But I just imagine that when Nico, Percy, and Thalia go on quests together, Nico and Thalia are really good at blending in and hiding.
And then, we have Percy.

Like, Thalia would act natural or climb a tree or something.

Nico would fade into the shadows.

And then, Percy would do something Percyish like pretend to be a tree or fall over and try to be a carpet.
