Lily is in her fourth year in this chapter while Albus and Scorpius are both in their sixth year. It's a bit vague in this one shot.

Prompt: "Notify"

The whole thing started when Wren Frost walked over to the Hufflepuff table to hand Lily Potter a letter. "Miss Lily," she began, holding the slender envelope out to her, "can I ask a favor of you?"

Lily twitched but tried to be patient with the Slytherin student. "You really don't have to keep calling me 'Miss' all the time, Wren."

Wren's lips tugged up just the tiniest bit which Lily took to mean she was amused. "All the same, can I ask a favor?"

"Alright, what do you need?" she asked, scooting over to allow her friend to sit down.

"Can you give this to your brother?" she asked, offering her the envelope.

Lily's eyebrows went up. "You want me to give him a letter?" She accepted the envelope anyway. "Is it a love letter or—oh, wait, which brother do you mean?"

"Albus. And I don't know what it is—one of the fifth year girls wanted me to ask you to give it to him."

Lily couldn't help but stare. "One of the fifth years? Which one?"

"Menthe Greengrass. She's Daphne Greengrass' daughter from her first marriage, but after she divorced, she and her daughter returned to her maiden name. She's also the cousin of Scorpius Malfoy, since his mother, Astoria, is Daphne's younger sister. She is also related to-" Wren prattled off, ticking off each point on her fingers.

"Wren," Lily interrupted. "Um, were you studying Dynasties of Pureblood Families again?"

Wren blinked. "Of course."

"It, ah, shows," Lily coughed before examining the envelope again. "I wonder what she'd want to tell Al…"

Wren shrugged.

"Well, I guess it can't hurt, right?" Lily smiled brightly. "Alright, tell her I'll do it."

When Lily handed her brother the letter, he looked just as confused as she had. "What would Menthe Greengrass want with me?" he asked, brow furrowed as he opened the letter. Lily waited quietly as he skimmed the letter; she decided that it couldn't have been a love letter, since he wasn't blushing in the least when finally finished reading it.

"What'd she want?"

"Huh?" he asked, looking at her in surprise. Obviously, he'd forgotten she was there; she pouted. "Oh, she was saying thanks—she's in my Potions class and we got partnered last week. Funny, she waited so long to say—and in a letter at that."

"I thought she was a fifth year student."

"She is, she's just really good at potions—they put her into the next higher class in her first year, I think."

She watched as he tapped the letter against his chin, absently musing about the mystery. "Are you going to write her back?"

"Mmm?"

"Are you. Going to. Write. Her back?" she asked, punctuating her question with pauses.

He blinked. "Oh, I suppose I should—if I write one later will you give it to her?"

Lily frowned. "Why can't you just give it to her?"

"Not as much fun—besides, she's kinda shy. I'd embarrass her too much, just waltzing up and handing her a letter. How 'bout it?"

Lily sighed. "Oh, alright—hurry and write it then. I'll give it to Wren and she can give it to her."

And so it began, Lily found herself trafficking letters back and forth from her brother and Menthe. It kept up for several weeks, the two of them writing a reply every other day. The constant run around would have worn Lily's patience thin, if it weren't for the fact that she had managed to weasel out of her brother that the letters weren't just any notes—apparently, somewhere down the line, they'd become love letters. Then the whole affair was just too amusing, (and dare she say romantic?), to stop.

There was one small problem though—one day, Lily had a letter from Albus but when Lily walked into the Great Hall, she found Wren missing. She walked over to the Slytherin table to ask Wren's roommates about her friend. She finally dragged the truth from the reluctant girls—Wren had the flu and was holed up in the Hospital Wing.

She forgot all about Albus, Menthe, and even breakfast as she ran to the Hospital Wing to check on her friend. Madame Pompfrey, however, refused to let her get too close to her contagious friend. After a bit of talking, Lily had to hurry to her first class. About a half hour into the history lesson, she remembered the letter. She forgot to pay any attention to Professor Binns as she tried to think of what to do with the letter.

It'll take a few days for Wren to get better…what do I do with it until then? She could try and walk up to Menthe and give it her later, she supposed but then she wasn't precisely sure who Menthe was. Maybe she could ask one of the Slytherins to point her out…or maybe even give her the letter.

That was when one of Lily's more spectacularly foolish ideas hit.

Later that night at dinner, Lily stood by the door and waited as students filed into the Great Hall until she saw the person she had been looking for finally show up. Before he had a chance to step into the Hall, Lily firmly planted herself in the path of Scorpius Malfoy.

The pale haired Slytherin looked down at her in confusion. "What do you want…?"

"Lily. Lily Potter," she provided.

His snorted disdainfully. "I should have known. Alright, what is it?"

"Your cousin is Menthe Greengrass, right?"

Now he frowned warily. "Yes…?"

She presented him the letter. "This letter is for her; could you point her out to me?"

"Why?"

Patiently, she raised her brows at him. "So I can give it to her, of course."

He glared at her and her suspiciously bland tone. "Like I would trust a Potter giving my cousin anything—give it here. What is it anyway?"

"Just a letter," she answered and held it up for him to look at. Like she was actually going to hand it over. After all the grief he gave her brothers, she didn't trust him that much. (Or maybe it was just James…her eldest brother had a specialty for getting under people's skin.) "Now, where is she—hey, give that back!"

He snatched the letter from her, flipping it over in his hands above his head so she couldn't reach it. "I don't see anything wrong with it…" he glanced imperiously back down at her. "That doesn't mean that there isn't though."

"Hey, c'mon, she's expecting that," she insisted. Kicking him in the shins or hexing him sounded promising, but then if she got caught, her house could lose their points. She tried to think of something to do to get the letter back.

"She is, huh?" He looked at the letter considering it, and then walked quickly into the Great Hall, letter still held aloft in the air. Lily blanched and took off after him—thankfully, none of her brothers or her older cousins were there yet, although she had to wave to Hugo to sit back down when he spotted her. She tried to look calm as she hurried after the Malfoy heir as he marched over to his house's table, straight up to whom she presumed was Menthe herself. Menthe was a slim, pretty thing with dark hair and wide blue eyes—wide, Lily guessed, because her older cousin and her boyfriend's younger sister walked up to her. "Menthe, letter for you."

"Ah, thank you, Scorpius," she answered in a quiet voice.

Scorpius nodded and turned around only to blink down at Lily as if surprised she had followed. "Now, what?"

She looked up at him at a loss. "I, uh…thank you?"

"Whatever," he answered dismissively then walked around her to join some boys she presumed to be his friends.

She quickly left to join her own table, rather than hover next to the shy Menthe. She waved to her brothers as they came in but hurried over to her table, ignoring their invitation to her to join them. Throughout dinner, she couldn't help but glance up at Scorpius and Menthe every now and then.

The next day, as she tried to enter the Great Hall, she was surprised to find Scorpius waiting for her at the door, much like she had for him the night before. He presented her a letter. "From Menthe—just what are you two writing to each other for?" he asked so quickly she had to blink at him.

She reached for the letter but he jerked it away from her. "It's private," she answered, relying on a half-truth; Menthe may not have been writing to her, but what she wrote to her brother was private (no matter how much she wanted to peek at the letters). "Give it to me."

Scorpius rolled his eyes and tossed it to her before turning and entering the Great Hall. She glared after him and entered behind him.

Over the next few days, a new ritual formed—whenever Lily tried to hand Menthe the letters directly, Scorpius appeared from nowhere to take them from her and give it to his cousin himself; whenever Menthe finished a letter, Scorpius delivered the letter himself. Even when Wren returned from being ill, Scorpius kept a constant vigil for the letters. Lily would have found it rather annoying if it weren't the fact she couldn't help but giggle at his over-protectiveness to his cousin. It reminded her of James overprotective nature to her, Albus, and their cousins. That and she found herself looking forward to talking to Scorpius himself—he actually began to chat with her in between asking questions about what the letters were about.

It was getting near to summer when Lily walked up with a letter to him, having giving up trying to avoid him. "Here," she said, handing him the note.

He looked up at her curiously for a moment before accepting it; it wasn't breakfast or dinner, like it was when she usually gave him the letters. "Fine—I'll give it to Menthe in a bit then," he replied distractedly—she had interrupted him in the middle of an Arithmancy problem.

"It isn't for Menthe," she explained tightly.

He blinked and looked up at her. "What?"

"It's for you," she answered then turned on her heel and left.

He watched her blankly as she marched off before tearing the envelope open. He was disappointed to see only a small scrap of parchment inside, he had half hoped she was going to explain just what it was she had been writing to his cousin for. Brushing aside his disappointment, he held the paper up and read. Then stared.

My brother's dating your cousin.

--Lily

P.S.—I like you.

He flipped the paper over, hoping that maybe there was some sort of explanation.

Yes, I do mean like in that way.

Flabbergasted, he stood up, accidently dumping his books and parchment to the ground. He hastily swept his mess up into his book bag and took off after her. He rushed to catch up with her and finally managed to after she entered the library. She looked expectantly at him with the faintest dusting of a blush across her freckled cheeks as he sat across from her at her table. He looked dumbfound for a moment before opening his mouth, but then abruptly closed it and stared. Then, without a word, he pulled open his bag and began to rummage around in it before he tore of a piece of his parchment from his homework, (he'd have to start over now), and jotted down a note before he shoved it to her.

She read it nervously.

I like you back.

But don't you dare tell anyone.

She glanced up at him.

"Especially your brothers," he warned her.

She smiled.
