It seemed that the others were sure this was blood. Which was gross. Who would have painted something with blood? That made this all the more sinister and Oliver agreed that they should probably definitely get a professor here. He suddenly remembered that he was not just the oldest of the bunch gathered around the bulletin board, but that he was also a prefect. Right.

"Yes, I think it would be best to alert a professor." He kept his voice steady and calm. No need to freak the young ones out more than they already were. His eyes settled on the Slytherin firstie who had offered to go get someone. "Patrick. Can you go get a professor? Preferably the headmistress, Professor Myers, or Professor Hirsch. If anyone else wants to help, split up, that'll be faster." He wanted some of them to stay there, though, in case something changed. He was also afraid of this painting magically disappearing, as things sometimes did at Hogwarts.
