Nico knew something about ghosts. Letting them get inside your head was dangerous. He wanted to help Reyna, but since his own strategy was to deal with his problems alone, spurning anyone who tried to get close, he couldn't exactly criticize Reyna for doing the same thing.
Nico understood the peril of allowing ghosts to influence one's thoughts and feelings. He recognized the haunted nature of such experiences and wished to assist Reyna, who was grappling with her own struggles. However, his personal approach to confronting his issues involved pushing people away and managing his problems independently.
This realization made it difficult for Nico to judge Reyna for her similar inclination to isolate herself. He acknowledged that despite his desire to help, he, too, was caught in a cycle of solitude, making it hard to reach out and support others. This internal conflict illustrates the complexities of dealing with emotional burdens.
