Vexon pov]
I looked over the wall and saw titans ranging from 2 meters to 15 meters.
Vexon: We need to get back to hq to prep, Mikasa take the lead I'll take the back and try to keep titans off us.
Mikasa nods and uses her ODMgear to head back to hq with the other soldiers I take up the rear after dropping down on some titans. I start to catch up as an abnormal almost bites off my foot , Eren looks back to see me narrowly dodge it.
Eren: Vexon you got a little something right behind you.
Vexon: No shit!! Just keep going I'll keep its attention off you guys and meet you back at hq.
Eren nods and keeps going while I turn around nod hook into two buildings behind me and use them as a slingshot. I send myself through the titans neck cutting all the way through it's nape. After I see the titan hit the ground dead I head back to hq.
{time skip to hq with everyone panicking}
I walk over to Eren and the others as Jean runs by and knocks Eren over.
Eren: Hey what the hell!
Jean: Oh shut up Jeager, I was so close to becoming an mp and I don't want to deal with any of your shit today.
Vexon:Jean shut the hell up, we all know the only reason you want in on the mp is cause your afraid of the titans well guess what you're dealing with it and if you even think about chickening out I will feed you to a titan my self.
Jean just looked at me then turned around and walked away muttering something under his breath.
I helped Eren off the ground and walked over to a loose board and pulled it away to reveal a cubby hole filled with all sorts of junk.
Armin: What are you doing?
Vexon: Digging for something I made in case the shiganshia attack ever happened again.
I pull out a metal bar and reseal the cubby hole.
Eren: What's a little piece of metal going to do to a titan?
Vexon: Eren, never underestimate me or anything I make.
I press a button on the side of the bar and it turns into a gauntlet with another blade in its wrist but unlike my metal arm it goes all the way up to my shoulder.
Vexon: Want to ask me that again Eren or did you learn your lesson about jumping to conclusions.
Eren and the others stand there looking at what I made a shocked but impressed especially Mikasa. A soldier walks up to us and tells Mikasa to help him since she's in his squad for the moment.
Mikasa: Vexon, Armin keep Eren safe please.
Armin: I will
Vexon: You have my word.
With that Mikasa walks off with the soldier while me, Eren and Armin head off in another direction to attack the titans head on with a few other soldiers. We all go over to the other side of the wall and I over hear Eren and a guy named Thomas challenge each other to see who can kill more titans. After they finished an abnormal jumps at us and slams face first into a building. Everyone stops on the roof of a building not to far away and stare at it while I count the people in my squad.
Vexon: oh no" I mumble under my breath as I look at the titan while it looks at us with Thomas in its mouth as he tries to tell us to help him. Before anyone could react the titan bites him in half and tosses his top half into its mouth. Everyone but Eren watch the titan walk away in fear.
Eren: You bastard!!! I'll kill you!!!
Vexon: Eren get back here!
I begin to chase Eren as a titan steps in front of me.
Vexon: Stop Eren before he does something stupid I'll hold off the titan.
Everyone replies with the standard Yes sir as they chase after Eren.
Mikasa pov]
My squad was sent to make sure everyone got out of the city safely. I notice that the gate has been blocked by a man with a cart.
Mikasa: Why are you keeping all these people back cause of some stupid goods.
Merchant guy: Tell them to push and I'll get out of there way.
Mikasa: People are dying to save people like you and all you care about is your stupid goods.
Merchant: So there just soldiers who cares if they die there doing there job.
I reach for my sword and the guys body guards get in the way, I knock them out with out trying and toss the merchant off the cart.
Mikasa: To be honest I don't think scum like you should be allowed to live.
Me and some of my team move the cart out of the way and get people through the gate without any more problems.
Armin pov]
I follow Eren as he chases the titan that ate Thomas but then a titan jumps off and bites his leg off and he crashes into a building. As the others catch up to me a titan grabs one and eats him before he can even yell for help. I land next to Eren as another soldier goes to land on the other side of Eren but then gets swatted out of the sky by a titan. I stare at Eren in horror and then notice a titan with a beard lift me up over his mouth. I get dropped and as I'm about to be eaten Eren grabs my hand and throws me on the roof he was on then gets swallowed by the titan as it walks away. Vexon arrives shortly after and Mikasa also shows up a little later.
Vexon: Pov]
I see Armin on his knees with tears forming in his eyes and after what he saw I don't blame him shortly after Mikasa arrived and noticed the look Armin had.
Mikasa: Armin where's Eren.
Armin doesn't answer he just keeps starring at the titan as it walks away.
Vexon: Mikasa he needs some time I'll tell you what happened but you have to promise that after I do you will head straight for the supply building and stay there I'll head after that titan.
Mikasa nods and steps towards me.
Vexon: Mikasa, Erens in that titans stomach by to looks he's lost a hand but he could still be alive.
Mikasa stares into my eyes with tears forming. I give her a hug trying to make a difference in her mood but I know it won't do anything.
Vexon: Remember what I said you and Armin head to the supply building and wait for me to get there I'm going to get Eren.
I turn in the direction of the titan after I watch them head towards the building. Eventually I pass the titan and do what I did before to send me through the titans mouth except this time I keep my blades hidden and go straight into the titans stomach.
Mikasa pov]
I head back to the supply building but I go against Vexon's wishes and kill the occasional titan along the way till I run out of gas and crash into an ally way. I hear Armin stop on a roof across from me just as a titan sees me and heads in my direction then I hear another pair of titan foot steps behind me.
Vexon: Mikasa! Mooovvvee!
I look up at the titan behind me and see Vexon on its shoulder then I see the titan step over me and punch the other in the face.
Vexon pov]
I drop down from the titans shoulder and help Mikasa up as the titan kills the other titan.
Mikasa: How were you not killed by that titan?!
I chuckled a bit.
Vexon: Would you believe me if I said that was someone we know as that titan.
Mikasa gives me a look that says wtf are you talking about. The titan let's off a loud victory roar as Armin lands next to me.
Vexon: that's actually Eren.
Everyone looks up as titan Eren stands in front of us looking out for other titans.
Vexon: Good job Eren follow me and I'll lead you to more titans to kill.
Eren just let's off another yell as I carry Mikasa and Armin follows behind with Eren right on his heels. We pass by some of the other troops who see this and get ready to attack.
Vexon: Don't attack him he only kills titans!
The others just look at each other confused then back at me.
Vexon: Head to the supply building and get inside but leave the titans alone the big guy has them taken care of.
I say this and the others do as I say without a word. Shortly we arrive at the building and I put Mikasa on the roof gently. Once everyone else is up where I am  Eren starts killing titans to he becomes over taken by there superior numbers. I jump down and land on a titans back with both my Blades stuck in its nape I then run over three more titans killing one as I start to kill another. Eventually Eren is able to get back on his feet and kill the other titans with ease. Everyone looks down at Eren as his titan form dies and normal him appears out of his nape.
Vexon: See what I tell you.
I grab Eren and bring him up to the roof and Mikasa checks him for a pulse. When she finally finds one she starts to cry tears of joy and hugs me tightly and keeps thanking me for what I did to save him. I hug back after she loosens her grip cause she was squeezing the air out of me. After we finally stop I look over and see horse head Jean glare at me with fire in his eyes.
Vexon: What's the matter Jean jealous much.
When I say that his face turns bright red and he looks away quickly. I look back at Mikasa as she slaps me across the face.
Mikasa: That was for scaring me.
Vexon: Ok I guess I deserve...
I'm unable to finish due to Mikasa kissing me.
Mikasa: That was for coming back with Eren.
I stand there with a deep shade of red over my face as everyone else especially Jean stare at me with there mouths hung open.
Eren: Looks like someone has a crush.
We both look down at Eren as he says that weakly and winces from the pain.
Vexon and Mikasa: Oh shut up.
We both crouch down and help Eren stand and make sure he doesn't fall off the building. We begin to walk back to the wall as a pain shoots through my left arm which makes me drop to the ground holding my arm. I try to pull off the metal that covers my hand but it doesn't budge. Everyone turns back at me as I fight to get the metal off my arm.
Connie: What's going on?
I flip over my arm and hit the emergency power off button through the metal that concealed it and it shoots off my arm.
Vexon: Fucking hell.
Armin: What happened?! What's wrong with your arm?
I look at it and see a ton of burns and deep cuts going all the way up to my shoulder.
Vexon: It's nothing. The arm just acted up is all.
Mikasa: It doesn't look like nothing.
Krista walks up to me and try's to help me up put refuse.
Vexon: I can do this myself, I don't need any sympathy.
I open the compartment in my right arm and pull out a small med kit and begin cleaning and stitching up my wounds.
Sasha: What caused all that.
Vexon: That arm was a prototype I've been working on I knew I couldn't take on as many titans as I did with out it. I knew it would do that but I took the risk anyway.
Krista: Well next time don't do stuff like that. You had us scared for a minute there.
I finish stitching my wound and as I put away the med kit the picture of me and my sister falls out and lands next to Krista.
Krista: What's this?
She picks it up and looks at it then flips it over and finds the note on the back and begins to read it out loud.
Krista: Dear big brother. I'll never forget what you sacrificed for me and I wanted to...
I put my hand over Krista's mouth that keep her from finishing. But Sasha grabs it before I could take it from Krista and reads the rest out loud.
Sasha: I wanted to repay you so I got us both some necklaces that go together and I also got you this picture of me when I was 3 and you when you were 7. Love you Vexon sincerely your lil sister Emily.
I look down at the ground defeated tears forming in my eyes. I get up and take the picture from Sasha and put it back in the compartment in my arm and seal it shut.
Vexon: Good job now I'm in a bad mood so what ever your mission was right there, congrats you did it.
I walk over to the wall and sit down with my head in my hands as everyone stares at me. Krista walks over to me and sits a few feet away from me then scoots a little closer.
Vexon: What do you want?
Krista: I want to know what happened.
Vexon: Well you're going to have to wait a long time to get that info out of me.
Mikasa: Is there a quicker way to get you to tell us.
Vexon: The only other way your going to get that info out of me is to get me drunk.
Connie: Then that should be easy.
Vexon: Wrong... After seeing what I witnessed I ran for three days straight without stopping till I managed to get to shiganshia immediately upon entering I got as much beer as I could and chugged it down to the point where my alcohol tolerance is off the charts. Then the day before the attack while I had what was probably the worst hangover in history I made the prototype for my right which Eren and Mikasa know what it looked like.
Eren: Damn.
I stood up and faced my team then walked backwards to the edge of the wall.
Armin: Vexon what are you doing!
Vexon: I'm taking a break from reality I'll see you in a bit.
With that I jumped off the wall and turned around and used my gear to send me to the forest just outside of the training camp.

A/n--- Taaadaaa that's one girl. * gets slapped by Mikasa again* hey stop that!. Anyway the team just dug a bit deeper into Vexon's past but Vexon won't talk about it and some people such as Armin are still wondering how he knew that Eren was the titan.
Armin: hey can't you just tell me how he knew that titan was Eren.
Me: Nope sorry you'll have to wait till next chapter.
Armin: Damn you.
