"Gray acting like a complete and total dick! Dude, no one gives a hot fuck what you promised your fucking father (whom you barely even know). You don't know anything about E.N.D. or the possible consequences of the actions you are about to do, so don't fucking do them. Patience is a damn virtue, bitch."

Absolutely. With Face gone Gray would have had all the feaking time in the world to sit down and think matters through, but no. Not mister I know everything best.

But even if he's so freaking convinced, why the hell can't he act mature about the matter? Couldn't he just have said "Sorry Natsu, but I promised my father I'd destroy END" right away, instead of going for the "This book here?" practically baiting Natsu to slug him a good one. If he had stated saying "Nanana! You can't haaaave this!" and stuck out his tounge, I wouldn't have been surprised either.
