Harry was happily eating some sheprds pie when Hermione tapped him on his shoulder.
"Harry, I think we should try this out for the next meeting. It could be really useful, what do you think?" She said pulling Harry closer so he could see the book better. She looked up at Ron who was watching and gave a thumbs up, then looked back down once more as Harry started to comment on the Alarte ascendare charm.

Flashback

"Okay I'm not sure if you guys noticed but Harry has been really stressed lately," Hermione paused as she looked between the Gryffindor twins, still unsure which was which. "Ron and I have been trying to think up ways to cheer him up and get him to have a little fun. At first we thought of little things like Quidditch, then there was the ban. We also thought exploring the castle, but being followed around by Flich ..."
Hermione let her sentence drop knowing how they were his favorite to follow.
"We wanted you to help us think of something." Ron said as he scribbled down a couple more notes from Hermione's potion homework. A few seconds passed before the twins exploded with ideas.
"Well we did just finish-"
"A new potion, although-"
"It's not perfect yet-"
"We still have a few-"
"Bugs to work out."
"We call it-"
"LOVE THY ENEMY!" The twins said together after leapfrogging off of each others sentences.
"Okay what does it do?" Hermione asked warily. The name didn't sound all that appealing to her, especially not when her friend had the biggest enemy on his heels. She still felt like asking the twins was a bad idea but, they were the best at pranks and cheering people up.
The twins shook there heads and started talking amongst themselves, ignoring Hermione's question.
"Do you think it's wise, brother of mine to give him that one?"
"Well why ever not he has so many."
"Let's see there's Snape,"
"Umbridge and all of Slytherin."
"A couple Ravenclaws too."
"Let's not forget Tom."
"Tom! The innkeeper! What did he do to get him as an enemy." Ron joined in abandoning his essay.
"GUYS!" Hermione snapped.
"GIRL!" they snapped back. Hermione just continued to stare at them until Ron reluctantly went back to his essay.
"Fine" Fred sighed.
"You know we could try heartswish."
"Don't be silly brother we haven't finished testing it"
"True, true but we did just gain two volunteers"

Flashback end

Ron looks around quickly to make sure no one was looking. When he thought no one was paying attention he took out a sparkling blue vile that seemed to turn gold as the light reflected off of it, and pour it into Harry's pumpkin juice. He didn't notice professor Snape watching.
Snape wondered for a moment before brushing it off. He was a Weasely after all, the brat was probably taking after his brothers. They were just playing pranks on each other like Potter's father use to do with his friends. Professor Snape went back to his food and waited for the results. Maybe he can take some points off of the Potter brat for making a scene.
Professor Umbridge was thinking along the same lines, but on a more grander scale.
