All I Need

Younger Now Than We Were Before.

Everyone, Rebekah and Nik included, stood in Lydia's backyard.
"Great, she's missing and completely naked, with this alpha who has already targeted her on the loose!" Sam groaned.
"We'll find her," Nik told him.
"Oh really? What're you supposed to do?" Ellen asked.
"What I do best," he replied.
Nik sped away.
"He's a vampire!?" Ellen yelled.
"Original Hybrid, actually," Rebekah told her, "and he's going to save Lydia's life and protect her. No matter the cost."
Ellen glared at her.
Dean walked and put his arm around Rebekah.
"Why'd you put the dagger in Lydia's knee, Ellen?" Dean asked.
Ellen clenched her jaw.
"That was you!? How?" Bobby yelled.
"Long story," Ellen grumbled.
"You went to a monster to do that, didn't you? A witch. You went to a monster to put a dagger in a girl that thinks of you as her mother's leg! Why?" Dean asked.
"She shouldn't be that monster. It wasn't meant for her knee," Ellen replied.
Dean raised an eyebrow.
"Why?"
"She is going to go insane and kill everyone and everything eventually and you know it," Ellen said, "she will be the end of mankind."
"No she won't. Not with the proper guidance!" Bobby yelled.
"And you think anyone can give her that!?" Ellen yelled.
"Klaus can," Stiles said.
"He's the original Hybrid. He's a true monster," Ellen snarled.
"He's our best shot. He can teach her everything about what she is and she can decide where she wants to go from there. Judging by who she is she'll be okay and so will he," Stiles said, "he's made it clear that he's always going to be there for her and always protect her."
"I thought you were in love with her, Stiles, and here you are standing up for a monster that loves her," Ellen snarled.
"Anyone that loves can be saved. He loves her. I love her. I want her to be happy and safe and I'm sure he wants the same thing. She doesn't have to be happy with me, she just has to be happy," Stiles replied.
Ellen looked down.
"That dagger wouldn't have killed her anyway," stiles said, "she's an original Hybrid and a banshee plus part Liba. You can't kill that. Thank god."
"And what if she's the end of us?" Ellen asked.
"Then she's the end."
Everyone stared at Stiles.
"She won't be the monster you think she will," stiles told Ellen, "and you should probably leave before she gets back and learns you tried to put her down."
Ellen looked down and nodded, "Come on Jo."
"Don't ever come around my daughter again," Bobby told Ellen.
Stiles got a text from his dad.
"I gotta go," Stiles sighed, "you need a ride, Scott?"
Scott nodded and left with Stiles.
A few days later:
They still hadn't found Lydia. Nik had been all over the woods and hadn't found her anywhere. The alpha was out of the woods from what they could tell as well.
Nik sat on the couch, lacing up his boots like he did everyday, when Rebekah walked in.
"You're going again?" She asked.
"I'm not stopping until she's found," Nik replied, "I'm not giving up on her."
Rebekah looked down at the ground.
"You need to rest," she told him.
"I'll rest when I have Lydia back in my arms," Nik told her, "so we can hope that when she is found that she'll forgive me for what happened."
Nik walked out the door and sped away.
It was nighttime and Stiles sat in his Dads cop car with him having dinner.
"You know we'll find her," Sheriff Stilinski told his son.
"I know," Stiles replied, "and I'm here with you for when you get the call."
Stiles' dad rolled his eyes. 
The sheriff got called to a murder scene on the highway by the woods.
"Murder?" Stiles jumped.
Lydia was walking around the woods when she smelt blood and heard a loud siren driving by quickly. She followed it. As she got closer she heard Stiles voice.
Nik walked out of the woods and saw an ambulance and Stiles and his father.
"Did you find her?" Nik asked them.
"No," Stiles sighed.
"What're you doing here?" The sheriff asked Klaus.
"Looking for Lydia, like I do everyday," Niklaus replied.
Stiles looked into the woods and his jaw dropped. The two looked at him for a moment before turning and seeing her.
