Sister Knows Best
Author's Note: I totally wanted to try out the character of Cora and see if Derek's sister could introduce some interesting new chemistry in how he and Stiles relate.
I gotta say though, I never saw that plot twist coming. Derek has this younger sister we've never heard anything about.
Also, RIP Erica Reyes. Sucks her character had such a short run. I kinda liked Catwoman, but I guess that's just the kind of show Teen Wolf is.
Warnings: Given canon divergent
Pairing: Sterek

Cora walked around Derek's studio, still feeling oddly out of place. She was glad she and her brother had been reunited. There were things she couldn't voice yet, all the terrible memories of being held captive by Deucalion all those years.
Derek had no idea what he was up against. The alpha pack had kidnapped her from the fire all those years ago. Deucalion had always had his sights on Beacon Hills from the shadows.
She still couldn't talk about it, all the terrible memories, the things the alphas had subjected her to. Derek had told her everything would be alright now.
After she and Boyd had gone on that mad killing spree around town some part of her had tried to anchor itself in Derek. She attacked a few people, but she had better control than Boyd.
Eventually she came to herself, thinking of Derek and their mother. Why was she doing this? She'd cut down some innocent old lady with her claws.
"Derek," she whispered, looking at her blood-soaked nails, her shaking hands.
"Its alright Cora," Derek told her gently, stepping out of the shadows.
"No Derek," she shreiked. "It isn't alright! I killed innocent people!"
"You didn't know what you were doing," Derek said softly. "Cora, please. Come with me."
She did better than that. She ran forward arms outstretched, tears pouring down her face, into his own embrace. Derek held her against him, wracked with emotions, breathing in the scent of the sister he'd been sure had died.
"Its really you," Derek whispered, holding her tighter to him.
Cora smiled a little, recalling their reunion. Derek was such a good brother. He'd forgiven her everything, assured her that none of it was her fault.
She looked over at said brother, standing over his stove, stirring something that was beginning to smell awesome. It was hot chocolate.
He noticed her looking and gave her a winning smile. A real Derek smile, just like she remembered.
"I remember how much you like hot chocolate," Derek told her. "Remember how I used to make it for you?"
"How could I forget?" Cora asked with a smile. "You always made the best."
"Cora," Derek spoke softly. "I'm so glad I have you. That I don't have to be alone anymore."
Derek walked over with two mugs, handing her one. They sat down next to one another on his bed in the corner of the studio. It really wasn't a very big apartment, not like their old house.
"What have you been doing all these years?" Cora asked him.
Derek shrugged.
"After the fire I went to New York. I came back here when I heard about Laura's death. I killed Peter and became the alpha, except he managed to use Lydia to bring him back. We fought Gerard and a kanima."
"Gerard Argent?" Cora asked in mild surprise.
"Who else?" Derek muttered.
A knock suddenly came at the metal door. Derek could smell the visitor immediately. It was his scent. What did he want?
Derek stood up and walked to the door, pulling it open, giving Stiles his best death glare.
"Heya Sourwolf, what's goin on?"
"Could you not call me... " Derek began, but Cora cut him off.
"Oh my gosh that is so cute!" she enthused. "Sourwolf!"
Stiles looked at her in mild surprise, blinking a few times.
"Uh Derek, isn't she a little young for you?"
"She's my sister Einstein!" Derek snapped at him.
"Ohhh," Stiles replied, giving her a little grin. "You're his sister."
Cora smiled at him.
"You are so adorable," she told Stiles. "Has anyone ever told you that?"
Stiles beamed at that and started to reply, when Derek clamped a hand over his mouth.
"He's adorable?" Derek shot at her. "Try totally annoying and useless, and if you're thinking about dating him... "
"Don't be silly Derek," Cora said with a laugh. "Of course I'm not thinking of dating him! I was just commenting what a interesting and different person he is."
"Oh he's different alright," Derek smirked.
Stiles hacked into to Derek's hand.
"Ew!" Derek exclaimed at him, jerking his hand away. "I'm infected with your spit now."
"Teach you to try to stiffle my voice," Stiles retorted with a grin. "Besides, I owed you for that punching my hand deal."
"Funny," Derek smirked. "I seem to recall you holding your hand in front of my fist. I guess I made a mistaken assumption... "
Cora watched them argue back and forth with a surprised look. They were squabbling about the smallest little things, almost like a married couple. Her surprise was replaced with mild amusement.
"Why did you come here anyway?" Derek asked him suspiciously.
"I came to ask how it was going with finding your sister. Scott wanted to know. Well I see you found her, so... "
Stiles made for the door, but Derek grabbed his arm, scowling with displeasure.
"You are very rude," he said in a low growl. "I'm not finished with you yet."
"Derek let me go!" Stiles struggled against him.
"Derek," Cora said with a smirk. "Come on, really?"
Derek's eyes widened under her stare. What exactly did that smirk mean? He released Stiles' arm without even thinking about it.
"Geez Sourwolf!" Stiles snapped at him. "Next time you grab my arm like that why don't you just twist it off? Fragile human here!"
"You really want me to twist your arm off?" Derek asked, looking at him with raised eyebrows.
"Oh stop you two," Cora snorted. "Its obvious to me what's going on here."
Stiles and Derek looked at one another strangely.
"Derek your sister is kinda scaring me."
"That's wise Stiles," Cora told him with a smirk. "I could probably rip your throat out, seeing as you're only a human and all. Why would I do that though when its obvious you like my brother?"
Derek looked at her like she was crazy.
"Don't look at me like that Derek," Cora told him with a knowing smile. "There's enough sexual tension between you two to bake a cake, so why don't you just do something about it already?"
Stiles looked at Derek again, raking in that sculpted, filled out body beneath thin fabric.
Derek gave Stiles a weird one over, taking in the younger man's hair, those cinnamon eyes that were always so intense. His breath hitched slightly.
"Well I think I'll be going," Stiles said, sprinting for the door.
Derek definitely didn't stop him this time. It was all way too awkward, and in front of his sister no less.
"Cora I love you and all, but I think maybe you're mistaken about Stiles and me. We're just friends. We play around like that all the time."
"Yeah whatever Derek," Cora told him. "Deny it all you want, but I'm a werewolf too. I know what I sensed between you."
Derek looked at the door Stiles had just ran out of with a small frown, inhaling to drink in the boy's lingering scent. That scent that always drove him crazy! If he didn't know any better...
"Derek why don't you do something about it?" Cora asked. "What's the worst that can happen? We all need someone."
Derek folded his arms defensively, but he couldn't ignore his sister. If anyone could get through his walls it was her.
"Something like what?" he asked curiously. "What exactly would you suggest?"
"I don't know, maybe take him somewhere? Like a date."
Derek thought about that. Actually it wasn't the first time he'd thought about it. He just never really knew what he'd say to Stiles about wanting to hang out with him.
"You know I have another idea," Cora broke into his thoughts. "Why don't we invite him for dinner?"
"That isn't too bad of an idea," Derek agreed. "Its a start. I'd feel a lot more comfortable starting with something like that."
"Awesome!" Cora enthused. "You two would be so cute together"
Derek's expression soured considerably at that, but only because he didn't want to admit his sister was right.
