Returning his attention to Emma, Skater adjusted the spare shirt he left with her when she was sleeping by herself. The bit about the shirt had been a tip from Elvis. Usually it was a fairly clean shirt he’d worn the day before, one that still carried the smell of him on it. The troll had explained that young children relied more on a sense of smell to identify their parents than sight or hearing. Those senses developed later. The shirt comforted Emma while she slept, giving her the illusion that Skater was with her.
