Greenburg stumbled to obey before Hale asked for someone else, shoving papers at people. Lydia flipped her's over, starting just as Stiles got his, smiling when he realized that Harris hadn't taught any of this but it had been in the book, Lydia's pen slowing down as she reached the halfway point. Twisting his pencil around in his hand, Stiles grinned, filling in the answers as accurately as he could.

Hale took the test as they finished, grading them faster then Scott had ever seen, his eyes straying from the paper as the hint of ashes and smoke reached his nose. Shaking his head, he stood to turn in his test, catching Hale twisting a ring that was obviously too big around on their right index finger, before spinning a pen to continue grading.

"Who are you?" He asked quietly, drawing Issac's attention, "Why are you here?"

Hale smiled, "I'm not a hunter and I'm not here to kill anyone. What matter is it to you? I lived here before you were born and I was forced away. Tell Derek Hale that Peter's sister gave me free reign as long as I did nothing to disobey pack rules."

"Peter's sister?"

"His mother, if you wish to be concise." Gray eyes glowed for a moments, "Please return to your seat Mr. McCall."

Derek stared at them after they finished telling him about their experiences with Hale, he nodded once Scott told him about his mother's ruling on the outsider.

"I know who it is." He sighed, "It would explain a lot, she's always been a little odd according to what I remember from before. Her name's Melissa Hale or Lissa Hale if you listen to her. She works or worked for a branch of the military that focused on taking care of supernatural problems, used to vanish for years at a time after her daughter was taken."

"So you know her?" Siles asked curiously.

He shook his head, "I know of her. Peter knows her, Lissa Hale is his wife."

"Are you talking about my big sister?"

They turned to face the voice as Stiles choked.

"Stephanie?"

She grinned, "One and only. Unless there's another me, in which case you need to talk to Lissa because she's the one that goes around cloning people and replacing them when they die, though I think she had to give the military the rights to that so she could leave. Unless they accepted the brownie recipe, they some good brownies."

Erica stared at her, "You snuck up on us."

"Yes, I do that." Stephanie agreed calmly, "That I do."

"You just used Yoda." Stiles grinned, "I knew there was a reason I chose to sit with you."

Stephanie raised an eyebrow, "You sure that it wasn't because you couldn't be left alone for more then a minute with out looking crazy."

Derek interrupted their argument, "I wasn't told that Lissa Hale had any family left alive."

"That's okay, she doesn't really." Stephanie stepped through the unoccupied chair, "I've been dead for almost twenty years, our brother died fifteen years ago, and Tori died six weeks ago. The same time Lissa tracked down the people who stole her daughter and started trying to figure out how to get her back."

"You're a ghost?" Boyd asked curiously, "Who met Stiles at a coffee shop."

Stephanie grinned, "I like them so much more then schools. I can't touch anything so homework is a little bit of a hassle, not to mention classwork."

"What is Lissa Hale's stance on the Argent family and the Alpha pack?" Derek asked interrupting the banter, "Does she know what she walked into?"

"Yes," Stephanie's face darkened, "Victoria Argent was our sister, she was also the one that stole Lissa's daughter, Allison Hale. The Argent family as a whole now owe the Hale family for what they have done, the death of Kate Argent did not absolve them of the murder of the Hale pack, an equivalent exchange has to be made, the return of Allison Hale is a must. The Alpha pack would be better discussed as one once the Argent threat is removed."

"Peter has a kid?" Scott asked eyes wide.

Stephanie snorted, "Peter's had a kid for years, but they took her and now he's going to get her back."

Allison rubbed her eyes as she opened the door, scowling when she saw who accompanied the woman, "What do you want?"

"Is that anyway to treat a guest?" Peter Hale replied calmly, "We're here to see Chris, tell him it has something to do with Victoria and her family."

"Mom's dead, she didn't have any family." Allison snapped.

The woman tugged a piece of paper out of her folder, "Incorrect, she had is survived by her older sister. All the correct paperwork is here, if you could get Chris Argent."

She nodded taking the paper and shutting the door in their faces as she moved through the house to the study that her dad had enclosed himself in after her mom had died, reading over papers that looked like they would crumble in his grasp. He waited until she was done speaking to lead the way back down stairs and let them in, heading toward the living room.

"Who are you and how might I help you?" Chris asked curiously.

The woman smiled, "My name is Lissa, Tori was my younger sister, I believe you were the one to drive her to the incident that ended with our estrangement."

Chris nodded, "I remember, we had just met when she begged a favor from me. What are you doing here now?"

"What do you know about Allison's adoption?"

"Not much, it was private and the details were taken care of before she told me anything." He replied as Allison bit her lip.

Lissa put the folder on the table between them, "You will want to read this, I know that you have no reason to trust me."

"That's a lie, Melissa Hale." He grinned as her nose twitched at her name, "You were one of the best soldiers that most of the country will never know about, the one sent after hunters that went to far. Did they really let you go? Or did you find a replacement for yourself?"

"I got out, trained humans to take my job." She smiled, "Was given more money then I ever hoped to see."

Chris laughed, "I would assume. This is going to tell me where Allison was stolen from?"

"Dad?"

Seventy-two hours after Derek's Uncle entered the house and told them it was being destroyed, Danny and Stiles call a meeting together with a slide show.

"We did some research on Lissa Hale," Danny started, "Who she is. The works, Stiles asked me to hack into her past."

Jackson snorted, pulling Lydia closer while the others settled on the couches they had dragged into the subway station through the last couple of months. Derek leaned against the back wall, head tilted to the side.

Stiles pointed to the first slide, "We know that Lissa grew up somewhere close to the beach, her father died when she was a kid leaving her mom and three siblings. Stephanie died first, the police called it an animal attack."

"What isn't on file is that Lissa was sent on a mission to retrieve the President's kid after they where taken by a Wolf gang, hunters were called in to give her the information she needed. She got the kid out, but she missed the Alpha and three others. Stephanie took a shortcut home from a date and was killed to send a message."

Scott whimpered when the crime scene picture flashed onscreen. Blood spattered everywhere.

"Lissa took it upon herself to go after them, she hunted them down and at some point ran into the Hale pack, who were doing the same thing. We know that she fought and was bitten before killing the Alpha, Alpha Hale allowed her to join their pack as long as she followed their rules. Peter married her six months later. Periodic missions up until she's pregnant and then when her daughter goes missing both she and Peter change. Lissa goes for months, a couple years, on missions. Peter falls into research."

Danny looked up taking over, "The day before the Hale fire, Lissa Hale was called because they had found the body of her younger brother, a solider in Afghanistan who had been missing for almost a year. She went to collect him from the base, the fire didn't make it to her until both Derek and Laura left."

"She spent the intervening years looking for Laura and Derek, but also for her daughter. We also know that last month she retired from the group she had been in, leaving people she had trained in her place. Her reason for coming here was two fold, Derek's name popped up on her search and Victoria Argent was her final living sibling, she's also the main suspect in Lissa Hale's list, the one she made to keep track of who might have taken her daughter."
