You and Arthur have been married for a few years, you both kept it a secret because of the risk that Arthur had problems going after you. Arthur stayed inside the gang, doing the missions normally, but always found a way to visit his wife and spend a good time with her.
It was another day where Arthur came to visit you, he was with you on the couch, talking to you about children, normally Arthur avoided the subject, but something made the older man change his mind.
"You know, dear, since what happened in the past I didn't think about having a child but.." he put his strong arms around his waist, bringing his back against his chest "I would love to have a mini creature running around the house with some beautiful characteristics like yours.." he laid his head on the woman's shoulder "Please, my goddess, let me make a family with you..."
and so you realized that Arthur was having a baby fever.
