Carry On, Wayward Sons [Harry Potter's Brother Reader]

Fluffy...

As Harry and his friends were on their way back from the trophy room the stairs moved of their own accord, and the three students found themselves going through the first door the found, hoping to avoid the stairs moving again, as they looked around they found themselves in a dark, dank corridor.

"Does anybody feel like we shouldn't be here?" Ron asked as Harry hummed in agreement.

"That's because we're not supposed to be here, this is the third floor. It's forbidden." Hermione said when suddenly a brazier lit up and they heard Filches cat Mrs Norris come in behind them.

"Run, now." Harry said as he took point, sprinting in the opposite direction of the cat.

"Quick, let's hide through that door." Harry said as they ran to it, he and Ron tried opening it but it was looked, Hermione moved them out of the way and used 'Alohomora' to unlock the door. They burst through the door and closed it behind them, Hermione was peeking through the keyhole until Filch left.

"He's gone." Hermione said as she stepped away to join Harry and Ron.

"Probably thinks it's locked." Ron remarked.

"It was locked." Hermione corrected.

"And for a good reason." Harry finished, they all looked at t a giant three headed dog as it woke up, Harry, Ron, and Hermione all screamed as they ran for the door. When they got back to the common room They were talking about what they had just witnessed, mostly focusing on why there was a three headed dog there.

"What do they think they're doing? Keeping a think like that locked up in a school?" Ron said as Harry was trying to wrap his head around it all.

"You don't use your eyes do you? Didn't you see what it was standing on?" Hermione said as Harry stayed out of the inevitable argument that Ron was going to make out of the statement.

"I wasn't looking at it's feet! I was a bit preoccupied with it's heads. Or maybe you didn't notice, there were three!" Ron said as they began walking up to the dorms.

"It was standing on a trap door, which means it wasn't there by accident. It's guarding something." Hermione deduced.

"Guarding something?" Harry asked his interest piqued.

"That's right. Now, if you two don't mind, I'm going to bed, before either of you come up another brilliant idea to get us killed, or worse, expelled." Hermione scolded them all before slamming the dorm door shut behind her.

"She needs to sort out her priorities." Ron remarked earning a nudge from Harry before they all headed off to bed.
