"Like a Kennedy?" Wasn't one of the JFKs called Jack, even though his name was John? He wasn't sure where he plucked that bit of knowledge from. It had to be a movie. He was pretty damn sure he hadn't payed that much attention to history in school.
"Or do you want to name him Jack?" Dean didn't mind either way. He wasn't completely hell bent on naming their son after his Dad. It had just been an idea. Name him after someone... "You know Jack Robert wouldn't be bad." Bobby had sprung to mind. And that did have a nice ring to it. "Jack Robert Winchester..." He said out loud to test it.
