You had convinced Nico to teach you how to play the card game he loved as a kid… Mythomagic. You were sitting on the floor of his cabin (cabin 13, hades) and he was showing you his cards and teaching you what does what… he got really excited when he saw you were actually paying attention to him.. it was sweet, he was usually so dark and brooding.

“Nah you need a hydra card to beat this one"
