AN: Louis and OC. I don't own anything that's not mine, namely anything by JK Rowling or Bruno Mars.
You can count on me like 1, 2, 3
I'll be there
Louis Weasley was keeping to himself in the library to catch up on some homework, when a girl sat down next to him.
"Oh Lou, I'm so glad I found you," Ravenclaw prefect, Eva Laurent whispered.
Louis smiled. "What can I do for you Eva?
"I'm not exactly sure. Well I found something out about Louis and Blair. I mean I caught them cheating on your cousins. Together."
"Wait what? Your brother and Blair. Cheating on Molly and James. Together?"
Eva nodded. "And it's been going on for months according to Louis. Apparently when he's on prefect duty he'll tell the other prefect to go off and patrol by themselves, that's when he meets Blair in a classroom and well I think you know can guess what happens then. Before you ask, no I haven't told James or Molly, nor have I told anyone else. They swore me to secrecy, but I can't do nothing. That's why I need your help. I need to figure out what to do."
"You can count on me. For one, whatever we do, we have to wait until after the Quidditch Cup. Quidditch is a priority for us Weasleys and if this came out, who knows what kind of taunts Slytherin would throw at us."
Eva nodded. "That's why I haven't told them yet."
Louis grinned. "You're beginning to think like a Weasley."
Eva smiled. "Well considering you're my best friend, and I'm friends with your cousins, it shouldn't be a big surprise that I've started thinking like a Weasley. But back on track, any ideas on what we do?"
"How about one night when you're doing your prefect rounds with Louis, tell him you'll look out for him and Blair and find out which classroom they're in. From there you go to Molly and James and tell them Peeves is destroying a classroom and he won't listen to you. We both know Peeves only listens to Molly and James. I'll make sure they're in the common room."
"That's not a bad idea. It's just what my brother and that tart deserve."
AN: Yes, I created an OC called Louis Laurent, in my headcanon Molly usually gets teased for dating someone with her cousin's name.
