Before he went to help and put out the fire with the use of aguamenti, Dorian realised that the Hufflepuff girl named Maddie was talking to him and with his wand still pointed at the door he looked at her as she spoke.

And then his face fell as realization dawned on him as well. Had his plan been Professor Marchand's plan all along but had they blew it earlier? Was that why he had looked dissapointed?

He turned to the Charms Professor again his tears came back in his eyes. Not because he was scared again. He was already scared so he couldn't get scared again. But because he felt like they had ruined everything. Hogwarts doom was really on their hands. But before he could apologize for his stupid behaviour and ignorance of the plan, Dorian heard a loud bang and looked at the door to see....

That the Inferi had come inside!

He didn't care anymore. He let out an eardeafening scream and he had already turned around and ran up the stairways and was halfway when his logical side of his brain told him to stay with the group if he wanted to have a slightly smaller chance of survival.

And so he came back running again.. "WHAT DO I DO?!" he shouted in panic.
