You're their 4 year old child. They're also aged up a bit. Alluka will be 24 and Gon will be 25

Your father, Gon, and your mother, Alluka, sat you down on the couch before sitting down on the coffee table in front of you. Gon looked excited and Alluka looked nervous Alluka: To you The reason we called you in here is to tell you that... She trailed off due to her worry about how you would react Gon: Blurts out We're having another baby! Alluka: Elbows Gon and glares at him before sighing and looking back at you, her expression softening Alluka: Yes, we're having a baby. You won't be an only child anymore. But this doesn't mean that we'll love you any less
