"Hey there," Derek says gently, stepping up to the carrier as non-threateningly as possible. The baby's eyes blink open and he shifts around until he spots Derek, and he lifts his hand to give the baby a little wave. He's always been a sucker for kids, which seems to surprise some people. He reaches into the carrier and gently touches the tip of his index finger to the baby's chubby little palm, waiting to see if he'll grab on.

"Is it?" Derek asks, looking over at Biffy curiously. "I've got time if you feel like telling it."
