Mewtwo should have ignored her.

He should've left the half-dead Eevee on the slopes of Mt. Silver; left her to be claimed by the frigid weather like so many other trainers and Pokémon who had perished over the years.

To be honest, he'd barely noticed her at all, due to the fact her silvery-white fur blended in with her surroundings.

It was the eyes that had caught his attention.

Two red pools among the ocean of white.

He knelt by her and touched her lightly. The eyes moved, looking at him before closing. Mewtwo felt her pulse quicken slightly, but nowhere near a pace he'd consider normal.

And so he had used his power to erect an igloo around the Eevee and begun the task of saving the child's life.

After drying her, she twitched, then shivered violently, which pleased her rescuer. He carefully held her close, letting the heat from his own body seep into her, checking her pulse to make sure she didn't go into cardiac arrest.

Her body temperature was still dangerously low and he didn't any warm liquid to give her...well...he did, but he didn't have the means to give it to her reliably.

Shaking his head, Mewtwo pushed the thought to the back of his mind. While liquid was out, there was warm air he could give her...

Pinching her nose shut, he gently breathed into her mouth. After a few minutes, she stirred and coughed, shivers running up and down her body.

"Come back to me, little one," he murmured. "There's still so much for you to do."

Once she'd stabilized, he picked her up and teleported to his current home, deep within one of the many cities scattered around the world. Standing in the center of the living room, he wrapped the Eevee in blankets and went to pour her a drink.

When he came back with a glass, her eyes were open. Mewtwo met her gaze and smiled slightly.

"Welcome back," he said. Her ears twitched and she frowned before shaking her head, wincing. He stepped closer and she went still, watching him warily. "I mean you no harm."

Her eyes narrowed then moved to the drink in his hand. A small pink tongue wet her lips and she nodded slowly. Mewtwo gently placed the glass to her lips and she drank slowly, relaxing as she did so. She blinked drowsily and yawned.

Mewtwo checked her pulse and was pleased to find it strong and healthy. He unwrapped the Eevee and she stretched carefully, letting out a small hiss as she flexed her paws.

"Thank you," she said, looking up at him, tail wagging slowly. "My name is Sasha."

"Mewtwo."

She tilted her head. "That doesn't really sound...well...normal."

Mewtwo arched a brow and crossed his arms. "It's rare that I meet a Pokémon who gives themselves a name as well, Sasha. It's a nice name.”

She flicked her ears and looked away. "Right, well, thanks for patching me up. I'll just be going then."

She didn't make it three steps before she collapsed with a snarl of pain. Mewtwo winced and gently picked her up in his telekinesis, laying her back down.

"You really need to be checked at a Pokémon Center," he said. "The only reason I didn't take you there straight away is because I'm trying to avoid any unnecessary attention."

She glared at him. "You're a psychic. Teleport me."

Mewtwo narrowed his eyes thoughtfully before shaking his head. "There's regulations against that for several reasons."

Sasha sighed and rubbed her face with a paw. "So I'm stuck here until you're satisfied that I won't keel over?"

Mewtwo nodded.

"Fine," Sasha grumbled. "But as soon as I'm able, I'm gone."

"Come on."

"No."

"It's not nearly as bad as you think it is."

"Do I look like a human to you?"

"...Okay, fair enough, but you're roughly human-shaped and therefore eligible for wearing a suit."

"I don't have a problem with wearing suits. Just the tie."

"You're a psychic."

"And tying a tie is beyond me. I'm not ashamed to admit it."

"What about a bow tie? Clip-on?"

"Why not add a fez and call it a cosplay while you're at it?"

"Oh for..."

Sasha shook her head at the stubborn clone. "Looking nice for a date isn't going to kill you."

"It's not a date," Mewtwo replied stiffly.

"It's just the two of you having a nice quiet meal together and depending on how things go, maybe a different kind of dessert at the end of it all," Sasha said innocently.

"You've been reading way too much fanfiction," Mewtwo snorted.

"You're the one who didn't clear their browser history," Sasha replied.

Mewtwo glared at her before sighing and looked at himself in the mirror.

"You don't have to wear the suit if you don't want to," Sasha said gently. "What matters most is that you're comfortable."

She ran a critical eye over his body and shrugged. "You were designed to be a fighting machine with the capacity to survive in any environment. Looks came second to that."

"Thank you, I've read my own file," Mewtwo replied dryly.

"Just making sure you know not to dwell on whether or not you're worthy of her attention. And if she does make advances, not to think too hard of what she's attracted to you for."

"My charming personality, I'm sure," Mewtwo snarked.

"Get going," Sasha chided him, making a shooing motion with her paws. "And if you bring her back here, try to keep it down, would you?"

Mewtwo telekinetically smacked the troublesome Eevee as he left the apartment. Sasha chuckled softly and gazed around the cozy four-room apartment before turning to the bookshelf and picking one at random to pass the time.

The two unlikely roommates stared at one another. 

One had an amused smirk on their face while the other wore one of embarrassment. 

"What do I owe you to not breathe a word of this to anyone?"

Sasha arched an eyebrow mischievously. "I'm an Eevee. I don't have much that I want or need."

As Mewtwo's shoulders slumped, she leaped up onto the bathroom sink and glanced at the mirror. 

"Wouldn't it be easier to practice kissing a pillow or something? A mirror can't exactly mimic a mouth's movements."

Mewtwo turned on the tab, wet his hand and swiped the mirror clean, using Sasha's tail to dry off. "Because if I practiced on a pillow, you'd tease me even more about it. It was my fault for leaving the door open."

"I know she looks like you and has a similar origin to yours...so if you two actually get together, would that count as-?"

"Finish that thought and you can spend the rest of the week as a Magikarp."

"Why don't you ever bring your dates home?" Sasha asked Mewtwo as the two binged through a marathon of fantasy films.

"Because trying to woo a member of the fairer sex isn't easy when there's someone providing running commentary," Mewtwo replied.

"I only did that once!"

"And once was enough to know that if I ever wanted intimacy, I'd have to do it far away from you."

"You think I'm going to forget the time you practiced kissing on me?"

"I'm more curious as to where you picked up that talent."

"I'm good at a great many things from my years spent wandering Kanto and Johto. Whereas you, my genetically engineered friend, are still woefully unprepared for the next step in your relationship with Rei."

Mewtwo fidgeted uncomfortably and averted his eyes. "We'll cross that bridge when we come to it."

"Speaking of Rei, do you have a pet name for her yet?"

The clone hesitated before nodding. Sasha gazed at him expectantly before giggling.

"Oh come on, Mewbutt, it can't be that bad."

"It's silly," he muttered. Sasha snorted.

"Silly nicknames are quite common in relationships."

Mewtwo sighed and rubbed a hand over his face. "Dove. I usually call her Dove."

"That's adorable; didn't know you had it in you. Congratulations," Sasha replied warmly.

"Thanks, Sasha."

He was silent for a moment before he spoke up. "And what of you? Anyone who's managed to catch your attention?"

Sasha's mouth thinned and she shook her head. "After having my innards fried by a Flamethrower, I haven't really been interested in romance. I usually prefer a good book or a feline body pillow to lay on rather than anything intimate or romantic."

Mewtwo gazed at her silently before his hand touched her back. "You're stiff as a board," he chided, picking her up and transferring her to his lap as his fingers worked expertly over her spine.

Sasha's irritated growls swiftly because pleased purrs and incoherent mumbling as the psychic clone undid the knots in her muscles.

Mewtwo tsked over the state of her fur and began to brush her as well. "You need to take care of yourself," he murmured, carefully untangling her fur. "Some day, I'm sure you'll find someone who cares for you, even if you can't..." 

Sasha's claws dug into his leg and Mewtwo gently rubbed her back.

"Very well, I'll not pester you about it."

"Thank you."

"You're brooding again."

Mewtwo jerked slightly at the sound of his roommate's voice. Without turning, he answered.

"I have a lot to brood on."

He felt the brush of fur against his leg before Sasha leaped up to balance precariously on the railing that circled the roof of the apartment building.

Mewtwo finally glanced at her and flinched under her disapproving stare.

"What?" he asked defensively. "Don't you ever think back on your life and wish you could've done things differently?"

"You know the answer to that," Sasha said coldly. Mewtwo winced and looked down at the busy city below.

He felt Sasha relax and her warm cheek rubbed against his arm that was braced against the railing as she sighed quietly.

"You've never been able to settle down in one place for long because of who and what you are. That much I can understand...after Red demolished Team Rocket in the Sevii Islands, I went to Johto and got tangled up in that mess. Then you managed to pry me off Mt. Silver and here we are, months later, not going anywhere. Why's that? Are you afraid of leaving me behind? Or taking me with you?"

"I wouldn't be able to guarantee your safety-"

Sasha's loud snort caught him off guard and he met her red-eyed glare with a blank one of his own.

"I've read the horror stories that surround other Eevee. And since I'm an alternate color, it's even worse since breeders would use me for a chance of producing more. Being with you is the safest I've been in years."

Mewtwo was silent, tail twitching slowly before he stood back. "Fair enough," he said reluctantly. "I haven't heard any rumors about us around town so we don't have to leave yet. But if the opportunity ever comes up, is there any place you'd like to go?"

"Probably somewhere tropical. Alola or Hoenn," Sasha replied, tail flicking about as she balanced on the thin rail. "Although Hoenn tends to have radical weather shifts, what with being home to the weather trio and Castform."

Mewtwo made a face.

"And we won't be staying in some musty cave," Sasha added. "Probably a coastal town with an inn with a nice view of the setting sun so you can brood more."

"Alright, I get it," Mewtwo grumbled, swatting the Eevee lightly with his telekinesis. His eyes went wide in horror as Sasha tipped over the railing with a startled yelp and with a thought, he latched onto her aura and teleported her to him. Catching the Eevee in his arms, he fretfully stroked her.

"Stupid, stupid, stupid, I completely forgot...are you alright?"

Sasha's heartbeat slowly resumed something resembling normalcy as she took a few deep breaths to calm herself.

"Well, once the initial shock wore off and shelving the thought of my rapidly-approaching death, it wasn't really scary. I can see why flying-types are so carefree."

Listening to Mewtwo's pounding heart, Sasha frowned. "Hey," she said, gently headbutting him to get his full attention.

"I almost lost you," Mewtwo murmured. "Stupid, impulsive...I thought I'd learned to control that."

"It was my fault for pushing you," she said gently. "I'm sorry."

Mewtwo sighed and stepped further back from the edge, cradling the Eevee against his chest, stroking over the soft bundle of fur.

Sasha's ears warmed and she hid her face against his chest. "Idiot," she mumbled, more to herself. Mewtwo glanced down at her before taking her back inside.
