"We have a problem."

What had been a peaceful breakfast was quickly ruined by the intrusion of Peter, who for some reason always knew where the spare key was for the back door. The older werewolf had stormed through the door, throwing his jacket on the back of one of the chairs. Stiles looked over from where he was next to Luna, entertaining her with balancing a spoon on his nose. As Luna kept trying to bop the spoon off his nose, Stiles said slowly, "Um, Derek's...somewhere."

"Oh. You." The tone Peter used made Stiles glare immediately in response.

"Yeah, me." He took the spoon off his nose and handed it to Luna, who banged it on the table. "Look, we're around each other a lot more, so we should work out our-"

"I don't have time for your pussyfooting around," Peter said as he walked by Stiles, flicking his forehead. Stiles flailed trying to get his hand away from him, and he scowled as Peter continued into the house.

"You're a dick," He called after him, picking up Luna and trailing after the annoying intruder. When Peter found Derek in the bathroom shaving, he pushed the door the rest of the way open and leaned on the doorway.

"Derek, we have two tickets sending that moron and the baby out of town. The pact failed." Derek turned and narrowed his eyes at Peter. There was an air of mistrust around him as he set the razor down on the counter top, lifting up a towel to wipe his face.

"What happened."

"Alicia failed to mention her connections to Beacon Hills to us, and it turns out she has an entire family living here. Parents and brother. Well, I should say father and brother, because Deucalion sent her mother's head to her in a box last night." Peter said it as if it were normal news, and Stiles moved to put his hand over one of Luna's ears, pressing her other against his chest. Somehow he felt the baby shouldn't be exposed to this sort of violence, even if the family acted like it was normal.

"Damnit," Derek muttered as he threw the towel on the counter, picking up his jacket off the hook near the shower. "I can't leave Luna with Stiles."

"Don't tell me I have to remind you that Luna is dead if we enter a turf war with the Alpha pack," Peter whispered vehemently, his eyes locked on Derek's. "Stiles will be going out of town to Laura. Stiles will drop her off." There was obvious displeasure in Derek's expression. Even though he was normally hard to read and maintained an excellent poker face, Stiles almost felt an aura of sadness around him at this sudden development.

"I don't mean to interrupt," Stiles interjected, and the two looked towards him. "But I'm not going out of town on a sudden voyage. Besides, if this is so dangerous..." He paused.

"Go on," Peter probed, expressing vague interest in Stiles' contribution to the conversation.

"Well, if it's so dangerous going to...war with an 'Alpha pack', shouldn't you all skip town? This kid has already lost a mother, she doesn't need her father to go get killed over a pissing contest. I mean, yeah, you've been here awhile but your prosperity should really come before property wars."

"You don't get it. We have something the Alpha pack wants and we can't give. What we have would mean the end to your lovely little useless life as it is."

"I don't care if things change for me," Stiles argued, his tone combative. He looked at Derek, his hand still firmly over Luna's ear. She didn't seem to mind being pressed against Stiles' chest - he didn't realize how calmed she was by his heartbeat. "You don't abandon your kid. So take the ticket and get out of here. I'll do whatever Derek was going to do."

Peter stared blankly at Stiles, and then burst out laughing. He put a hand over his mouth, the amusement too strong for him to suppress. "Oh, that's a good one." Derek shook his head, a slight smile on his lips.

"I appreciate the offer Stiles, but you really..."

"What? Yeah, I'm not super strong. I'm not even strong for a human. But I'm smart. I know it might not come across all the time, but I really- I'm really smart." He looked at Peter, who was still chuckling. "Seriously, I'm really smart. I could run laps around this guy's intelligence." He pointed at Peter, taking his hand off Luna's head finally. She looked up at him with a strong curious expression, but went back to pressing her ear against his chest. Peter looked insulted, suddenly no longer laughing.

"Watch it."

"No, maybe he's got something," Derek motioned to Stiles, looking at Peter. "Maybe we could use him. And he's right, I think the safest place for Luna is with the pack. With me."

"If you say so," Peter frowned, and motioned for Stiles to move. Stiles walked down the steps, the other two trailing behind him. "The issue we have right now is we need to get what's left of the Boyd family out of the vault. We're not sure if either of them are still alive, but as long as they're captured, Alicia's wavering on her alliance."

"What vault," Stiles asked, and Peter took a blueprint out of his pocket. He handed unfolded over Stiles' shoulder, and Stiles held it up as he walked into the kitchen, laying it out on the kitchen table. It looked like an old bank blueprint. "Beacon Hills First National Bank...This place shut down years ago. It's huge. Hey, this must be where they had me. I remember, right here. That door is reinforced with bars." He pointed at a door on the map.

"Good to know," Derek said as he took a pen out of a cup on the counter, writing BARS on the blueprint by the door. "Anything else?"

"Well, this place isn't secure anymore. What I mean, is the electricity isn't running. Most banks depend on back up generators when they lose power because everything's being protected by processes run on electricity," Stiles pointed at where the largest vault was, and then tapped it. "I bet they have them there. Which means the only thing keeping us from them is probably a lot of heavy doors, and probably a ton of steel reinforcement that we can't get through. But if we can find the backup generator, and turn the electricity back on, we could totally take the place over from the security room. If everything's still working, that is. I mean, this place has been closed for eight or so years, so we're working with primitive tech. But it'd take them by surprise. I doubt they're even watching this section of the bank. And from when I was there, the vents are large enough to crawl through - we could crawl through the vents to the security room, and then someone else could jump start the power with the generator. It'd give us enough time to have someone jump out of a vent near the vault, get the two people, pull them back up in the vents, and get out. I mean, it's just a thought. I'm not positive on any of this..."

"No, it's actually really good," Derek mused out loud, looking at the blueprints. "You sure you can handle the security room stuff? I mean, if my mom okay's this?" Derek gave Stiles a hopeful glance. He felt obligated to respond positively, something in Derek's puppy-like expression inspired him.

"Yeah, I'd totally be able to handle it. I mean, I dabble in all that tech stuff."

"I hate to break the love," Peter put his hand on the blueprint, pointing at the security room. "But you're basing this entire operation on an assumption they're not using this room. What if they're using it? What if they have them in another vault?"

"Well, two things," Stiles pointed at the left wing of the upstairs. "I remember the reason this place was closed was because there was damage to the foundation when someone was trying to break into vaults. My dad mentioned it. The explosive damage to the integrity of the place was too extensive, that's why they rebuilt the building somewhere else. So all these vaults are useless. This large vault is in the basement, and no where near the damage. And I'm just guessing the security room isn't being used because when they shut down banks, they probably lock that area up after destroying all the files. And why would they use that area? It's not like there's a place to hook up their wifi there. They probably are just using the place because it's the one building the city has been avoiding demolishing because it'd cost too much."

"What makes you think that the wiring in that place can be used after an explosion?" Peter challenged, looking at Stiles. Stiles' mouth gaped, trying to grasp at a reason.

"I mean...I guess, maybe it wouldn't be working but, I mean, what choices do we have? It's better than storming inside and going, hey, we're here, let's dance! What's your idea, huh? You have a better one?"

"If it were up to me, we'd just take out the building. But Talia is convinced that two lives should be saved instead of sacrificed. Fine, propose this idea to Talia." Peter put a hand through his own hair, glaring at the blueprint and sighed. "Guess we'll find out if it works."

Derek retrieved his phone from his pocket, walking off into the living room as he made the call. Stiles looked at Luna, who was still listening to his chest. He poked her chubby little cheek, and she looked up at him with those deep green eyes. "Hey," He said with a smile, and she smiled back at him.

"Papa," She said loudly, patting Stiles' chest. Stiles looked a bit confused, and then he pet her head.

"No, no, I'm not papa," Stiles cooed, kissing her forehead. She smiled wider, reaching her little arm up to tap his chin. "But you're the cutest Hale."

"Papa," She insisted, and then looked at Peter. Peter was giving Stiles and Luna a clearly cynical look. Stiles followed where she was staring, and then he squinted at Peter.

"What."

"You like Derek, don't you? Why don't you just ask him out. So the rest of us don't have to deal with whatever weird tension you two are having."

Stiles could feel his face turning red, and he glared at Peter with a mixture of shock and denial. "I...you're a dick."

"And you like dick. Come on, live up to it."

"I...the baby," He said, his voice tense. "Don't talk about that around the baby." He covered Luna's ear, and she smiled as she took it as a signal to put her other ear against his chest.

"What about the baby? Because she probably thinks you two are dating already. Papa Stiles. Anyways, it's disgusting. Let's quit this discussion."

If he had looked displeased before, Stiles was absolutely livid now.

"You homophobic bastard, you know, gay people should deserve the same rights and respect that heterosexual couples get." Peter put up a hand to stop Stiles before he could continue on his speech promoting gay rights.

"No, Stiles. I don't find homosexuality gross. I find the idea of my nephew dating you gross. I personally think he could do way better, but I guess whatever floats his boat." Peter looked Stiles up and down, then made a grimace. "Even if it is you. Ick."

"I'm cute," Stiles insisted, and Peter chuckled as he walked over to the fridge to get a beer.

"Right. It's always good to have confidence." The sarcasm was heavy in his voice as he popped the top of the can. Stiles turned and walked out of the room with Luna, kissing her head angrily. She made a happy noise as she gripped his shirt.

"I am too cute. Your dad's uncle is blind." He muttered angrily. "I'm banning him from my house after this is over, Luna. Between me and you. Don't tell him."

Luna stared at Stiles as he talked to her, sensing the tension in his voice. She patted him reassuringly, making him feel a little better.

"Yeah. See, you agree with me. This is why I like you."
