Natsu's pov
After training with my brother for 3 years I wanted to go back to fairy tale and talk to makarov and tell him about my tranning but I decided to get a cloak and a mask to change my voice cause I knew if the others knew it was me that they would make me stay and never leave again maybe happy missed me all talk to him later

At the guild hall

I walked into a empty room except for makarov Erza gray and happy who looked at him with a death glare I said makarov I need to speak with you in private and the instant I said that I saw a shining object coming towards me I held out my hand and caught it with ease then snapping the blade in half only to get a glare from my attaker Erza scarlet and I said Erza scarlet if you challenged me I will not hesitate on braking bones.makorov motioned me to go to the back room I walked in and sat down and took off the mask and put a silence spell that zeref taught me on the room to minamize risk of being found out and makarov entered and screamed and said where have you been my boy the whole guild thinks you're dead at this point I silenced him by saying I know and when I'm ready I'll reveal that but there's a couple things I'd like to do first promote me to s class and that job list will disappear I can garentee that and tell levy not to worry anymore I know she must be confused why I ran off also keep Erza in the dark she really doesn't need to know that I'm alive and I will tell you about my adventures here and now I started telling him about it

Erzas pov
My blade felt hot after it snapped under  that mans finger tips I was stunned my blades take a lot of fource before breaking the man came out with his hood and mask on and was about to leave when I ran to the door blocking him exit he looked me dead in the eye and said move before I break a rib he had his hand to my chest with his hand right on a rib I said then at least tell me who you are he looked away looked back and said I'm E.N.D and you are going to have to make me bleed to see my face. He then shoved me to the floor with little to no effort and walked out and didn't look back.

Greys pov
After that guy left markov called me into the back room and said natsu is that man and he's been on tenrow island for 3 years traning with his brother and learened how to cast a silence spell apparently also grey before you go screaming the spell is about to go away so be quiet and you can tell everyone except Erza she needs to bee kept in the dark for now I'm astonished master he threatened Erza to keep her in the dark also gray when he tries to leave town don't stop him.
