User blog comment:AquaJayFox/Gon's mom?/@comment-48285-20190811051629

A personal favorite theory on this topic that I have is Gon's mother is a rock, a.k.a the pregnancy stone. The pregnancy stone is one of the specified slot cards for Greed Island and ALL of the Greed Island cards work as intended. They had to have been tested for this so Gon was made via the pregnancy stone. It also explains why "NIGG" was in Gon's book, when he wasn't the first person he had met in the game. You might argue that "NIGG" took Gon to Kite, but Ging had Elena change the detination because of Gon's choice in what card he took out of the game.
