Hecate's eyes raised assessing the room while writing down her findings on her new potion. Greene and James were on one side, and Greingoth (the girl) and Lockhart were on the opposite side. The first two were first years... likely to set the place a blaze... the second couple she'd seen on the quidditch pitch... thankfully Greingoth was smart enough not to kill the boy in front of a professor. She summoned her bat Lucille and put it on her desk before her. She was going to have to keep an eye on all four.
