The shock of having his curse deflected again, and at seeing the ghost suddenly become more solid, made Barty audibly gasp. He fell back a couple of steps, mouth falling open behind the mask as the ghost proceeded to shout at him. Listening to her lambast him for attacking Debi, something deep inside pained him, and he gasped again as he realised his control over himself was being threatened.
"Out of the way!" he shouted, desperate to keep control and to finish what he had come to do. He lifted his wand once again, but his hand was shaking, and his other hand went quickly to his head as the usurping soul tried to assert itself.
"Out of the way," he repeated, staggering forward, but his voice was weaker. Somebody was screaming in his ear - no, in his head!
