Dan nodded at Bryn and gave her a thumbs-up. He'd been fine inside a circle for over an hour, he'd be fine inside one for less than a minute. The boiler wasn't going to blow just yet, and the Overlook couldn't get at him since nothing dead could pass over the flames and he was the only person that was still alive in the entire building.
When he saw Bryn hesitate, he made a shooing gesture with one of his hands and gave her a smile. He'd be fine.
