Nico referring to his mom as "Mama" implies he most likely at least used to refer to Hades as "Papa" and i 100% headcanon he still does but mostly in the manner of him having the entire Underworld wrapped around his finger for being the baby of the family
Went out to this super cute little festival this town was having! It was a blast! Lots of little vendors and great food! Then we got some ice cream at this old fashion creamery! I got a chocolate/vanilla twist with rainbow sprinkles in a cone! (It’s the only ice cream I’ll eat 😅)
