Audrey Montgomery, Aria and Mike’s twenty-one-year-old older sister, returns to Rosewood after spending the past year living in Philly while her family lived in Iceland. This story is an AU where the liars are 18 years old and in college. A junior literary editor and lifelong book lover, Audrey is confident, caring, and fiercely loyal. She also returns with Ezra Fitz, her twenty-four-year-old boyfriend of nearly a year, whom she met while living in Philadelphia; they now rent a modest three-bedroom house in Rosewood together. Audrey skipped a grade being around the older generation of Jason Meredith etc. Audrey has already told her father about Ezra, and the family meets him shortly. Ezra works at college and the night before his first day back to work, Audrey and Ezra stop at a bar together for a quiet drink, only for Aria to unknowingly approach Ezra and flirt with him while Audrey is in the bathroom. Audrey’s return leaves Aria horrified when she discovers the attractive stranger is her sister’s boyfriend—and even worse, her new professor. Unlike canon, nothing happens between Aria and Ezra; Audrey drives Aria home with Ezra. Ezra has already informed college administration about his relationship with Audrey, and another professor grades Aria’s work to avoid any conflict. Audrey remains outside the Liars and never receives A’s messages, allowing her to maintain her own life while occasionally becoming involved when A threatens Aria with Audrey’s secrets. Those secrets include Audrey’s bisexuality, her past relationship with Jason DiLaurentis, her difficult party experiences involving Jason’s friends, and the fact that she knew about Byron’s affair before the family left for Iceland because she believed he had told Ella. As Audrey settles back into Rosewood, she reconnects with her original friends, works partly from home and occasionally in Philadelphia, spends evenings with Ezra, and becomes involved in her family’s struggles as Byron’s affair is finally exposed. She remains protective of Aria, eventually becoming almost a big-sister figure to the liars, while Aria develops age-appropriate relationships of her own, including Noel and other potential love interests. The canon mystery still unfolds around Alison’s disappearance and A, but Audrey’s presence changes the Montgomery family’s relationships, removes Ezra as Aria’s love interest, and gives the story an entirely different path.

Chapter 6: Aria's Plea and a Secret Shared

The oak tree in Rosewood Park was ancient, its trunk thick and twisted like a rope. Audrey slid onto the sun-warmed bench beneath it, the weathered wood smooth under her palms. She’d been here five minutes, watching a guy across the lawn futilely chasing his runaway dog, when she saw Aria hurrying down the path.

Her sister moved with a jittery urgency, her head swiveling as if checking for tails. She collapsed onto the bench, breathing a little too fast.

“You okay?” Audrey asked, keeping her voice low.

“Yeah. No. I don’t know.” Aria picked at a loose thread on her jeans. The late afternoon light dappled her face, making her look even younger. “Did you… when you were hanging out with Jason and everyone, before Ali went missing… did Garrett Reynolds ever seem off to you?”

The name landed like a stone in water. Ripples of old, bad memories spread out. “Garrett? Yeah, Aria. He seemed off. Everyone knew he had a thing for Alison. It was gross. He was way too old to be staring at a bunch of high school girls the way he did.” Audrey turned on the bench to face her. “Why?”

“No reason. Just… something Spencer said.” Aria’s eyes stayed fixed on the distant swing set.

“What did Spencer say?”

“Nothing concrete. Just rumors. About him and Jenna. And maybe… Ali.” Aria finally looked at her, her gaze sharp and fearful. “Did you ever see anything? Anything real?”

Audrey’s mind flickered back. Parties at the Hastings lake house. The dense, humid darkness of the woods. Garrett’s laugh, always a beat too loud. The way Alison would sometimes go quiet when he entered a room, a calculated stillness that was more alarming than any complaint. “I saw enough to know he’s not a good guy. If Spencer’s digging into him, she should be careful. You all should.”

“It’s probably nothing,” Aria muttered, retreating instantly. The wall went up. “Forget I asked.”

“I won’t forget.” Audrey put a hand on Aria’s arm, stopping her nervous picking. “Look at me. Is something happening? Are you guys in some kind of trouble?”

“No. It’s just… with everything with Dad, it feels like the world is off-balance. You start thinking about old stuff. That’s all.” The lie was transparent, a cheap curtain blowing in the wind. Aria had never been a good liar.

Audrey held her gaze for a long moment, the hum of a distant lawnmower the only sound between them. She could press. She could demand. But she knew that look—the trapped-animal panic just beneath the surface. Pushing now would only make Aria bolt.

“Okay,” Audrey said softly, letting go. “Okay. But listen to me. Whatever ‘old stuff’ you’re thinking about, you steer clear of Garrett Reynolds. That’s not a rumor. That’s advice from someone who was there. And if you ever feel like you can’t talk to Mom or Dad… my door is always open. Our house is a no-questions-asked safe space. Anytime. For any reason.”

Aria’s shoulders slumped with something like relief. The fear didn’t leave her eyes, but the frantic edge softened. “Thanks, Aud.”

“Always.”

They sat for a few more minutes in the fading gold of the afternoon, not talking, just being sisters on a bench. Then Aria’s phone buzzed, and she flinched, staring at the screen like it was a live wire. “I gotta go. Hannah’s mom is picking me up.”

“Call me later,” Audrey said. Aria just nodded, already walking away, her thin frame disappearing between the trees.

Audrey stayed on the bench until the sun dipped below the roofline of the community center, casting the park in long, cool shadows. Something was going on. It was in Aria’s twitchy hands, in the specific, ominous name she’d pulled from the past. It felt bigger than their dad’s affair. It felt… familiar. The same poisonous unease that had seeped into the town after Alison vanished was back, and it was clinging to her sister.

She drove home, the knot in her stomach tightening.

Ezra was grading papers at the kitchen table, red pen in hand. “How’d it go?”

“She’s hiding something,” Audrey said, dropping her bag on the counter. “She was asking about Garrett Reynolds. From back in the day.”

Ezra looked up, his expression grim. He knew the history. “That’s not good.”

“No, it’s not.” She opened the fridge, stared at its contents without seeing them, and shut it again. “I offered her a safe place here if she needs it. I don’t know what else to do.”

“That’s all you can do,” he said, his voice steadying her. “You can’t force her to tell you.”

The week settled into an uneasy rhythm. Audrey worked from her home office, editing a sprawling manuscript about a 19th-century whaling voyage, the words blurring as her mind circled back to Aria. She called her mom every other day, checking in.

It was during one of those calls, on Thursday evening, that Ella’s voice cracked.

“I got a letter today,” she said, the words thin and frayed.

“From Dad?” Audrey asked, leaning back in her desk chair.

“No. It was anonymous. Typed. It said… it said, ‘He’s still lying. The motel wasn’t the only place. Ask him about the conservancy fund.’” A sharp, ragged inhale. “It was signed with just… a single ‘A.’”

Ice water trickled down Audrey’s spine. “What did Dad say?”

“He denied it. Said it was a sick joke from someone at the college trying to ruin him. But his face, Audrey… he turned gray.” Ella’s voice dropped to a whisper. “Who would send that? Who knows these things?”

“I don’t know, Mom.” Audrey’s mind raced. An anonymous ‘A’. It was too theatrical, too cruel. It wasn’t the spam text she’d deleted; this was tangible, deliberate, aimed at the wound in her family and poured salt directly into it. This ‘A’ wasn’t threatening her, not directly. They were dismantling her parents. “Do you have the letter?”

“I burned it in the sink. I couldn’t stand to look at it.”

Audrey closed her eyes. “Okay. Okay, just… try to breathe. We’ll figure this out.”

But after she hung up, she didn’t move. She sat in the quiet of her office, the only light from her desk lamp. Someone was doing this. Someone knew about the motel, and possibly more. It was targeted harassment. It had to be connected to Meredith, or some enemy of her father’s from the college. It was rational, explainable. It had to be.

She didn’t tell Ezra about the ‘A’. Saying it aloud felt like giving it power, like inviting it across her threshold. Instead, she buried herself in work and in the small, normal rituals of her life. She made dinner. She did laundry. She read manuscripts until her eyes burned.

On Saturday, she drove to her parents’ house on a pretext of returning a book she’d borrowed. She really just wanted to see Aria.

Byron was nowhere to be seen. Ella was in the garden, pruning roses with a fierce, concentrated energy. Aria was in her room, painting her nails a dark, shimmery blue.

“Hey,” Audrey said, leaning in the doorway. “Just wanted to see your face.”

Aria smiled, but it didn’t reach her eyes. She looked tired. “I’m okay.”

“Still a safe space. Always,” Audrey said, her tone light but her meaning heavy.

“I know.” Aria blew on her nails. “Thanks, Aud.”

The visit was brief, a snapshot of a family holding its breath. As Audrey walked back to her car, she glanced up at the house. For a second, she thought she saw a flicker of movement at Aria’s window—a shadow against the curtain, looking down. Then it was gone.

She drove away, the familiar streets of Rosewood passing in a blur. The fear was no longer a quiet hum in the background. It was a distinct pulse, a second heartbeat. Someone was watching her family. Someone was cutting them, one careful slice at a time. And the worst part was, she had no idea who they were, or when they might decide to cut deeper.
