For a moment, Nico felt like a little kid again. He was tempted to blurt out, That's so cool! Even before he got into Mythomagic, he'd been obsessed with pirates. Probably that was one reason he'd been so smitten with Percy, a son of the sea god.
Nico experienced a rush of nostalgia, momentarily feeling like a child filled with wonder. The excitement he felt was so strong that he had the urge to exclaim his delight. His long-standing fascination with pirates, which predated his interest in Mythomagic, contributed to this feeling.
This passion also played a significant role in his admiration for Percy, the son of the sea god. As Percy epitomized the adventurous spirit of the ocean, Nico’s connection to the sea through Percy intensified his fascination and affection for him.
