"Excellent work Mr. Poe." Morgan said smiling, as he watched Arthur deftly extract the poison from the plant. "5 points to Gryffindor for a flawless performance. And another 5 for answering my question. Yes, it can be used as a poison" He glanced over at Scorpius. "Well Mr. Malfoy, I suppose that's up to you, isn't it? There are a variety of ways, some less effective than others...I suppose you could always try asking politely?" he said, grinning slightly. He then turned to Daisy. "Ah, Ms. Lambert. 5 points to Gryffindor for attendance, and another 5 for the question. Yes, they are quite useful in joke products. Oh, and another 5 for the poison." Finally he turned to Mariana. "Well...alright. Ms. Diggory, I suppose you deserve something for showing some initiative. 5 points to Hufflepuff, and if you'll just extend that hand..." He raised his wand and touched it to Mariana's burned hand. There was a sucking sound and the inflamed area lessened a little, but didn't completely disappear. "That's the best I can do for now, you might want to check with the nurse after class is over. But you're in no immediate danger."
