Jack Darby grew up knowing that his dad had left him and his mom when he was young. When Jack, along with Miko and Raf, met the Autobots, he never thought he would discover who his father was and what he was, along with their newly discovered older siblings. This changes everything about how the entire team views both Cybertron and Earth.
This is inspired by The Son of Primus, written by owen2su, because there aren't any stories based on this concept.
