Jaren decided to step in before Selena and Lee resorted to throwing cookies or pulling out their wands. He stood between both of them to stop them from yelling/doing anything else to each other.

"I don't think that's necessary," he said in a quiet, calm voice. "If you wish to discuss non-potions matters, you'd best do it outside this classroom." To Lee he added in a bare whisper so that only Lee and possibly Selena could hear, "You should be more careful of what you say in the Ministry's presence, even if you do disagree heatedly with anything about them. Fighting back physically is not always the best solution."

His intense deep green gaze seemed to bore into Lee's, telling him that if he had anything else to add to that, he had best leave it until after they had left the class to avoid further scenes.
