Regulus/Neville
Regulus had been watching James. He knew that this would set the tone for the future, grab people's trust and loyalty. Even the Dark Lord had used those methods before the curses had started, but James was better, at least for these people. The tone would have never worked with Slytherins.
He was pondering the differences when Longbottom came his way. "Aconite, by the kilos," he said. "I think that must be our first priority. Patrick was already stacking up for this full, but come next month, we will need plenty of it. I would suggest devoting at least half a greenhouse to it. I will provide you with a list of everything we need with approximate quantities. While we can play around with the rest, the aconite is of outmost importance."
