Fast forward a couple weeks to the bunker after everyone has made it through the rift

Lexi pulls the heavy bunker door open and the sound of the small crowd below reaches her ears. Sam had text her an hour earlier to let her know they'd made it out, they had Mary, Jack, and a few others, and everyone was okay. She'd only been home from London a few hours, still hadn't even unpacked her bag, when the text came through.

The dark-haired girl approaches the railing slowly and looks down at the small crowd of 25 to 30 people mingling in the war room. She quickly spots the youngest Winchester standing over in the corner talking with a red-headed woman who's sitting in a chair.

She makes a beeline for him down the stairs and gives a small smile to the older bearded gentleman who looks at her slightly shocked, but he smiles back.

A warm smile crosses the taller brother's face as Lexi quickly makes her way over to him and immediately hugs him tightly.

"Aww," the Scottish accent from the red-head surprises Lexi, "You didn't tell me you had a girlfriend Samuel."

"Rowena," Sam begins introductions, "This is Lexi and she's just a friend."

"That's a shame," the red-head replies with frown, "Nice to meet you regardless."

"Same," Lexi replies with a smile, realizing this is Crowley's mother the boys had told her about before.

"Hey stranger," Mary says with a smile as she approaches, and Lexi nearly knocks her backwards as she rushes the woman quickly and wraps her arms around her.

"I'm so glad you're okay," the dark-haired girl replies once she pulls away from the woman.

"Me too," the mother states.

The older gentleman approaches and Mary turns to him with a smile, "Bobby, I want you to meet Lexi, she's…family."

The blonde gives Lexi a warm smile as she rubs her back with one hand in a motherly fashion.

"That doesn't surprise me," Bobby replies and Lexi notices the sadness in his eyes.

"Nice to meet you," Lexi says offering him her hand to shake.

Dean makes his way past his mother and reaches his hand towards Lexi, "Hey you, come on."

"Okay," she takes his hand cautiously and follows him toward the library.

The older brother sees Ketch raise one eyebrow curiously at him as Dean makes his way past him into the library with Lexi in tow. Once he reaches the far side of the library, he turns and pulls the girl to his chest, holding her tightly for a moment.

"Dean," she says quietly as he releases his grip, "What's going on?"

"You should sit," he replies.

Normally she would be defiant, but she does as he asks and takes a seat in the chair closest to her. She was racking her brain trying to figure out if this was bad news. Most of the people she cares about are in the other room, so why the solemn face?

"If this is bad news," she begins as he pulls a chair up in front of her and sits down, "Can't it wait? Can't we have a few hours of happy for a change?"

"No," he shakes his head and a small smile crosses his face, "This isn't bad news Lex, it's just…you know how we told you Apocalypse world is a universe where Sam and I were never born."

"Right, alternate timeline," she replies.

In the other room, Bobby looks over to where Rowena and Charlie stand talking.

"Everything okay?" Mary questions her friend.

"Your Lexi," he begins with a small smile, "Spitting image of our Lexi. She and Charlie were thick as thieves, until a year ago when Michael killed her."

"Oh, I'm sorry," the blonde-haired woman says sympathetically as she glances into the library where she can see Dean and Lexi talking.

"Everyone from our world exists in that world, they just might not be the same," Dean continues with a smirk, "Bobby's pretty damn close to our Bobby though."

Lexi's face breaks into a smile, "Did you find alternate universe me? I mean, I'm not saying two of me would be awesome, but come on, it wouldn't not be awesome."

Dean laughs a little, "No, we didn't find another you, but we did bring back someone we both know."

Realization starts to sink in and Lexi begins to shake her head slowly, "Are you saying she's here?"

"She doesn't know us."

Lexi stands quickly, and Dean does the same, grabbing her arm to stop her from moving past him, "I want you to be prepared, she doesn't know you like you know her."

Sam notices the red-head start to make her way toward the library steps and he quickly chases after her, trying to stop her.

"Charlie, wait," he calls out, but she's already up the steps.

He watches as she stops, staring at the two people across the room, and he moves to stand beside her quietly.

Lexi grasps the arm which is holding her wrist to keep from falling, her knees went weak as soon as the other girl came into view. Her red hair was longer, and she didn't have on a classic nerd t-shirt, but she looked the same. Charlie and Lexi stood across from each other staring in bewilderment, their eyes brimming with tears.

The red-head finally moves closer to the other girl, Sam following behind her. Dean could feel Lexi's grip tighten on his arm as Charlie stopped a few feet in front of her.

"Lexi?" the name came out as more of a question, than an acknowledgement, causing the brothers to change curious glances.

A single tear escapes as the dark-eyed girl gives a single nod.

Charlie pulls Lexi away from Dean's side and into her arms. The dark-haired girl clings to the red-head and Sam gives his brother a small smile. The older brother smiles back, after all, he and Sam had shared that same embrace many times when they thought they'd lost each other or might lose each other.

"I'm sorry," Charlie says as she releases the other girl, "You look just like my Lexi."

"Trust me," Lexi replies, wiping at her eyes, "I understand."

"You had a Lexi over there?" Sam questions trying to clarify.

Charlie nods her head, "She was my best friend."

"Same," the dark-haired girl says, "Our Charlie was like a sister to me."

The red-head playfully punches Lexi's shoulder, "Come on, have a drink with me."
