HARPER TOOK HER KEYS OUT OF THE BACK POCKET OF HER MOM JEANS, THUMBLING WITH THEM FOR A SECOND BEFORE SLIDING THE CORRECT ONE INTO THE LOCK. Stiles rubbed his neck from behind her, becoming impatient with the teenager that they had been hauled with.

They moved into the house as Stiles set down the rules for Derek.

"We're just gonna wait here for Scott. We're gonna sit quietly, and we're not gonna call or talk to anyone," he instructed firmly.

"Do I talk to you two?" Derek asked.

"No."

"Good."

"Fine!"

"Who's going to talk to him?" Derek gestured towards Raphael McCall, a now somewhat permanent member of the household.

"Ah!" Stiles jumped before glaring at Scott's dad, "are you getting taller?"

Harper sighed, remembering that today was the day she, Scott and Isaac were going to sit down and have dinner with him. Raphael was using his time in Beacon Hills to get closer to his son, but he seemed to not mind that Harper and Isaac had also been taken under Melissa's wing. He wasn't so bad when he wasn't working.

"Harper," he nodded at the teenage girl before frowning towards the two boys she was with, "what are you two doing here?"

"Waiting for Scott," Derek replied.

He nodded, "yeah, so am I. We're supposed to be having dinner. I bought extra, you guys hungry?"

"Yeah," Derek and Harper replied at the same time as Stiles said, "no, we're not hungry."

"No, I'm starving," the other boy protested.

"None of us are hungry. Thanks, though," Stiles ignored Derek.

"Okay, well if you're not hungry, Stiles, your friend can still eat with Harper, Isaac and I," the tall man insisted, holding up the bag of food he was carrying, "what's your name?"

"Miguel," Harper replied quickly before Derek could answer himself.

She heard Stiles let out what resembled a small laugh, however he quickly covered it up with a cough. Clearly, he remembered the nickname he had given Derek almost two years ago now too.

The Stilinski boy nodded, "yeah, this is my cousin Miguel. From Mexico, so..." He clapped him on the back for unneeded emphasis.

Raphael hummed in acknowledgement before he began to speak in fluent Spanish. Stiles looked down at Harper while she looked up at her boyfriend, both exchanging looks of alarm. Harper felt her palms get a little clammy, realising they were about to get caught out. Scott's dad was an FBI agent, for god's sake. What did they expect?

She wondered how Stiles or Scott got away with anything growing up, what with both their dads basically solving crimes for a living. At least with her father always being busy in his office and her mother not being the brightest of women, she stood a chance of getting away with stuff.

Harper visibly jumped as Derek replied back, the Spanish language rolling off of his tongue as if it was his first. Derek could speak Spanish?

"Fantastic," Raphael sent a smile in his direction, "egg roll?"

"Hell yeah!"

Stiles began to laugh nervously as Derek walked over to Scott's dad, starting to discuss what Chinese food they wanted. He wiped his hand against his forehead, feeling his skin start to cool from suddenly being let off of the hook.

"Thank god Derek knows Spanish," Harper muttered so only he could hear.

"Yeah, fantastic," Stiles replied sarcastically, just as Isaac came bounding down the stairs.

"Oh, Chinese food," he grinned.

...

"SO, MIGUEL, WHAT DID YOU SAY YOUR LAST NAME WAS AGAIN?" Raphael asked as they all sat around the table, plates of Chinese food in front of them.

Isaac looked up from where he had a mouthful of noodles in his mouth, looking between everybody on the table strangely. Harper shot him a warning glare, telling him not to speak up.

"Oh, it's Juarez... Cinqua... Tiago," Stiles replied casually.

Derek raised his brows, amused.

"That's a mouthful," Isaac teased, leaning back in his seat with a small smirk on his face, "how do you spell that?"

Stiles gave Isaac a look of pure hatred while Derek turned to him, pulling a frown and shrugging.

"Phonetically," Harper answered when she realised Stiles had no clue what to say.

"So, how was school today?" Raphael asked them all, however only really looking between Harper and Isaac.

Isaac sent a fake smile at the new man of the house, "it was fine."

"Same old, same old," Harper replied, "maths, history, English..."

That was another one of the lies that she had told Raphael today, seeing as she, Stiles and Scott ditched straight after the first period to go and find Derek. He didn't need to know that, though.

"Good," he murmured, shovelling a forkful of rice into his mouth.

Harper knew what Raphael McCall was doing- trying to be a better person for his son. She had overheard them arguing a few weeks ago about Harper and Isaac's living arrangements until Scott reminded him angrily that the two didn't have any fathers, and if he wanted to stick around, he had to treat them like he did Scott. The gesture was sweet enough, but it made Harper feel a little awkward.

Derek's eyes flickered over to Raphael's badge sprawled across the table, his brows raising as he gained interest.

"Mr McCall," he spoke up, "you're an FBI agent?"

"He's low level," Stiles responded before the man in question even had a chance, "very low level. He doesn't even have a voice."

Derek ignored the Stilinski boy, "so you investigate murders?"

"Sometimes," Scott's dad nodded, "when it's a federal crime."

"What about fires?"

"Oh my god!" Stiles cried, "I wonder where Scott is. Shouldn't Scott be here by now? We should call Scott."

Stiles' efforts to change the subject went ignored by everyone. Even Isaac had stopped with the amused smirks and digging at Harper and Stiles, genuinely not wanting Derek to find out about his family. He cared about Derek a lot- he was his alpha, the man that had given him a new reason to live and changed his life for the better.

Seeing him as a clueless teenage boy had at first been amusing to Isaac, but now he just felt kind of saddened. He wished Derek remembered him.

"What kind of fires you talking about?" Agent McCall asked.

"Do you know anything about the Hale family?"

...

AS SOON AS THE DOOR TO HARPER'S ROOM CLOSED, STILES WAS SHOVED UP AGAINST IT BY A VERY ANGRY DEREK HALE. Harper's hand went over her mouth, trying to stop herself from saying anything that would set the teenager off further.

"Okay, I didn't lie I just omitted certain truths," Stiles attempted to calm him down, "vital truths now that I think about it."

Derek released Stiles and backed up, "I don't want to talk to you. I want to talk to the alpha. I'll talk to Scott."

Isaac folded his arms across his chest, "do you see Scott anywhere around here?"

Harper sighed, "listen, Derek. You need to calm down before Mr McCall comes up here-"

"Don't tell me to calm down," he yelled at her, causing Stiles to frown.

"Don't talk to her like that."

"Or what?" Derek flashed his blue eyes.

"Stop it!" Harper yelled, shoving Derek's shoulder so he stopped trying to get in Stiles' face, "can you please just try and listen for a second? We're trying to help you!"

"You lied to me!" Seethed Derek, "why should I let you help me?"

"Cause we're the only ones that know how," Isaac rolled his eyes before muttering to himself, "god, normal Derek would have punched you hours ago."

Harper exhaled loudly, "everyone calm down. All this pent-up anger and frustration is clogging my senses."

Stiles opened the door, "my phone is downstairs, I'm gonna go call Scott," he pointed at Derek, "you stay right there, okay? Do not move."

He ran down the hall, his footsteps echoing. Isaac sighed, slumping down into Harper's chair while Derek sat on her bed, staring at the floor. The brunette girl ran her hands down her face, feeling the room slowly but surely start to settle. It was a relief, to say the least.

Suddenly, the bathroom door started to creak open behind her. She looked over her shoulder at the same time Isaac stood up, eyes wide.

"Kate?" Horrified gasps left both teenager's lips.

Meanwhile, Derek sat on Harper's bed, staring at the woman as if it was a relief to see her. That was probably the most confusing part, just above the fact that Allison's not-so-dead aunt had been hiding out in Harper and Scott's joined bathroom for god knows how long.

Harper took a step back, ready to run, however, the blonde haired woman showed no mercy, lifting her arm and striking Harper across the face. The petite girl fell to the ground quicker than you could say 'bloody hell', smacking her hip on the floor harshly. She looked back up at her, her lips still parted in shock.

Isaac growled furiously, rushing forwards with his teeth bared, only for Kate to stick her hand out, extended claws pressed against his neck, daring for him to lay a finger on her. The werewolf swallowed, looking down at her hand that could be seconds away from ending his life.

"Kate?" Derek repeated, standing up.

"Hello, handsome," she grinned, letting go of Isaac and walking towards him, "you might want to come with me if you want some actual answers."

Derek looked down towards Harper who was climbing up off of the ground and Isaac who looked like he was seconds from exploding. He looked back a the woman and nodded.

"Derek, no," Harper shook her head quickly, "you can't trust her! Who do you think lit-"

"Don't listen to them, Derek!" Kate ordered, a sickly sweet smile on her face.

She reminded Harper scarily of Derek's last psycho ex-girlfriend, Jennifer Blake.

"I don't trust you guys," Derek spat as he began to follow Kate towards the window, "her, I trust."

"You're making a mistake," Isaac glared.

Derek placed himself over the edge of the window, "you don't know me."

Then, he jumped, disappearing alongside the woman who had been proclaimed dead over a year ago. Stiles entered the room, slipping his phone into his pocket and looking up, pausing when he saw no Derek.

"Um, where did Derek go?" He asked nervously.

"Kate," Harper looked back at her boyfriend anxiously, "she came in here and she convinced him to go with her."

"Did she do that too?" He pointed at the red mark on Harper's cheekbone that still felt as if it were on fire.

Isaac nodded, "she had claws too, but she's not a werewolf. I don't know what she is."

Stiles pulled his phone back out, hitting one of the three contacts he had saved in his favourites, "Scott? I take back what I said. Maybe we do need to start worrying about Kate..."
