Carl watched as the Dementor glided away. He did it! He had made it go away! And… he had managed to cast a Corporeal Patronus. The St. Bernard ran back to him and he smiled, reaching out to pat it - but it disappeared as soon as it reached him. Oh well. Thanks for the help, little guy!

Some of the warmth, light and optimism returned to him now that the Dementor was gone. He turned to the woman, who still looked frightened. "Yes, it is. You don't have to worry about it anymore, ma'am." He said and walked closer to her, though cautiously, since he did not know who she was or what she was capable of doing.

As he got a closer look at her, Carl noticed that she was shaking heavily. "Oh, um… Caelum Saepio!" He pointed his wand around the area to cast the Insulation Charm. That would keep them warmer for the time being… "Do you think you can stand up? We'd better get out of here, it's not safe in here." He bent down in front of the woman and offered the hand that was not holding the wand.
