"Morning, Dad," Dan replied, just as quiet and not looking up from his book. "I got you coffee and breakfast," he added after a minute or so, still caught up in the story, and gestured vaguely towards the stuff on the table, before glancing at his hand. He'd taken to checking that he hadn't accidentally died without noticing it every so often, and yeah, he was still alive.
Then he actually looked up at Jack and smiled. "Sorry, I was reading," he explained, somewhat pointlessly, and held the book up as extra proof before putting a marker in it and setting it to the side. "How're you? Sleep okay?"
