Hermione swayed, all the while cursing the Weasley Twins' newest invention - which they'd slipped her and the boys over dinner. Mimicking a mixture of drunkenness and the visions caused by Muggle drugs, it certainly wasn't something she'd ever take willingly.

The room swirled and blurred, flashing different colors and patterns. Ooh! And the walls were moving! Had the ceiling always been that garish shade of yellow?

It was so bright and radiant that she could see where she was going–

Until she slammed into a wall of black.

"What do you think you are doing, Miss Granger?" Snape hissed, grabbing her arms to prevent her from falling arse over teakettle.

She blinked. "Hello, Professor," she greeted, then paused. "Did you know I always thought you were quite handsome?"

He froze in shock for half-a-second, then growled, fishing a vial of something from his pocket, and then pressing that vial into her hands. "Get some sleep until it wears off, Granger. You're clearly delusional."

She protested, crossing her arms. And as she did, Professor Snape's nose seemed to grow larger and larger until she could just touch it.

Boop!

No, there was only air there. She stared at the finger who'd done her dirty like that. She'd wanted to boop the nose!

"What...are you doing?" Snape asked, his voice strained.

She stared up, and he was much closer than she had initially believed. So close, in fact, that it was very easy to grab his collar and boop the nose.

Success!

She let go of him and scrambled away, because the Professor looked angry.

Oh, dear Merlin, she hoped her finger hadn't bitten the nose.

"Yes, Professor?" she asked sweetly, batting her eyelashes an excessive amount. She hoped that seeing her eyelashes distracted him from being angry. They were certainly distracting her.

His fist clenched and then unclenched at his side, like a Muggle claw machine. He sighed tiredly. "Just...drink that and go to sleep."

Did the eyelashes distract him? It seemed to have worked. She resolved to follow his instructions, but continue blinking furiously just in case.

"Night, night, Professor," she declared, chugging down the potion.

Snape was just about to leave the room when she called out to stop him. "I shan't go upstairs until you say night-night to me, Professor."

He seemed strangely reluctant to do so, and she smiled encouragingly.

"Come on," she instructed. "After me. Night-night, Professor," she said slowly, gesturing for him to say it back.

"...Night, night...Granger."

She clapped. He was very good!
