"Merlin," Roger breathed, holding his neck where she had nicked him what had felt like abnormally sharp nails. He stumbled back as Fred grabbed hold of the woman and got enough of his bearings back to point his wand at her. But before he could try to talk her down from the obvious fit she was having, he watched in horror as she literally fell apart.
He wasn't fast enough to stop the giant snake as it attacked Fred, but as it turned away from its attack on Fred to lunge again at him, he shouted, "Depulso!" It sent the snake flying away from him, as he hurried over to where Fred had fallen and went about helping him stand. "Can you get up, mate?" He asked, casting a light spell to give the room more light so he could see the snake coming more clearly the next time she attacked.
Whatever the hell was going on, his priority was to get Fred out of there. The bite on his arm didn't look good at all and who knew what kind of poisons this snake had? Roger ignored the pain in his injured arm, as he used it to drag Fred away from the couch and back toward the way they had come to put some distance between them.
"Are you up for going Side-Along?" He asked, not wanting to risk getting lost in the Floo Network with an injured Fred. The only other choice was dragging him out into the open outdoors. And who knew what was waiting there?
