"So then I go," I said. "That's obvious." I shrugged.

"If she's going I'm going," Isaac said immediately. Everyone looked at him. "What? She's my best friend. She's not going in there without me."

"Isaac and Y/n then," Scott resolved, shrugging.

---

"You're so perfect for each other!" Allison joked. "You're like the same person. Finish each other's sentences. Know each other inside and out. You basically act, walk, and breathe the same way." She cocked an eyebrow, chuckling.

"Maybe we should just marry each other," I sighed. "Not like there's anyone else here I can stand."

"I'm cool with that," Isaac agreed.

"Tuesday at Ten?" I offered.

"I get to plan the colors and scheme!" Lydia said, waving her hand.

"I'm best man, right?" Stiles put in seriously.

"No, Scott. Duh," Isaac said, rolling his eyes.

"Malia is Maid of Honor," I followed up immodestly. Lydia glared at me. "What? When Allison gets married to Scott you'll have that position. I want to give someone else the opportunity."

She tilted her head. "Fair enough."

"Who's getting married?" Kira asked, sitting down.

"Isaac and Y/n," Stiles said nonchalantly.

"What?!" Kira said. We all looked at each other and laughed.

Oh Kira...

---

"Are you guys like secretly having sex or something?" Malia asked, leaning of reward and slitting her eyes suspiciously.

"Me and Isaac?" I asked, genuinely surprised.

"Duh," she responded.

"Are we secretly having sex?" I asked him.

"In all serious? You and me sexually?" He made a face. "Blehhh!" He made the noise, flicking his tongue dramatically. "Never thought about it once."

"I'm great in bed." I nodded persuasively.

"I'll take your word for it," he said, nodding as well.

And then the conversation ended.

---

"I don't know if you want to..." I began, rubbing the back of my neck.

Isaac rolled his eyes. "You know there's nothing I wouldn't do for you. Pretending to be yr boyfriend I something we haven't done but are close enough to do. Your my best friend."

"Good!" I said, sighing. "This guy is creepy!"

"Come here," he said, smirking and leaning close as he wrapped his arm around my hip. It wasn't pleasant in the way that it would be if I liked him but it wasn't unpleasant in the way that I was t comfortable enough to do this with him. It was like hugging brother.

"Is he gone?" I whispered.

Isaac looked up. "You're good." We pulled back, acting normal. We caught Kira and Malia looking at us, gaping. The rest of the pack was well passed us being weirdly comfortable with each other so they didn't react.

And so continued out time at he club.

---

I leaned forward. "Are you serious?!" I shouted. I was drunk. Very drunk.

"Yup," he mumbled, looking at the sky, leaning back on his hands. He wasn't drunk. The lucky piece of crap.

"WHAT A DUMB IDEA!" I roared, laughing. Then I looked at him seriously. "Do it."

He smiled. "Okay. I'll ask her out tomorrow."

"Good." Then I was out cold.

---

"What are you two?" The girl scoffed.

"Best friends," Isaac answered honestly, shrugging.

"Are you in love with her?" She demanded. I sat there, eyes wide, hand up in surrender. When she asked that I looked at Isaac.

"Who doesn't love their sister?" He asked the girl, eyebrows raised.

The girl scoffed. "Aw!" I joked. He chuckled, rolling his eyes.

"Her or me," the girl challenged." My eyes went wide again, my surrendering hands never falling. He splinted his eyes at the girl but she didn't back down.

"Really? Her in a heartbeat." She scoffed, storming away. "I love youuuu," he said funnily at me.

"I love you too," I responded.

•••

"I may or may not have beat the actual crap out of Theo..." Isaac looked up with a worried look. "Do you hate me?" Theo and I had kinda started dating and I was sure he was good despite Stiles' weird assumptions.

I sighed, ruffling his hair. "You're my best friend. I love you."

---

"Isaac?" I asked over the phone.

No response. Then a dial tone.

I'd asked him why he'd been so aggressive towards Theo recently. Something had gone wrong at the Supermoom and no one would tell me what had happened.

I called again but it went to voicemail. "YOU CAN'T IGNORE ME!" I shouted at the phone, hanging up.

He'd cal back. He always did.

---

Isaac walked up to Theo, a smile on his face. Theo's shoulders squared squared even though Isaac was a bit taller than him, trying to seem bigger.

"If you hurt her," he said with that same pleasant smile and a matching light tone. "I'll snap your neck," he continued. After he finished, his happy, friendly demeanor dropped and he glared at Theo, who took a subconscious step back.

Turns out Theo did break Y/n's heart. On accident.

But Isaac didn't have to kill him. His sister killed Theo for him.
