His father-- Gregory never really got to know his father, but even at this age knew he was a scientist of some kind. Gregory was so excited to follow in the steps of his father and continue his legacy, listening to stories about him with a ravenous interest.

His mother-- He remembers her more than his father. Some days he seems like he's processing things well, but when something reminds him of her, he starts crying all over again.

Gregory's friend-- A kid Gregory plays with, the pair are mostly just friends because Eymo is friends with them. They're both very quiet, so they tend to mostly just engage in parallel play when it's just the two of them. Don't take your eye off them, though-- they tend to get into mischief when left alone.

Gregory's best friend-- Eymo is a super open and artistic kid who tends to just adopt the nearest introvert every time he gets the chance. He's the glue holding Gregory together while going through the loss of his parents. Gregory is surprised that Eymo is still here, thinking he'd be any adopting parent's dream child.

Eymo's friend-- Unlike Recrium, Gregory was never able to really connect with Juibi, which is weird for him since Juibi seems a lot less friendly when it's just the two of them. It's really confusing for the poor kid, and he just keeps it all to himself, not wanting to be outside of the loop.

Gregory's Familiar-- Domino helps Gregory with his physical therapy (for his legs) and tells him stories about his family. Gregory considers the cat to be the closest thing he has to family left... he doesn't count his extended family.

An Orphanage Volunteer-- Gregory feels safer with Ruby that he does any remaining family he has left. Being another necromancer, she tried her best to help him learn to move through the air on top of tutoring him in reading. (Greg is dyslexic) If it was up to him, he'd go home with her, not his jailed uncles.
