Fiat had the childhood from hell. His mom was cruelly abusive verbally and emotionally trying to turn him against everyone only wanting her. His dad sent her away but he treated Fiat horribly and Leo and his family were the ones there for him until Leo's dad was transferred. By the time they came back poor Fiat was doing anything for love. Them coming back really calmed him down.
I just realized that the locket im wearing right now is the same as these two are wearing, just black in color... And from now on this is my fav locket lol
