Tom had waited in the snow on the quidditch pitch for half an hour, casting warming charms every few minutes, until eventually he couldn’t take it anymore. He was frozen to the bone without a winter cloak on, and Harry, flying through cold winds wearing indoor robes, must be even colder. Surely, he couldn’t still be flying? But where was he? Tom realized he might have entered the castle from another spot without returning his broom, and called it quits immediately. Harry was likely warming up in the dorms right now.
