Stiles POV: Stiles and Selene were at Derek's loft talking to Cora. Selene was relaxing while Stiles paced. Selene's eyes finally seemed to go back to their regular color and she seemed calmer now too.
"They were there for two days waiting hiding. That's what we're taught to do when the hunters find us… hide and heal" Cora said continuing her story on Derek.
"Okay so is two days standard then or are we thinking Derek's on like some extended get away?" Stiles asked about Derek's disappearance.
"Why do you care?" Cora asked turning from the window to face Stiles.
"Why do I care? Let's see… because over the last few weeks my best friend's tried to kill himself. His boss nearly got ritually sacrificed. A girl that I've known since I was three WAS ritually sacrificed. Boyd was killed by Alphas I… do you want me to keep going? Cause I can all right? For like an hour" Stiles stressed.
"And you're mated to a werewolf! This is your life now. You think Derek can do anything about any of this?" Cora said getting upset.
"Well since he's the one everyone seems to be after it's more like he should do something about it yeah."
"Stiles losing one of your pack… at least for a regular pack it's like losing a limb a part of yourself. Pack is meant to be safety and family. Derek feels like he failed Erica but to be forced to kill Boyd it's ripping him apart inside" Selene explained.
"I don't know. There's something different about him now. He wasn't like this when we knew him" Cora said.
"What was he like?" Stiles asked.
"A lot like Scott actually. A lot like most teenagers… unbearably romantic, profoundly narcissistic tolerable really only to other teenagers" Peter said walking down the stairs.
"And so what happened? What changed him?" Stiles asked.
"Well the same thing that changes a lot of young men… a girl" Peter said shifting his gaze from Stiles to Selene.
"You're telling me some girl broke his little heart? That's why Derek is the way he is?" Stiles asked stepping subconsciously between Selene and Peter not liking the look Peter gave her.
"Do you remember Derek before he was an Alpha had blue eyes? Do you know why some wolves have blue eyes?" Peter asked Cora.
"I just always thought it was like a genetic thing" Stiles said.
"If you want to know what changed Derek you need to know what changed Derek you need to know what changed the color of his eyes" Peter said.
So Peter started a story about a teenage Derek meeting a girl named Paige. Selene sat in Stiles' lap and got ready to listen.
"Okay so if Derek was a Sophomore back then how old was he? How old were you? How old are you now?" Stiles asked.
"Not as young as we could have been but not as old as you might think" Peter replied.
"Okay that was frustratingly vague. How old are you?" Stiles asked Cora.
"I'm 17."
"See that's an answer. That's how we answer people."
"Well 17 how you'd measure in years" Cora responded.
"All right I'm just gonna drop it. What happened to Derek and the cello girl?"
"What do you think happened? They were teenagers. One minutes it's 'I hate you don't talk to me.' The next it's frantic groping in any dark corner they could manage to find themselves alone for five minutes. Their favorite dark corner was an abandoned distillery outside of Beacon Hills."
"All right hold up. How do you know all this? You just said that they were alone" Stiles said.
Peter leaned forward.
"Back then I wasn't just Derek's Uncle. I was his best friend his closest confidante. That's how I know."
Peter explained how Kali, Ennis, and Deucalion all met at the distillery and Ennis just having lost a pack member to a hunter kill. Ennis carving the sign for vendetta in the metal wall.
"Our mark for vendetta" Peter explained.
"Man you guys really take that revenge thing to like a whole new level don't you" Stiles said.
"You remember what I just said losing a member of your pack was like…" Selene said softly.
"They wouldn't even let him see the body" Peter said.
"I don't get it. What does this have to do with Derek?" Cora asked as Peter looked out the window.
"Everything. It's never just a single moment. It's a confluence of events. Personally I looked at Ennis' circumstances I saw profound loss. Derek…saw something different. He saw opportunity."
"Opportunity? To do what?" Stiles asked.
"To always be with her."
"The thing was he had this constant fear. He was obsessing over it thinking about it all night all day always on his mind" Peter said as he continued his story.
Peter talked about Derek wanting to turn Paige out of fear she'd find out what he was.
"I kept telling him not to do it. Every day the more he thought about it the more convinced he became. You know teenagers. I bet he even blames me. He's probably convinced himself the whole thing was my idea."
Soon Peter started to talk about how the druids were advisors to the packs their emissary.
"They keep us connected to humanity. But they're a secret even in the pack. Sometimes only the Alpha knows who the emissary is. Derek and I had no idea about Deaton" Cora explained to Stiles.
"Or his sister Morell" Peter said as he paced slowly.
"She's an emissary too?" Stiles asked slightly freaked.
"For the Alpha pack" Peter confirmed.
"Our guidance counselor? Why the hell don't you people tell me any of this stuff huh? I shared some really intimate details with her" Stiles said still freaking.
"And did she give you good advice?" Cora asked.
"Actually yeah" Stiles said after he thought about it.
"That's what they do. That's what Deaton used to do for Talia" Peter said.
Then Peter explained the Alpha Derek wanted to turn Paige was Ennis.
"Ennis? Why would he choose him?" Cora asked.
"Why not? Ennis needed a new member for his pack. Paige was young and strong. Doing a favor for Derek meant Ennis would be in good with Talia. Back then everybody wanted to be in good with her" Peter said.
"He doesn't remember it was Ennis does he?" Stiles asked.
"If he does he keeps it to himself" Peter replied.
"So then what happened? Did he turn her?" Stiles questioned.
"Almost. He came at Ennis. A 15 year old boy against a giant. There was no reason for him to fight. She'd already been bitten."
"So did she turn?" Cora asked.
"She should have. Most of the time the bite takes. Most of the time."
"When you offered it to me you said 'if it doesn't kill you'."
"If."
Peter told them how the bite didn't work Derek asking what was wrong.
"He knew the answer though it didn't matter that she was young and strong some people just aren't made for this. But she fought she struggled desperately trying to survive."
Peter said Derek killed her to end her pain.
"I remember taking her body from his arms to the woods to a place I knew it would be found… another in the long line of Beacon Hills animal attacks."
"And what about Derek?" Cora asked clearly upset for her brother.
"Taking an innocent life takes… something from you as well a bit of your soul… darkening it dimming the once brilliant golden yellow to a cold steel blue… like mine" Peter said then he looked up at them letting his eyes change to the blue of his wolf.
After that Peter left them and Stiles, Selene, and Cora all sat hunched together.
"What? What's this… what's this look on your face?" Cora asked.
"What look?" Stiles asked back.
"The kind of look that makes me want to punch you" Cora replied.
"Oh my god. You are so Derek's sister. I forgot."
"Well what is with the look?"
"I just don't believe him. All right in Ms. Blake's class we're reading 'Heart of Darkness' and it's in first person right? Narrated by Marlow. The thing is that he's… he's an unreliable narrator. You know the details of it have changed you know just because of his perspective" Stiles explained.
"Well then we heard the story from Peter's perspective" Cora said.
"Right and I don't think we got the whole story."
"So what are… are you just gonna ask Derek about the girl he fell in love with and then killed?" Cora asked.
"If I have to… yeah."
Selene POV: She sat and stayed quiet through all of Peter's story hearing every lie he told. Wondering what he real motive was for telling the story with only half truths.
"You don't have to ask Derek… what Peter doesn't know is I was also one of Derek's confidantes. He was… one of very few true friends I had. Peter told mostly the truth. But what he changed was… Derek never wanted to change Paige. He never worried about her finding out the truth. Peter… he was the one to make Ennis change her it was all on him" Selene said softly.
"Peter's always been the way he is manipulative and cunning. I just never understood what he had to gain in making Ennis turn Derek's girlfriend. Peter only does stuff to benefit himself" Selene said and no one had anything to say to that.
