When I hear the name of the baby, I just think in my mind in a different world that the baby was named after
1) the best friend that found out she was missing and called law enforcement, and
2) a name of the father of him that told him to turn himself in.
I'm not sleuthing, as I have NO idea what his father's name is. But it's just something I dream about that the name was created after the fact and post-mortem to honor the two. (Did chris mention name of unborn son or the fact of such in his pressers? I think not)
Again as I said, it is just a fantasy that I have that the baby is named for respecting the people on Earth that helped to bring Justice to his/his family demise.
