1. Neville's Night Adventure

I need a place to sleep.

Neville Longbottom had once again forgotten the password to the Gryffindor common room. His memory was generally better than when he was a first-year, but such things still happened. And after that incident with Sirius Black two years previously he knew better than to write any passwords down. And so he was stranded in the corridor in the middle of the night (he had sneaked into one of the greenhouses earlier that evening and just lost track of time) and he had nowhere to sleep. Unless…

It was not far from the Gryffindor Tower to the Room of Requirement and he fortunately didn't meet any teacher (or Peeves) on the way. He walked past the stretch of blank wall three times and opened the door that appeared out of thin air. The Room turned into a small but cosy bedroom with a big double bed standing in the middle. The sheets were white and soft like marshmallows and there was a pair of blue pyjamas lying neatly folded on the pillow. Neville quickly put them on and slipped under the covers. The bed was unbelievably comfortable and he was beginning to feel glad that he had forgot the password.

He was already half-asleep when he heard the door creak and open. He lunged madly for his wand which was still in the pocket of his robes. He blinked several times and then strained his eyes to see who (or what) was coming. The room was dark but there was a little light coming from the corridor through the open door and he could just make out a person in a short yellow nightgown and fluffy slippers. Her blonde hair was falling on her shoulders in a messy way and her eyes seemed to be closed. Luna.

She closed the door slowly behind her and came up to the other side of the bed. Before Neville could react, she slipped in beside him and went to sleep (or continued sleeping, he wasn't sure). He smelt a faint scent of lavender…

Neville was at a loss what to do. It was such an unexpected turn of events that he couldn't even think straight. But after a couple of minutes his head cleared a little. Well, he couldn't stay there, that was sure. He would have to sleep in the corridor after all.

He took his clothes (he couldn't risk changing when she could wake up any minute) and made his way out of the Room as quietly as he could. When the door closed behind him he heaved a sigh of relief and immediately after that a sigh of pity. That bed was really comfy…

"Mr Longbottom," came a shrill voice from behind him and he jumped up in surprise, "what do you think you're doing out of bed in the middle of the night? Thousand points from Gryffindor!"

"No, Professor, please!" he answered in horror, turning around to face her. But the corridor was empty. He frowned and looked around carefully but he was definitely alone. That is, until Ron Weasley's red head appeared floating in mid-air.

"Ha ha, gotcha, Neville!" he laughed. "You should have seen your face!"

"What are you doing here?" he asked, trying to change the subject.

"Well, I have a better question." Harry Potter's head appeared beside Ron's. "What are you doing here?"

They both looked at him curiously and he realized he was standing there wearing pyjamas and that his clothes were bundled in his arms. He flushed a little and tried to think of a good explanation but at that moment they heard a door creak open. Luna came out of the Room and sleepwalked right past them humming a happy tune. Harry and Ron were speechless for a minute and just gaped at Neville and at Luna's retreating back. The Cloak slipped to the floor revealing Hermione who looked as dumbstruck as the other two.

"What– Why– Neville?" She looked at him in amazement.

"Merlin's pants!" Ron finally found his voice. "I didn't know that you and Luna were– Wow, mate, it's just…"

"It's not what you're thinking," Neville protested feebly but he could feel his face was getting tomato red which definitely wasn't helping.

"Hey, I'm sure there is some other, innocent explanation besides the obvious one," Harry joked, though he still looked a little shaken.

Neville felt anger rising inside him. He was tired and he just wanted to go back to sleep. He wasn't in the mood for this.

"You know what? You can think what you want. But it was a coincidence. You can ask Luna tomorrow. Nothing happened. I didn't even know she would come here. Now tell me the password to our common room, will you?"

"Carpe diem, Neville. The password's carpe diem," said Ron smirking and the three of them vanished beneath the Cloak.

It wasn't the first time Neville wished he knew how to cast the Obliviate spell.
