Blake discovered the reason why. She was not, in fact, alone in the bed. A slender girl with black hair highlighted by red was curled against her side, and drooling gently onto her shirt. The mystery girl's brow creased at Blake's shifting, and she let out a long, pathetic groan.

"Mmfgnhead." She mumbled, and Blake nodded in sympathy. After a moment's groggy thought, the girl whipped her head up to look at Blake with a startled bwuh?!

"Hey." Blake's mouth felt like it was stuffed with cotton. "I'm Blake, in case you can't remember my name either."

"MmRuby. Nicet'meeyou, Blage."

"Nice to meet you too, Ruby." Blake sat up gingerly, looking about the room while she massaged her aching temples. Then she noticed the other girl in bed with them.

"Holy shit."

Ruby rolled with another groan to follow Blake's gaze, then gasped.

"Blake, is that Weiss Schnee?"

"That is absolutely Weiss fucking Schnee. We absolutely probably had some kind of sex with Weiss fucking Schnee."

"And I can't remember it? How is that fair?!"

"Fate plays cruel games with us all." Blake shifted to slide out of the bed as silently as possible. "I don't feel like talking to any lawyers, though, so I think I'm going to clean up and get out of here before she wakes up. Do you mind if I use your bathroom, Ruby?"

"My bathroom? I thought this was your place."

Blake froze. This did not look like a Weiss fucking Schnee kind of apartment. It definitely wasn't her own – for one thing, it was nicer than hers – and if it wasn't Ruby's…

"Ruby? Whose apartment is this?"

"I… don't know?"

Perfect. As if the debilitating hangover wasn't bad enough, she had apparently also boned a perfect stranger and the heiress to a multi-billion dollar dust mining and refinement corporation – in someone else's apartment.

"Okay Ruby, I would really like to not go to jail, so we should probably get out of here ASAP. Can you…" She couldn't believe she was even saying this. "Can you try to wake her up?"

"Wake her up?! She'd kill me! Or sue me! I don't know which is worse!"

"I know, but we can't just leave her drunk and unconscious in a stranger's house, can we?"

Ruby looked conflicted, but in the end her conscience won out. "Fine, fine."

Blake ducked into the bathroom, splashed some cold water on her face, checked herself over in the mirror, and headed back into the bedroom.

"So…" Ruby looked worried. "She's not waking up."

"What?!"

"Don't get mad at me! When I tried to wake her up she just bit my hand and rolled over!"

And that was how Blake found herself lugging a dozing heiress around an apartment building she'd never seen before in her life, while Ruby checked ahead to make sure the coast was clear. Not, perhaps, her most dignified morning, but at least she was in good company. She'd have to remember to get Ruby's number, once they figured out what to do with an unconscious girl worth more than they'd make in ten lifetimes.
