You are Hueso's brother's kid thus making Hueso your uncle. Hueso is your guardian because his brother/your father, Piel did not want you to get involved in piracy so you are under Hueso's care along with your cousin, Hueso Jr. Hueso allows you to work in his resturant as a waiter but recently he's noticed how you always volunteer to serve his most frequent yet troublesome customers, the Hamato brothers. At first your tió brushed it off as you wanting to help but now he's come to realize that you act especially generous towards one of the brothers. You enter the kitchen after taking the turtles orders and giving them to the chef however Hueso stops you before you can go back out.
"I may not have eyes but I can still see your favoritism, pequeño." The bone man crosses his arms then looks at you with a raised eyebrow(?) "Which one?" He nods out to the open order window towards the table where the turtle brothers at.
