Yes. I did consider it, but felt Nico needed a reminder of "don't distance yourself from people" and went with a yellow songbird that will remind him of boyfriend

(He sure did. But that Cerberus was supposed to be with the "bad guy". I do like the idea that all three heads have their own personality, though.)

I'd say Nico could talk about his world's Persephone, but he doesn't have the greatest memories of her. She is, but much better than her sisters.

I would love if they eventually talk about the bad stuff, something to work towards. :)
