Nico downloads the popular Pokemon Go! app (I am full aware that electronics aren't allowed at Camp Half-Blood, but bear with me) and has to pick his starter Pokemon. Percy happens to walk behind Nico as he murmurs,
"Oh, I dunno. I guess I'll pick Squirtle." Percy snickers, causing Nico to whirl around. Percy replies,
"But why a water type? Last time I checked, I was all about water, and I'm not...."
"Don't you dare, Percy."
"...your type."
