The smell of the potion had changed since she first smelt it in sixth year. Back then it had been freshly cut grass, new parchment and spearmint toothpaste and, though she'd never admit it, Ron's hair. However, that was a year ago? Twenty years to come? Time was a fickle and extremely confusing thing.

"Kitten," Sirius greeted by whispering in her ear as she packed her potions stuff away. "Want to tell me what you smelt in that lovely brew?"

"I thought I told everyone, Sirius," she sighed. "Fresh grass, parchment and toothpaste."

"You lied." She didn't make any move to look at him in shock, that would've been a big giveaway. She wished her heart had listened to her brain and tried to stay the same but her pulse raced with nerves. With his canine hearing, and with how close he was, there was no way he hadn't heard. "See? So, what did you really smell?"

"Sirius," she scoffed, hefting her bag onto her shoulder. "It had nothing to do with you."

"Oh, I know that," he confessed as they walked out of the classroom and into the hall. "I just thought it would be an easier conversation with me than the other canine that was in the room." Her heart thudded in her chest, her pulse racing even more and Sirius' smirk seemed to grow. "I knew it."

"Does it matter?" Hermione questioned, stopping to face the Gryffindor and sighing with annoyance. "It's my business."

"Remus smelt vanilla, old books and chocolate." Hermione blinked, trying to piece it together and what it had to do with her. "You're unbelievable," he huffed, rolling his eyes. "Your perfume smells like vanilla, you're almost always in the library where there are old books and he adores chocolate. You're a two out of three!"

"I'm sure I'm not the only one who visits the library and has a vanilla scented perfume."

"You're the only one he cares about," Sirius countered. "So, we all know that you smelt him in that potion, why won't the two of you get your head out of your arses and be done with it?"

"It's just a potion," Hermione told him, tightening her grip on her bag.

"A love potion!" Sirius exclaimed, waving his arms around. "It's a potion that is all about love! You love him. He loves you. Love!"

"Are you trying to play Cupid, Sirius?"

"Is that so bad?"

"Yes. Yes, it really is."
