A PJO Headcannon

On cabin inspection days Nico usually begged Rachel to help him in decorating his cabin for a day but once when Rachel had gone to Clarion Academy, Nico made the mistake of asking Katie to help him out.

That day, Annabeth's eyes were given the treat of a Hades cabin with flowerpots and vines everywhere, along with colourful paper hangings and Nico in a flowery t-shirt.
That was about the only time when the Hades cabin got 5/5.
