A/N: Not much to say, except enjoy and review.

Hermione and Jacqueline rushed out in worry in order to find the whole Common Room laughing. Both girls were mad, not knowing yet what happened. The two went over to Ron and Harry who were laughing, while clutching a small cardboard box.

"Ron, Harry, what is going on?" came the shrill voice of Hermione, while Jacqueline analyzed the situation. Ron and Harry couldn't answer. Hermione looked helplessly at Jacqueline and said, "Not you too." Jacqueline was sitting in an armchair by now, laughing along. Hermione stood there, paralyzed at the sight in front of her. When all calmed, Ron, Harry, and Jacqueline tried to explain that the sound of the explosion was just a new product of Fred and George's.

"It's called The Atomic Bomb. They stole the idea from the Muggles. Something having to with a war," said Ron.

Hermione took the thing from him and said angrily, "Ronald, that is not funny. You scared me to death with that thing."

And she stormed out of the room.

Ron then mumbled something about not being able to take a joke.

"What happened anyway?" asked Jacqueline with a laugh.

"We were tasting some invisibility candies, when someone threw one of the Atomic Bombs. The rest you know," said Ron.

"Is Hermione always like this?" asked Jacqui.

Both boys nodded.

"Too bad. She needs to learn that breaking a school rule isn't always bad."

The guys nodded again. Then, Professor McGonagall rushed in.

"Is everyone ok? I heard an explosion," she gasped.

The room went silent. McGonagall scanned the room and saw Ron with a red face and Harry just standing there. Behind them sat Jacqueline with a thoughtful expression on her face.

"You three," said the Professor, "Mr. Potter, Mr. Weasley, Ms. Mireille, please follow me."

They got up solemnly and followed the Head of their House. When they arrived at McGonagall's office, she turned around and said sharply, "What in God's name went on in that room?"

The boys looked down, while Jacqueline looked steadily into McGonagall's eyes.

"Well, Mr. Potter, Mr. Weasley? Any comments?"

They didn't answer.

McGonagall looked at Jacqueline, scowling. "I think detention for all three shall be fit, since neither of you want to say anything."

Ron gaped at her while Harry looked on with bitterness.

Jacqueline looked at her comrades. She then spoke, "Please Professor, it wasn't their fault. It was mine."

All looked at her in wonder.

"I had the Weasley's Deluxe Box of Tricks and the Atomic Bomb just fell out by accident."

McGonagall looked at Jacqueline thinking if she should buy the story. Eventually she said, "Very well, Ms. Mireille. No detention for you boys. As for you, fifteen points from Gryffindor and a detention with me this Friday."

Jacqueline nodded silently and the three seventh years left the office.
