Dog welcomes the petting. Maybe the hellhound's nature just has changed too much; he feels no need to be demonic, the only thing that hasn't changed is his loyalty to his master - but maybe that isn't quite correct, either, as he's allowed himself to question that too. But Adam is a good kid. A good kid who's upset, and tried to do his best to help his best friend. It hurts Dog to see him that way. 

The hellhound turns his head to lick at Anathema's fingers. She's a friend too, she's proven as such. Humans really aren't so bad. 

"Yeah." The boy responds, but there's a furrow to his brow, and he's mostly looking at his hands, now back on the table. "I think so. I dunno." as he works closer to honesty. 

"It's just a lot to think about." He's had far too much to think about since his birthday.
