It started with a lie—one she told herself.
She didn't mean to fall into something with Scott. It began as glances across the training room, long talks after pack meetings—an understanding that felt... easy. Nova had always been everything to her: intensity, fire, loyalty, devotion. They were each other's world. So much so that Allison still couldn't understand why she ever let herself fall for Scott. Maybe it was the comfort, the safety, the familiarity that made it so tempting. Scott made her feel seen in a quiet way, something she hadn't realized she craved. But it was nothing like what she had with Nova.
The cheating started slowly. A kiss after a heated sparring match. A shared bed one night when Nova was away, too tired and hurt from a hunt. Allison told herself it was just confusion. She and Nova were complicated, and this was just a mistake. During the same time, she was also continuing to sleep with her girlfriend, and she loved being with Nova. After they had made love and Nova lay curled up beside her, Allison would often find herself staring at the ceiling, wondering why she had ever turned to Scott in the first place.
But the mistake kept happening, over and over, an indulgence turned habit, a betrayal turned pattern. Even when guilt gnawed at the edges of her conscience, even when she looked at Nova and felt the sting of deceit, she still kept going back to Scott. Allison tried to justify it in a hundred different ways, but none of them held weight against the truth she refused to face: she had chosen to hurt the one person who had loved her unconditionally.
Allison remembered the moment it all fell apart. Nova's voice was icy calm, but her eyes glowed with the storm she barely held back. She had walked in on them, Scott and Allison, tangled in sheets, in a room Allison swore she'd locked. Nova didn't scream. She didn't cry. She just stood there. Watching.
"Wow," Nova said, voice eerily steady. "Guess I needed the visual confirmation after all."
Allison scrambled for words, heart in her throat. "Nova—wait—I didn't mean for it to happen like this."
Scott echoed her with a stammered excuse, "We didn't— It just… happened."
Nova's gaze didn't waver. "You're seriously trying to make excuses?" she asked, her voice dry with disbelief. "Don't bother." Her voice dropped, sharper now. "So all those times you canceled dates or said you were hunting with your dad... were you actually with Scott instead?"
Allison looked down, guilt written all over her face.
Nova's lips curled bitterly. "And of all people... you picked Scott? Really?"
She turned her fiery gaze to him, voice cracking with betrayal. "He's my brother."
Then her expression hardened. "He was my brother."
Scott's face crumbled, a storm of guilt and heartbreak washing over him. Allison looked down, her shame radiating off her in waves. Neither dared meet Nova's eyes.
Then she turned and walked away.
Allison didn't sleep that night. Neither did Scott. They tried texting her, calling her. Nothing. It was Lydia, Stiles, and Derek who blew up both their phones the next day, demanding to know what the hell had happened. Their messages came rapid-fire, asking if what Nova told them could possibly be true and, if so, what the actual hell they had been thinking.
Allison read the texts with trembling hands, her stomach churning. The fact that Nova hadn't even given them a chance to explain, that she'd gone straight to the others, it hit her harder than she expected. And somehow, that hurt more than all the yelling ever could.
To make matters worse, someone had plastered pictures around the school—photos of her and Scott tangled up in undeniable betrayal. The Argent name, her family's legacy, dragged through the mud in every hallway whisper. Scott tried to lie, of course, saying it was all a setup. But Lydia and Stiles confirmed everything, backing up Nova's version. The student body turned cold. Eyes followed Allison and Scott wherever they went, not with curiosity but with judgment and disdain. They were pariahs now, paying the social price for a betrayal that could never be undone.
The fallout was nuclear.
They weren't just shunned—they were exiled. Even the ones who tried to remain neutral couldn't look at them the same way
Allison remembered trying to apologize, more than once, but Nova never gave her the chance. And then came a blow that stung more than she expected: overhearing Nova quietly tell Lydia that she had a one-night stand with a girl. A total stranger she met in the Beacon Hills Preserve. The casual mention hit harder than expected, a slap of reality that Nova was moving on in ways Allison had never imagined. And worse, she felt jealous. Jealous that someone else had touched Nova, held her, been close to her. That Nova was already building something new, something Allison could never be part of again.
Then came a blow that hit almost as hard as Nova walking in on her and Scott that day: Nova left. No goodbye. No text. Nothing. Allison found out from Scott, who had learned it from his mom, Melissa. Nova had packed up and left Beacon Hills. And worse? She didn't leave alone.
Lydia, Stiles, Isaac, Malia, Ethan, Aiden, even Derek? They all went with her.
It was a week later when Allison overheard her father talking with Melissa McCall and Nova's adoptive mom. Something about pregnancy. About Nova. About an unexpected complication.
Allison had stilled in the hallway.
"You think she'll keep the baby?" Chris Argent asked quietly.
"She already is," her adoptive mother answered. "She didn't tell them who the other parent is."
Allison felt like the ground disappeared under her.
Nova was pregnant.
From a one-night stand?
From someone she met in the woods?
Someone who wasn't her.
And Nova hadn't told them. Not even a message. Not even a look back.
Allison told herself she deserved the silence. That she deserved to be left behind. But that didn't make it easier to swallow.
Later, when word reached them from Mystic Falls from, Lydia, Issac or Stiles, Allison heard more.
That Nova had a new roommate.
And rumor had it, she was close to this roommate.
Very close.
Then came the slip from Isaac during a strained phone call.
"You know it's not just a one-night stand, right?" he said.
Allison's voice had gone tight. "What do you mean?"
Isaac had paused. Then sighed. "Nova's pregnant. Her roommate's the other parent. And it's... complicated."
Complicated.
It was always complicated with Nova. Even when things were tangled and messy, it was somehow still okay—because to Allison, Nova was worth it.
Allison sat on her bed that night, staring at her phone. Photos of her and Nova were still saved. Messages she couldn't delete.
She missed her.
But she couldn't undo what she'd done.
Nova had moved on. She had someone new—someone who wasn't Allison. She was building a future that no longer included her, a life that started from a single night but now held more meaning than anything they ever had together.
And maybe that was the hardest truth of all.
Nova was happy.
And Allison wasn't. Not even close. She was devastated—and maybe a little desperate. The idea that Nova had truly moved on, that she was building a life and family without her, clawed at something deep inside Allison. Nova had been everything to her. She didn't know why she ever turned to Scott, but she did know one thing now: she wanted Nova back. No matter what it took.
