A/N (Edit): I posted this after being up all day on very little sleep so I forgot to add this author's note thanking the people who reviewed. Please Please Please review! When I don't get reviews I feel like nobody really liked what they read, and if nobody likes it, why continue it? You'll also get updates faster if there are more reviews because if I know people are reading it and excited about it, it motivates me to write.

San Francisco, Ca.

2001 Hours

Outside of an Office Building

Stiles and Lydia looked up and saw a small drone hovering over them.

"What do you think that is?" Stiles wondered aloud.

Before Lydia had time to answer, a small opening appeared at the bottom on the drone.

"You don't think that's going to start shooting bullets or lasers or anything, right?" Stiles asked anxiously.

A blue light shone from the opening and traveled from their heads to their feet then back up again.

"Lydia Martin." The drone, who was apparently a female, spoke. The front doors to the office building unlocked. "Please, come inside."

"Thank you." Lydia said with confusion, but walked toward the doors. Stiles followed, but was stopped before he could enter by a jolt of electricity. He flew backwards and landed on the ground in front of the building.

"Oh my God! Stiles!" Lydia ran back to Stiles, who had landed on his back, and knelt down next to him.

"He is not in my database." The drone spoke.

"He's with me." Lydia told it.

"He is not in my database." The drone said again.

"I'm not going in without him!" Lydia said sternly.

"Very well." The drone did not seem happy-if drones could have emotions. It printed a badge with "Visitor" written on it. Stiles's face from when the drone scanned them was pictured right above the word.

Lydia stood and grabbed the printed badge from the drone and turned back to Stiles. "Are you okay?"

"I'll be fine." He croaked out. Lydia helped him up and he leaned on her momentarily while she helped him inside the building.

"I'm fine." Stiles told Lydia again once they were inside. He sounded weak, and Lydia gave him a look that said she didn't believe him, but let him go anyway. The lobby of the office building was dark and empty. Suddenly an elevator door opened up.

"Going up," Came from the elevator, spoken by the same robotic female voice that the drone had.

Stiles and Lydia exchanged looks and she grabbed onto his arm as they walked toward the opened doors.

"Floor 15 as usual?" The voice asked.

"Yes." Lydia replied after a moment's hesitation.

The doors closed and the elevator shot up to the 15th floor. Once the elevator stopped and the doors opened again, the two of them stepped out into a dark hallway. There was only one door and it was controlled by biometrics. More specifically, a hand print.

"Well, the robot lady seems to know who you are." Stiles said with a shrug when he and Lydia shared a confused look. Lydia bit her lip and laid her left hand on the glass. Access Granted in green text appeared on the screen with Martin, Lydia in white text right underneath and a picture of Lydia right next to it. "Whoa! That's you, but you look…different." Stiles told her. Her hair in the picture was pulled back, probably into a bun, and she was wearing glasses.

The door in front of them unlocked and they entered the room. "Lydia?!" They heard from somewhere in the large room. "Is that yo-" A girl appeared around the corner, but stopped short when she saw them. She was in her late teens/early twenties with mocha skin, bright blue eyes, and straight brown hair. "Oh my God!" She spoke with a British accent.

"Do I know you?" Lydia asked her. Something about her seemed familiar but at the same time she knew for a fact she had never seen this girl before in her life.

"Yeah, well, I mean…no, but…not yet… I…I need to sit down."

She disappeared behind the wall she had just come from and Stiles and Lydia exchanged looks, then followed her. There were several computers set up around the room. This was definitely a lab of sorts. She sat down in a rolling chair then motioned to a few other chairs in the room. "Please, have a seat. I have so many questions."

"You and us both." Stiles quipped as he took a seat across from the girl.

"You're Stiles." It was a statement, like she was realizing it. Stiles froze and exchanged looks once more with Lydia.

"Yeah. So that makes you…?"

"Elbie."

"Elbie," Lydia started slowly, "What are we doing here?"

"And where exactly is 'here'?" Stiles added.

"And when exactly is 'here'?" Lydia finished.

"Okay, slow down." Elbie said, throwing her hands up. "The when and where is easy. You're in San Francisco in the year 2043. April 3rd to be exact. The 'why'… well…that's a little more difficult, because frankly, I have no idea. What year are you from?" Elbie asked the two teens.

"2016." Lydia answered.

"Wicked." She smiled and leaned forward.

"How do you know Lydia?" Stiles asked the girl.

Elbie didn't answer right away. She seemed to be contemplating how much she should tell the two of them. "She's my roommate and we work together."

"Where am I?" Lydia asked. "I mean, the me of this time."

"I...I don't know." Elbie told her. Stiles and Lydia each gave her questioning glares and she quickly stood up. "I don't know what I can and can't tell you. If I say the wrong thing I could change the future." Then she mumbled, "God, knows there's enough of that going on right now."

"What's that supposed to mean?" Stiles stood slowly, and raised his eyebrow.

"I shouldn't have said that." Elbie told him with wide eyes.

"Okay," Lydia said, standing up. "Look, I get it. We're dealing with the very fragile nature of time, so just do us all a favor and get us back to our time and we'll forget all this ever happened."

Elbie looked shocked for a moment. "How did you know that?"

Lydia looked back and forth from Stiles to Elbie. "How did I know what?"

"That you wouldn't remember anything when you make it bac-" Elbie noticed the confused looks on both Lydia and Stiles's faces. "You didn't. You were just saying... okay, see I'm really bad at this."

"Okay, let's start over." Stiles tried. "Just get us back to the nemeton and then maybe-"

"Wait!"Elbie said suddenly. "You came through the nemeton?" Stiles and Lydia nodded. Elbie sighed and plopped back down in her chair. "The nemeton was meant to be a beacon to call Lydia back here. But you came instead of her which means..."

"I don't like that look." Stiles pointed at Elbie, but looked at Lydia as he said it.

"What the hell." Elbie shrugged. "Like you said, you're not going to remember any of this," Stiles and Lydia looked at each other with confusion, but Elbie missed the look completely and continued "And I don't see another choice." She stood quickly. "Sit down." Stiles and Lydia both sat back in their chairs. Elbie took a deep breath and began. "About 17 years ago, Lydia met a man."

"Oh?" Stiles asked with a raised eyebrow. Lydia glared at him.

"Not like that." Elbie clarified with a hint of sadness in her voice. "You see, a lot of bad things happened to your pack. Some of it you've seen already and some of it is still to come. This man claimed that he was responsible for all of it...Something about the pack ruining his life...He wanted to make you all suffer. He was from our future and he had gone back in time and changed the past. The man told Lydia that she was the one who invented time travel in the first place an-"

"Seriously?" Stiles seemed proud.

"It's all physics." Lydia told him. "I'm sure if I put my mind to it, I could figure it out."

"You did." Elbie told her. "Anyway, he died trying to kill you, Lydia. And you...well she set to work. Her plan all along was to figure out what he changed and fix it. I didn't start working with her until about five years ago-"

"When you were thirteen?!" Stile's asked in shock.

"Fifteen." Elbie corrected him. "At that point, she had figured out the basics. She made a few trips and that's how we learned that you wouldn't remember anything once you were back in your own time. She studied and researched and finally figured out what needed to change in order to set everything straight again and she made a list."

"I'm sorry." Stiles raised his hand as if he were in a classroom. "Why couldn't she just make sure the guy was never born?"

Elbie took a deep breath. "We don't know who he is. Like I said, he was from our future. She's continued to try to run DNA and fingerprints and it always comes back with negative results."

"But won't he still be born and still go back and change everything?" Lydia asked.

"She thought that she'd figured out a way to stop it. Of course, she never let me in on any of it." Elbie swallowed and tears seemed to be forming in her eyes. "She left two weeks ago. She's normally really good about coming back a few minutes later. But, once, she jumped to 16th century England and miscalculated the jump back. I sat here an entire day waiting for her to make the return. This list she had was pretty long. I don't know specifics, but she was jumping all over the timeline so I was giving her a margin of error. Finally I set up the beacon to call her back. But you came instead of her. At this point, she's either been captured or worse."

"How do you know she just didn't change everything back?"Stiles asked.

"Because then I wouldn't remember anything, because if she changed it all back, then there would have been no reason for her go back again. I just knew it was a trap."

Lydia seemed as if she was in deep thought for a moment. "Where's the list?"

"She made two copies. One is with her. She said she would hide the other somewhere else. Then she destroyed all the files on it."

"Why?" Stiles asked in curiosity.

"She didn't want me to go after her." Elbie seemed to realize something. "Maybe she anticipated this happening. Setting up the beacon at the nemeton was always part of our plan for any jump. Maybe she knew that if she didn't respond to the beacon, that you would." Elbie looked at Lydia. "Which would mean she would hide it somewhere only you would know to look for it."

"Wait," Stiles put a hand up to stop them. "Are you saying what I think you're saying? You want to send Lydia-this Lydia-back in time to save the future?"

"Stiles," Lydia turned to him. "I felt the need to go to the nemeton for a reason."

"But future you tried it and she didn't come back. What makes you think you can go back and do it all by yourself?"

Lydia smiled and grabbed Stiles's hand. "Because I won't be alone, will I?"

Stiles and Lydia stared at each other for a moment before Stiles softly said, "No. If you thought I was going to let you go without me, you'd have to be out of your mind."

Elbie sighed. "I don't understand why it took you two so long to get together."

Stiles eyes widened and Lydia's eyes narrowed and they both turned back to look at Elbie.

"What?" Stiles's 'what' came out high-pitched while Lydia's came out almost a little angry.

Elbie's eyes widened, realizing she may have said too much. "What?" She squeaked out. "I was... quoting a movie...You haven't seen it. Let's go!"

"Go where?" Lydia asked forgetting about what Elbie had said for the time being.

"Our place. Mine and Lydia's. If the list is going to be anywhere, it'll be there."
