This is just a random oneshot type thing I thought up when I was bored.
Luna Lovegood burst into the room with a huge grin on her face.
"Luna Lovegood, what is that gigantic grin all about?" Hermione said, frowning.
"Oh my god! You'd never guess what!"
"Let me guess, your shoes were stolen?" Hermione said.
"No, fi-"
"There was pudding?"Ron asked, hopeful.
"No Mcg-"
"Voldemort's on the move?" Harry whispered.
"No, well that too, but Filch is dating McGonagall!"
"WHAT?! Chorused the dumbstruck students. Luna looked from shocked face to shocked face.
"The tunnels?" Ginny asked.
"Yes, the tunnels are so useful!" The other students looked at Ginny and Luna confused.
"Well, basically," Ginny started, "We found these secret tunnels near the potions rooms. Luna went down them while I distracted the teachers and that's how she saw them.
"Yes," Luna continued, "They were in his office, I saw them! They were kissing and then his hands were in her-"
"I think that's enough, Luna" Hermione interrupted before Luna could go any further.
"Show us!" Ron shouted. Ginny looked at him and smiled.
"Yeah, Luna let's show them! Oh gosh Ron you'll love it!" She said, excited. She looked at harry, he nodded in agreement. Luna and Ginny led the way to the Potions corridor, but instead of walking straight to the classrooms, they turned and walked right towards the wall.
"Er, but Ginny, the wall-" Harry stopped talking as he saw that the wall overlapped rather than joined.
"Wow!" Ron mumbled. Hermione and Neville stood there stunned. They all walked through the gap and found themselves in a narrow corridor. It was not possible to walk abreast so they had to walk single file. Luna led the way, followed by Neville, Hermione, Ron, Ginny then Harry. They walked along the corridor and as they all set into casual conversation there a dull rumbling sound then what sounded like an entrance being shut off. They all stopped. Harry ran back and checked to see what had happened. The wall had slid into place so there was no opening at the entrance.
"Er guys!" The others came back and gasped when they saw.
"Great," said Hermione, "We're stuck"
Oh no, they're stuck in the tunnel!!!! No, what are they going to do?!
