No, Chris hadn't known his father had been married before his mom. He supposed it made sense, though. Whitelighters lived whole other lives before becoming the guardian angels of the Wiccan world.
How many other kids got to hear their dads talk about the second World War anymore? Not many, and none his age. With a dad that looked pretty young still. He found himself sort of fascinated as he listened to Leo's story. Even if the fact that he'd left his friends to go save strangers didn't sit well with him. That's what his dad did. Helped others, as many as he could. Probably why he'd been chosen to be a whitelighter at all. But it was too similar to the life Chris had lived. Leo always helping others, never being there for his youngest.
Still, he could see the pain on Leo's face and he tried to offer a comforting smile. "Guess that's why you got chosen, then. Helping strangers and all. Mom named me after your dad. What was he like?"
