Jackson and Rill have a special relationship. I don't know exactly how mutual it is. He certainly tolerates her. She seems to drive the emotional trajectory, though. She nuzzles him, rubs her head all over his, licks his ears, and likes to sleep curled near his face. Inside, outside, wherever napping is happening she likes to be close. Of course, everyone loves Jackson. But what does he see in her?

Just kidding, Dear Daughter! Rill is demon spawn a perfect angel, as everyone knows. See? True love!
