I think a lot about Nico trying over and over again to summon Bianca or his mother, only to get nothing for months. And the number of failed tries just kept growing, tens, twenties, and suddenly it was hundreds. And just when he had given up hope, Percy Jackson comes along and she appears. And the first thing she said? “Hello Percy” as if Nico wasn’t even there. And then Bianca, the only person he could remember caring about him, tells him she was hoping he would give up. And not even a day passes before he’s by himself again, with Minos filling him with rage. No wonder Nico was willing to trick Percy to get a shot at knowing anything about his mother. She was the only family he had, and he couldn’t even remember her name. But even with all this, he still made Hades promise not to hurt Percy.
