Natsu sat guard over Lucy's unconscious body that lied on the ground. The book wouldn't allow him to touch it this time, and Lucy was too fragile to pick up and move on this stae, so Natsu just left her there as he kept all of his senses alert.

Has she been corrupted? Because she would never kill her friends. Even if they betrayed her. Is she really falling to evil because of me? Or was this of her own free will? He thought as he stared at the sky. 

A few hours later, Lucy began to wake up.

 "How long have I been out?" She asked as she rubbed her head.

 "A few good hours. Do you remember what happened before you passed out?" He asked, looking over at her.

 "Yep. I made you kill Levy and Juvia and choke hold Erza, then you wrote one the ground, telling them to leave before I lost my sanity, or humanity. One of those." She said.

 "Do... Do you regret doing any of that?" Natsu stuttered, not sure how she was going to answer.

 "Honestly, no. No I don't. I mean, they're not the first people I've made you kill, and even so, I think they deserved a little wake up call to my abilities now." She said with a dead face, stadium up and picking up the open book.

 "Those are my abilities thank you very much. You just use me to your advantage." Natsu corrected as he too got up.

 "Fine. Your abilities. Now, you wanted to see King Zeref and Queen Mavis, right? I'll take you then."

 She placed the book in her bag, keeping it open mind you, and began walking. Natsu walked next to her as he thought about what was going to happen.

 I'm coming for you Zeref. You'll pay for what you did to me.
