Summary
“We got engaged?”
Rio looks at her, puzzled. Her eyes dart back and forth between Agatha’s.
“You remember?” Rio asks carefully.
Holy shit. She’s engaged to Rio.
She’s engaged to Rio.
Her heart feels like it’s about to give out and that burning in her ribs feels like fire.
When did this happen?
“Not really but I guess it makes sense.” She’s barely able to hear the words leave her mouth over the beating of her own heart.
“So you remember Wanda?” Rio asks dejectedly. Agatha frowns, confused all over again.
“Wanda?” She repeats. “Who’s Wanda?”
—————————
Agatha wakes up in hospital with amnesia after a car accident and immediately jumps to the very logical but extremely wrong conclusion about her best friend. As she tries to piece together her life with memories of Rio and no one else, she’s forced to ask herself an important question: Why did she agree to marry the wrong person?

Summary
"What's your name, Hon?"
"Ri-" She stops. If this is someone close enough to leave fliers in her friends bar regularly, it's someone who might know her name. It's not exactly common. "River."
"Bullshit." The voice on the other end sounds amused. Rio can hear the smile in it.
"Well Jolene isn't your real name either, is it?" Rio fires back.
"Baby, I'm doing sex work. I need the name to protect my identity, but you don't have to hide from me."
"I could say the same to you."
"With all due respect, I didn't call you up for phone-sex did I?"
Touché.
Rio is absolutely furious when her girlfriend tells her she's breaking things off, partially due to the fact she's too quiet in bed. Hoping to get comfortable with dirty talk, she takes her friend's advice to call up a sex hotline to practice on a stranger.
It takes her far too long to realise that the woman she's having casual phone-sex with is none other than her best friend of ten years.

Summary
“Uh, hi.” Rio fingers the strap on one of her backpacks. “I’m- meeting someone here? Actually, I’m… moving in. Well, I’m not moving in, but I’m staying- um, do you know Ag-”
“She’s with me,” a sharp voice says, and- oh. Agatha Harkness exits the rightmost elevator. She’s dressed in tailored black slacks and a blousy white top, dark hair loose over her shoulders, falling in waves that are unfortunately just the right size and shape for Rio to reach up and tug. Her heels clack against the marble tile floor.
“Hi, Agatha.”
“Rio Vidal.” Agatha gives Rio a onceover – no less thorough or scrutinizing than her flashy doorman – and turns away quickly. “Hi, Clint. She’s the one I mentioned before. Do you have her key ready?”
or: broke grad student and certified lesbian disaster rio vidal crashes on agatha harkness' foldout couch. it's a lot more life-affirming than you'd think.

Summary
Friday nights have belonged to Agatha and Rio for years.
Dinner, bad documentaries, shared blankets, and a spare key neither of them remembers making permanent. Their friendship has quietly expanded into every corner of their lives, but neither has been willing to ask whether it might already be something more.
Then Rio mentions that someone asked her on a date.
Agatha reacts with all the grace and emotional maturity one might expect, which is to say, not at all.
A week of jealousy, one badly handled argument, and several years of mutual pining later, they are finally forced to admit that the friendship they were both so afraid of losing may have been love all along.
