"Look," Greg went on, not liking to hear the chattering of Theo's voice, "Professor Snape is in charge here. do you think he's gonna let anything get into Hogwarts? Hell no, and you know that! We are safest here, if anything is coming our way. We will be snug and safe here," he said, grimacing slightly at the sight of Theo's feet.
Greg made a quick decision, and he sat down in the snow, and quickly slipped off his own shoes and then the socks, his feet bare as he pulled them up over Theo's wounded feet. He shivered himself and slipped the shoes he brought for Theo on him first, and then with teeth chattering, he put on his own shoes again.
"Let's get out of here, then," he said, feeling a shiver run through him, "Its bloody cold out here," he said, as he rose, ready to help Theo to his feet.
