A/N : So sorry guys to make you wait this long, it's just that the day I uploaded the first chapter, I was going to make and upload this a week later, but the next day, I caught the damn virus, and later on the Manga Finale dropped, after which many others things happened which I won't uninterest y'all with. I felt like I owed you all to finish this story I started, so here is the 2nd chapter, which I hope you'll like, also I made an Iron Man reference from the first AVENGERS movie, you'll know it when you have read it hopefully, Please, R and R.

The Plan

Ymir : As you know, the Attack Titan can foresee the future by allowing the holder to experience the memories of not only the previous, but also the future holders. This, in the future holders' point of view, can be considered as sending their memories back to the past, as the future holders have the liberty of deciding what memories are to be sent back.

Eren upon hearing this, was in agreement as he himself had done exactly that when he had manipulated Grisha in stealing the power of the Founding Titan from the royal family. Ymir continued.

Ymir: As you can see the Founding Titan possesses immense power, and can control Pure Titans and is even able to take away, a Titan Shifter's power. It however can also amplify the power of other Shifters, not only boosting the power of their abilities, but unlocking other, more advanced abilities related to their current ones as well.

Eren, was intrigued, but not surprised, as the 145th king had used this power in order to make the colossals harden in place. However Ymir's next words did make his jaw drop.

Ymir : In your case, as we know the Attack Titan can send back memories of the future holders to the holders of the past along with the vice-versa. With the power amplifying boost of the Founding Titan, you can send back not only memories, but your whole conscience, your own mind, back to the past. Although the reach of this power is still, only to the past Attack Titan holders.

Eren : Whoa, so you mean I can send my own consciousness to the past.

Ymir nodded in affirmative but then Eren's expression darkened.

Eren : No, all my talk of Freedom was never false. I can never usurp the body of another person and thus, take his freedom.

Ymir : I understand how you're feeling Eren, but no, that's not necessary, although memories of past can be received by the current holder, in your case this list also includes the future holders and the memories deemed by them to be suitable for being sent back. Howsoever the amplifying power of the Founder, you can not only choose the holder on the recipient end, but also choose the time when he or she receives it, with pinpoint precision. Also, this means that even you can be on the recipient end yourself. I mean to say, you can send back the knowledge you have gained, or even your own conscience, back to your past self, or it's body, depending upon what you choose to do.

Eren : Even if I would be able do that, I can not send my memories back to the past as my past self would never believe the steps I have had taken to get, to be truly taken by me, or should I say us. It could also be that, my past self may truly believe what I have done until now, and end up being plagued by it and the suicidal depression & self destruction associated with it. I doubt he could even carry it out, if he saw the way I had treated Mikasa and Armin. Also, regarding the transferring of my conscience to the body of my past self, it would be really hard for me to adjust, to see Commander Erwin, Section-commander Hanji, Sasha, and the faces of all those comrades of the Survey Corps as well as Commander Pixis, and other members of the Garrison regiment, who have perished till now.

Eren, was deep in thought about what to do, with Ymir watching him. Suddenly a light bulb went off in his head.

Eren : Ymir, you, when you were alive, you possessed all nine Titan powers, right?

Ymir : Yes, yes I was, Although now I am just the Founder.

Eren : then that would make you the first Attack Titan as well, right?

It was now Ymir's turn to be surprised as she grasped onto what Eren had planned. Eren continued explaining his plan.

Eren : When I first saw you, Zeke told me that you made half of his body and every Titan in existence from the soil of the Paths. So, just as you said, then can you send back your own memories, to your past self, thus briefing her about everything that we have discussed, and telling her to make me a human body?

Ymir : Yes... That may be possible.

Eren was in thought about the next step, as Ymir asked him the question he still hadn't answered.

Ymir: All this is correct, but then, you still have not answered. If given the choice to go back, at which point of time, will you go back to?

Eren : I think...

(A sadistic look briefly appears on his face)

Eren : I would prefer to go back to when Rod Reiss tried to manipulate Historia and kill me to take back the Founding Titan stolen by my father.

Ymir : Who is this, you speak of?

Eren : You know, the true ruler of the Walls, before Historia, the one whose Titan form was twice the size of colossals?

Ymir : Although, that narrows the list down, I am still unable to recall which one was him, as I have been here for 2000 years, making Titans of all shapes and sizes, you know?

Eren : but still, he was like mountain, a steam-spewing, flaming-hot mountain, you must have spent weeks, if not months,making that.

Ymir : As Zeke told you, whatever happens here, happens in the blink of an eye. The time I spent making your Founding Titan body would be around 400 days in your world, however, when you convinced me to realise my own freedom and help your cause, did it not instantaneously appear from where your decapitated head and body laid?

Eren : Yeah, now I get it. Here take my hand.

Ymir, knowing what he said, took it and went into his memories.

She saw all the events that transpired during the Royal government arc

Historia revealing her past... Eren viewing Frieda and her memories... the fake kidnapping of Eren and Historia... the talk between Eren and Historia about Frieda... Nifa's revelation about Historia's true lineage and the ensuing tumble caused by Levi... the entry of Captain Kenny Ackerman in the picture... The first confrontation with Rod Reiss... Rod and Historia talking while Eren being held up in chains... Eren re-experiencing his father slaughtering the Reiss family for the first time and his death at Eren's hands as a Pure Titan... Rod telling Eren and Historia about the role of the Founding Titan in the creation of the 3 Walls and the ritual of the transfer of power in the Reiss family for the past century, and Kenny's betrayal... Kenny recalling his past and the story told by his grandfather on his deathbed, about the minority Asian and Ackerman clans... the tussle between Rod and Kenny and Kenny revealing the true motive and nature of Rod and what he did to her mother... Historia being conflicted with her choice-to-be-made... Eren asking her to become a Titan and eat him, in order to save humanity... Rod revealing the knowledge about the restraints on the Founding Titan's power imposed due to the 145th King Karl Fritz's ideology... Historia breaking the syringe and tackling Rod to the ground, and starting to unlock Eren's shackles... Rod licking the serum splashed on the ground and transforming... the arrival of the Survey Corps on the scene... Eren ingesting the contents of the Armor bottle, his subsequent transformation and the first ever use of his hardening ability, to save his friends from the collapsing crystalline cavern... Rod's Titan emerging from under the chapel, and its march towards the Orvud district, ignoring the Survey Corps due to being attracted by the large concentration of human population, clearly showing it's trait as an Abnormal, along with the burning cracks throughout it's body, and leaving a burning trail behind... Eren and the Corps escaping the cavern, and moving towards Orvud on horseback, overtaking the Titan and meeting up with the Garrison district commander there... the evacuation of the district and the planning by Erwin and the others... Rod's arrival and the Scouts' counter... those three kids seeing the Abnormal, and fleeing, but stopping upon Eren's transformation, being filled with hope... Eren flinging the net containing dozens of barrels of gunpowder down the Titan's throat and the ensuring explosion and finally Squad Levi and Historia finishing off the Vitals.

Ymir exclaimed : Okay, so that's the time you wish to go back to, then?

Eren : Yes, Rod was a behemoth, I could have maybe controlled him with the partial power of the Founding Titan, if I had known back then that the Smiling Titan was also of Royal blood, but there were a lot of unknowns back then as even after touching it I had not tried to control it, ordering other pure Titans to finish it off instead, therefore I couldn't know if I could control a Royal blooded pure Titan or not, also whether physical contact through the Titan body would be enough or not, as if I were to approach it in human form then the heat and steam being emitted would have burned me to a crisp. Rod was an imminent danger , A Titan so big that it was not possible to contain him within the walls.

Ymir : What do you plan to do once you go back there.

The Sadistic look again briefly crosses Eren's face.

Eren : as I said, it was too big and a fire hazard aswell, blowing up anything it came near to... ( a look of steel comes on his face, with a fire in his eyes ) and I know just where to put it.

With that being said Eren took Ymir's blessing and she pressed a hand on the coordinate, which glowed briefly but brightly, and although the light was still shining as always, a opening had opened at the base of it, in which, Eren walked into...
