Summary
James Daniel Fenton was born a short while before noon, on a sunny September day. He was a premature baby, doctors didn't have much hope for the boy survival.
Daniel James Fenton walked into his parents portal late into the evening of forth July. Fenton parents asked him to look at the wiring, he was always good at finding details easy overlooked by them. Amongst all the fireworks no one heard his scream.
No one noticed the passage of Anti Ecto Acts, not until Harriet Chin started nagging Lois Lane about them.Bookmarked by FrostKitten
