Blood starting to run in his legs again, when George moved to sit somewhere that wasn't on top of them, Fred nodded to his brother's words, pressing his left palm over one of his eyes, brows still furrowed. They really needed to stop acting so passive, it wasn't like them at all. Passive in the face of oppression. "Just a sec. 'm thinkin'," the boy muttered to himself when George asked if he had a plan, face turning slightly vacant. It usually went like so, Fred coming up with the the general idea - the beginning, the start of something big and brilliant and great, and then George thinking out how they were actually going to manage to pull it off. This time it wasn't about some grand old prank, though. This time it was going to be something that honest to Merlin mattered.
Things that mattered did not seem to be any more difficult to come up with than pranks, Fred noticed after a couple minutes of dwelling inside his head, but he wanted them to do something that would really, really counted. Something big. Something important. Something ---... But of course!
"Muggleborns," he said after nearly three minutes of unnatural quietness, lifting his eyes to George with a near-wicked grin, anger washed away in the face of the sheer, sudden excitement he felt.
