User blog comment:Maimer1882/Nicos's Importance to Gaea/@comment-4132675-20111108043413/@comment-4473295-20111111205231

I think she means that Gaea can't kill Nico because then Hazel could contact him, torture wouldn't do anything, and Nico almost found the doors and closed them. She needs Nico out of the equasion and kidnapping him is the only way to guarentee it.
