She makes it in peace

As Hermione reached the bottom of Gryffindor Tower, she looked around, warily. The hallway seemed entirely empty, so she darted the rest of the way to the girls' bathroom. Since it had been closed down since long before Hermione arrived at Hogwarts, there wasn't ever anyone there. Luckily for Hermione, this held out.

She creaked open the doorway and stepped into the cold, dark bathroom. As she started to look around the bathroom, she suddenly heard a click and saw a flash of light. She turned to see Colin Creevey sitting on a counter, with his camera pointed right at her. She immediately went to cover herself up.

"Colin? What the bloody hell are you doing in a girls' bathroom?"
"Me? I could ask you the same question!"
"But I'm a girl! I'm allowed to be here." Hermione stamped her foot, which only served to remind her of how cold the floor was.

"That may be, but why would you be walking into the bathroom naked?"
Hermione paused for a moment. This was a difficult question to answer. "That's none of your business!"

"Well, fine then." Colin took another picture. "If you won't explain yourself, then I've got no reason to explain myself."
"Stop being childish!" Hermione yelled. In her anger, she let her arms down as Colin swiftly took the opportunity for another picture. "I'll smash that thing!"

Hermione decided to ignore Colin and hope to get her clothes back. She turned and opened the nearest stall door, finding nothing inside. Colin, of course, took the opportunity to snap a picture of Hermione's butt.

Hermione sighed. "If you must know, my clothes were stolen. I suspect they may be here."

"Oh." Said Colin, putting down his camera. "And here I thought you were just a freaky streaker who wanted to be seen."
"No I don't want to be seen!" Hermione turned to face Colin, forgetting to cover herself again as she got worked up. "If I wanted to be seen, I'd probably be walking into a boys' bathroom, not a disused girls' one."
Colin thought on this for a moment. "Do you think about that sort of thing a lot?"
"NO!"

Hermione walked to the second stall and opened it, again finding nothing inside.

"So why are you here?"

"I wanted to make a photographic catalogue of the ghosts of Hogwarts!" Colin beamed. "I heard that a ghost called Moaning Myrtle hangs out here. Do you know about her?"

Hermione blushed furiously. "I ran into her in the Prefects' bathroom, and after she left I noticed my clothes were gone." She opened the third stall to again find nothing. "I think she's the one who took them, so I'm searching here for them."
"What were you doing in the Prefects' bathroom?"
"Bathing."
"But you're not a Prefect."

Hermione paused.

"That's against the rules," Colin continued "isn't it?"

Hermione stalked up to him, getting her boobs right up in his face. "Everyone breaks the rules sometimes. You're breaking the rules by being here!"

"Yeah, but I'm not a stickler for the rules like you."

Hermione turned away harshly, blushing even harder at the idea of herself as a rulebreaker. She walked up to the last bathroom stall, and opened it...
