Summary
“No one else is allowed to have you, Riley,” Agatha growls, crawling through the dirt. “Only I’m allowed to have you.”
Rio ducks a strike from the blunt end of Agatha’s knife, aimed at her temple. She protests, “if you love me, why are you trying to kill me?”
“It’s how I show affection!” Agatha shrieks. Rio pauses for a second, crouched in the dirt; she’s got a point. They do tend to get a lot of their mushy feelings out by throwing each other into trees and making each other bleed.
or: rio accidentally stumbles into wanda's hex and agatha's periphery. a jaunt through various television plots occurs. my contribution for AAA week.

Summary
"It's been amazing to meet you, Professor! I honestly can't believe I get to work with you."
She has a lovely smile, more genuine than most would be able to manage at the start of the year. . Lorna likes that in a student.
"It's been a pleasure. I look forward to seeing what you're capable of."
The young woman beams again before turning to go, casually waving goodbye. Her jacket- not quite appropriate for the sunny day- slips off her shoulder as she does.
Underneath her sleeve, peeking out at her like a waving flag, is a very distinctive birthmark.

In 1986, rising musician Lorna Wu makes the most painful decision of her life. In 2010 (long after her retirement from the performance circuit) that decision comes back to haunt her.
Then again, smiling at her from the front row of her composition class isn't exactly haunting behavior.
And it's fine, it's really fine. She'd been preparing to see her daughter again for over twenty years, she can handle it.
Now her daughter's incredibly attractive adoptive mother, on the other hand...

Summary
“Who the fuck boards up their windows and doors?”
Rio stared at Agatha with incredulity, as though it was the stupidest question she could have possibly asked.
“I don’t like visitors.” Rio shrugged. Agatha’s eyes nearly popped out of her skull. “Most visitors, I guess” She added, raising an eyebrow in Agatha’s direction. The academic felt a faint blush dust her features at the look.
“Christ, get a sign like a normal person.”
Or:
Agatha is a 28 year old PhD student travelling Italy to gather research for her thesis. What she didn’t count on was being caught breaking and entering by a 500 year old vampire, Rio Vidal.

Summary
Rio Vidal hasn’t bitten a living person in almost a century - not even when the hunger scraped her ribs raw.
No, she follows her rules, the ones she carved into herself - and she never breaks them. Not ever.
Until one night, after neglecting her hunger for almost a week, she gets sloppy sneaking into Westview Memorial's Blood Bank and a dark-haired, really beautiful nurse puts her hand in front of her food.

Summary
There is a new cosmic-level threat to the universe.
A lethal assassin operating under the moniker ‘Lady Death’ has single-handedly desecrated entire planets, erased multiple species, and brought empires to their knees.
Lords tremble at the whisper of her name. Worlds quake at her arrival. Many have tried to kill her, but she doesn’t bleed as one would, she doesn’t die as she should.
For all intents and purposes, she is Death, reincarnate.
But there is some hope— an old-wives tale that her soulmate, and only her soulmate, can harm her, can kill her once and for all.
And the hunt for that very person just drew blood.
Which is how FBI rookie Agatha Harkness finds herself on the front lines of a war that threatens to tear apart the universe. With the entire fate of her world resting on her shoulders, she must go toe-to-toe with the most feared woman in the entire cosmos.
No biggie.

Summary
“It’s nice,” she nods, taking a second piece before she begins to suck the juice off of her fingers, inserting each one individually into her mouth and releasing them with an audible pop that nearly sends Rio into a coma. Thank God, it’s too dark for Agatha to see the blush on her cheeks, thank God she can’t hear the ferocity with which Rio’s heart is desperately trying to break out of her ribcage.
