Harry stared blankly at the flagstones as they passed underfoot, biting his thumbnail.

Ron shifted over, bumping Harry with his shoulder, "You listening at all, mate?"

"Wha-?" Harry looked up guiltily, "Sorry, what were you saying?"

Ron shrugged, "Just chatting about charms. What's up with you then? You've been quiet since breakfast."

Harry sighed and admitted reluctantly, "I can't help thinking Draco's hiding something."

Hermione almost missed her stride, hopping a little to catch up, "I thought you and Malfoy were getting along?"

Harry grimaced, "I mean we were, technically still are, but he..."

"Just because a bloke has a suspicious ferrety face doesn't mean he's actually up to anything," Ron said. He yawned, stretching his arms over his head, "Sides, Malfoy is shit at being evil."

"I'm not saying he's up to something evil," Harry said.

"Just up to something," Hermione said raising her eyebrows.

Ron slung an arm over Harry's shoulder, "So build a case for it. It'll be good practice for when we're proper aurors."

"He always changes in the bathroom-"

"Nev did too," Ron interrupted, "Some people are just shy."

"I wasn't finished," Harry said, "He gets up early to do it, and at night he'll wait until he thinks I'm asleep to put on his pyjamas."

"My point still stands though," Ron said.

"He's got this bag and I'm positive it's got an undetectable extension charm on it but he's rigged it so only he can open it," Harry said.

Hermione gasped, "You went through his things!?"

"I only tried the bag, nothing else!" Harry said defensively.

Hermione glared at him, "That's no excuse!"

Ron grimaced, "Went a bit too far, mate."

"He acts suspicious!" Harry said stubbornly, "Of course I'm gonna suspect someone who acts like they're hiding something!"

"Harry. He's not dangerous so just leave it alone. Leave him alone." Hermione sighed, a worried pinch between her eyes, "Nothing is going to happen this year. You know?"

"I know," Harry muttered.

"Then stop looking," Hermione said.

Ron squeezed his shoulder, "It's gonna be alright from here on out, mate. You'll see. The last thing you need to worrying about is Malfoy."
