You were walking along the trail in Camp Half Blood when Will Solace, Nico's boyfriend, ran up to you. "I need your help! Nico's singing a song and it's a sad song and I don't know! I can't snap him out of the trance-thing!"
"I'll see if I can help" you reply to Will. You're Nico's half sibling after all. You're both children of Hades. As you approach the Hades cabin you can hear Nico singing a song (the song is called; Overwhelmed remixed by Ryan Mack) as you get closer to the cabin and you hear Nico singing the song. You feel sad because the song reminds you of your worst memories, just like it does to Nico. You remember when you accidentally allowed your shadows to kill your sister... That day the shadows took control... You have tears in your eyes just thinking about it. You decide to open the door and you can see Nico singing the song in the middle of the room. The heartbreak of the song puts tears in your eyes...
