The Frio brothers may have a nice house, but they have personality issues which make them less than ideal as boyfriend material. If you look in Claire Ursine's family tree, her baby's father is Jared Frio. The Frio Family consists of two young adult brothers, Connor and Jared, who are completely different from each other. Connor is lonely and quiet, while Jared is outgoing yet mean to his friends. Jared's ex-girlfriend is his neighbour Claire Ursine, who is pregnant with his child.
In their description it says that both of them are cool, in different ways, and "Frio" in Spanish and Portuguese literally translates into "cold".

There is a Sim in Lunar Lakes named Paulo Frio, and his relation to the family is unknown.
