I already pointed this out to you last time: Natsu DID say more than just "I promised Igneel".

Last time you argued that Gray was under time-pressure due to Face going off any moment now... which didn't even make sense back then since he didn't act, but only taked about acting. But this week Face is already dealt with and there is NOTHING at all preventing Gray from asking Natsu why he doesn't want the book destroyed.

But instead of asking Natsu, Gray chose to taunt him with the book. I wonder what has gone through his mind "Hmm... this book could end up destroying all of us. Should I ask why both my best friend and a 400 year old Dragon want to prevent it's destruction? Nah... I'll just taunt him with it instead. That's so much more fun." maybe?
