A/N: I've seen so many of these fics, so I decided to write my own. I'm actually not neutral on the subject of who is better than who, but I've tried my best to portray both of them accurately. This will have three chapters, so hang on! Discalimer: I don't who Doctor Who.
Chapter One: The Rose's First Meeting
River looked around, she and the Doctor had gotten separated by some aliens. The impossible man had charged off into their command center on their mothership... Alone. River had run after him, but in her distraction she'd failed to notice the teleport.
So now, she was stuck on Earth with no vortex manipulator, this being one of her days where she relented and left her vortex manipulator inside the TARDIS... Maybe because the TARDIS was a little jealous that she insisted on carrying the thing around for emergencies.
River heard a noise, as if someone had teleported and a bright flash of light came from the alleyway she'd just been down. River unhooked her gun from her belt. A few shuffling noises, a cough, and River whipped around the corner aiming her gun. To her surprise a blond haired girl with full lips and a slim body reacted immediately pulling out a black gun also.
River arched an eyebrow as the girl frowned in puzzlement. Something about this was... Familiar.

Rose hadn't excepted to find a gun pointed at her face as soon as she'd jumped from the previous parallel universe. Rose frowned. The woman who was currently pointing a gun at her was mature with wild curly blond hair and a full hour glass figure. Unlike her own leather jacket and jeans, the woman was wearing a wide leather belt and a white jacket.
Strangely the woman suddenly cocked her head and smirked.
"Rose Tyler, isn't it?"

River Song's eyes lit in recognition. Oh! She'd seen this girl before, in fact she'd been in this girl's room, and maybe she'd forced the Doctor to confront his feelings, like any good wife would- he'd been bottling it up for ages, it really had done him a world of good to get it all out.
"Rose Tyler, isn't it?"
Rose, she was sure of it now, shifted warily, "Do I know you?"
River placed her gun in her belt, "No." River wrinkled her nose, "Something's off about you... Oh, you've been dimension jumping, haven't you?"
Rose nodded dumbly, "How did you know?"
River smirked again, "Spoilers."
Rose clutched her gun tighter. This woman wasn't reassuring at all. Something was wrong with her, she felt off and dangerous. Very dangerous, even though she wasn't holding her gun anymore.
"Spoilers?"
"Your name precedes you, Bad Wolf."
That was unsettling. Rose decided to take a line out of almost every telly show or book she'd ever read, saying, "You seem to have me at a disadvantage, you know me, but I don't know you."
Rose regretted it, something mischievous sparked in the woman's eyes before she said, "River Song, the woman who killed the Doctor."
In an instant Rose's gun was back up and pointed at her. Rose's eyes widened as she realized that the woman was laughing.
"I'm sorry, couldn't resist!"
Rose's eyes flashed a golden yellow, and River calmed, but her eyes still shone with barely concealed mirth.
"Tell me, now, why did you say that?"
"Why, don't you think that's quite fast, demanding my life story? We haven't even gotten past the introduction."
Rose glared and River's eyes narrowed, "No need to be demanding, Bad Wolf."
"I haven't said anything yet."
River shook her head, "No, but you won't shut up."
"What?"
"Time Lady dear, do keep up."
Rose almost dropped her gun, "There are other Time Lords?"
River relaxed the tension leaving her body, "Not quite. No, I won't explain anymore, no, I can't answer anymore of your questions... Well, I might answer one..."
Rose still gripped her gun, but she spoke, "What is your relation to the Doctor?"
River sighed, "That one will take all week and I'm on a bit of a tight schedule. I killed the Doctor, but I didn't. My parents were his companions- but none of that is possible because, well, he doesn't exist... oh, and he's my husband."
Rose blinked, "What?!"
"Oh my, its time for you to go. One more thing, I apologize for my behavior! I was a bit jealous, younger me, you know- what can you do? To be frank it was my first time meeting one of you that came before, and well, I was a bit more of a psychopath back then. Sorry."
"What?!"
River reached out and pressed the dimension hopper on Rose, who yelped and reached out to bat away her hand just a moment to late. She vanished with a fizz leaving River alone in the alley.
River brushed away an errant curl and turned to leave. A flash came from behind her and River turned to see the Doctor standing there fiddling with his sonic and glancing at the sky at the departing spaceship, "River, where on earth have you been?"
River flashed him a grin, "Just catching up with a friend of friend, Sweetie."
"Friend of a friend?"
"Oh, girl stuff come on."
She pressed a kiss to his cheek and sauntered off leaving a puzzled Doctor to sniff the air in a strange familiarity before shaking his head (because no, that was impossible) and following his wife into the streets of London.
