But I feel like his love for Bianca should have been the focal point of that scene. Like for example, lets say that Bianca wasn't reborn like Nico said and that part was never mentioned. Maybe Nico wanted the scepter because he thought that it would allow him to find his sister in the Underworld, who had been hiding from him like she had done in the original series. Nico thinks that if he finds her, he can bring her back to life like he did with Hazel. However Bianca herself is content being dead, but Nico loves her so much that he wants to bring her back against her wishes.

Anyway, then when they meet Cupid, he gets Nico to realize that love is putting another's wishes before your own and he gives Nico the scepter now that Nico won't use it to find Bianca. Nico then uses the scepter to talk to Bianca's ghost and the two have a quick talk, which allows Nico to finally put Bianca behind him.
