~A few seconds before Eren realized Harry was there~

Adjusting his stance he looks around, only to stop and stare.

His eyes can't help, but stay stuck towards the beautiful sight above him, the Aurora borealis-like spectacle entrapping the newly ascended deity.

Harry can see everything inside the…'strings? No branches reaching out like?'

'Like paths!'

'This must be the tree of life' he muses.

"Yeah. I saw it four years ago: I saw my own future through Dad's memories." The older voice of Eren makes him jolt as he spins to see him talking to a blonde man.

'What's going on?' He's dealt with enough time travel to know he's not in the present.

Honestly, the amount of times using the time turner to stop a criminal's action felt pretty cheating like, and he wondered why the aurors never used the method before Hermione suggested it.

"What a sight it was." Eren's voice brings him back from his thoughts, he needs to stop drifting.

He starts towards them just as the Blonde stands next to..!

'Is that a chained Eren!' He hasn't fully registered what he was seeing until now.

His steps increase as a rage enters him, never seeing the sand under his feet flick and twirl as his magic responds with little effort, the hold death had on his emotions are gone.

"Founder Ymir!" The blonde yells over Erens shoulder as the boy starts to frantically pull at his wrists.

Harry's mind almost goes blank when he sees the blood starting to drip from cuffs.

"Make Eldians unable to reproduce anymore!" The blonde screams annoying Harry.

"What the hell is going on!" He tries to ask.

"No! Ymir stop!" The desperate yell of Eren drowns out his growled question as he nears.

He almost feels insulted that Eren hasn't noticed him.

"Eren, Our father…He regretted listening to you." The man says as Eren starts to pull his hands out regardless of his health.

"I don't know what sort of future you saw through Father's memories, but you didn't see everything, right?" The smug tilt to the man's face makes Harry twitch with agitation, the fact that they're ignoring him only makes it worse.

"For example, you didn't know you couldn't use the Founder's power here."

'Oh so this is about power' his mind purrs the anger fueling a vindictive side, he doesn't see a figure materialize behind him.

"You're as powerless as ever." That makes Harry snap.

"Eren what the fuck is going on here?" He growls out.

The comedic effect of them whipping their heads around in shock is lost with the blood dripping off erens fingers.

"Harry!" The dubious shouts make his lip twitch despite the situation, he clearly has a relationship with both of them.

"You do" the voice behind him makes him start, spinning around he can't help but groan.

"Oh, come on" he is staring at himself, who looks older though that's not saying much.

Turning his gaze around he curls a brow at the fact that the two in front of him are moving at an impossibly slow speed.

"New ability?" He can't help but ask.

"Ah yeah, we have a shit ton of cool shit we can do now, but look you need to go back and deal with the shit that's happening in the past, make sure to give a certain shorty a good healthy fear of god, trust me he deserves it" Harry stares as he watches himself lecture…himself?

"Ah okay?" He questioned.

"Can you explain what the hell is happening?" He wonders if he'll be a dick to himself?

"You aren't in the right mindset to deal with this"

'I'll take that as a yes'

"I got this part, you just make sure our people stay alive, and don't beat yourself up about some of the things that will happen." His future self really thinks so little of him.

"We got a plan."

"Now go" Harry feels his future self shove him, as he starts to disappear from he hears one last bit of advice.

"And give those uprights hell!"

'Fucker' he thinks about himself.

-———-

'Ouch, why'd he-I have to be so violent with the shove,' Harry thinks as he lays there on the ground.

Being shoved into your physical body is not something Harry would recommend. Wincing he sits up and finds that he had been thrown off the wall, luckily his body isn't injured, though he can feel the phantom pains in the back of his mind.

The sudden sounds of footfalls makes him throw his hand out instinctively as the presence of a Titan nears, watching in mild fascination as the being dissolves into nothing, by a flick of the wrist.

He stares at the particles drifting onto the ground, while marveling how easy his magic responds to him.

He doesn't have time to reflect on his new condition, the pulsing of the monitoring charms reminds him of that. Standing up he wobbles and uses a tree he's by waiting until he gains his equilibrium.

Using his mind's eye he tracks down all the monitoring charms he has placed on those he cares for, he heart skips as Thomas, Mina, and Marco's register them being gone.

'No' if only he didn't let Bertolt's revelation catch him off guard.

If he thinks back to it, the signs were there, Bertold would feel anxious at every occurence of the colossal, he seemed to be hesitant on making connections as well.

the fact that they were outside the walls, should have been a blanant sign.

Never let it be said Harry isn't oblivious to the most obvious sometimes.

Staring at the massive boulder plugging the hole, that used to be, in confusion.

He knows these people don't have the technology to do this, and he certainly didn't do anything?

'Is there someone with a shifting ability here?' He knows the founder is one of the titans that are in the walls though he hasn't seen anyone with the-

How stupid can he get, the feeling he felt from Eren is the same he felt from Bertolt and the two blonde's.

"I'm glad Hermione isn't here" he can't help but mutter.

Apparating onto the top of the wall he feels déjà vu as he gazes at the distraction that has unfolded while he was out.

'I have to talk to those kids' thinking of the three Titan shifters, though he doesn't know what, or which one the girl is.

He ignores the flickering in his mind that shows him where the bodies of the three innocents are. He definitely ignores the fact that he can feel their phantom deaths as he gazes over the desolate town that had been so lively only…hours ago?

He doesn't know how much time has past but, with the nervous and scared feeling's eluding from his charges he reaches for their essence and apparates towards them, the destruction fading behind him as he instantaneously travels to the roof to the courthouse, his foresight to learn the layout of every major place was a good one in his opinion.

He gazes around looking for the particular MP that knows him, through the king, spotting the undercover spy he apparates silently behind the man, his body hidden from the shadows.

"Hullo, king's mutt. Or Kenny's bitch whichever" he pauses delighted in his jolt.

The man turns to him, his eyes widening as he sputters, "But the boy said you died!?"

Harry is lucky he set a privacy ward.

"Well, let's just say I am extremely hard to kill" he stares before growing serious as his three charge's emotions start to climb.

As much as he wants to get in guns, or wand's blazing, he's learned that the more information he has before acting the better.

"Now tell me what the hell is going on?" He knows they're aren't his, but dammit if he doesn't consider them his.

"T-they are currently prosecuted for their threat to humanity" the man stutters out, knowing and having been told to treat the man with care until the king is ready for whatever he has planned.

"What do you mean? You know never mind I don't have the pa-" everyone in the vicinity of the courtyard suddenly froze, when the most terrifying sensation crawls over them, most look frantically assuming a Titan is near, some of more resilient soldiers stand in a defense for an enemy they can't see.

Bertolt gives both Annie and Reiner a startled glance as they feel the sensation ticking their spines they physically have to stop themselves from shifting in pure defensive instincts.

"You alright" they hear Connie ask, verily hastily tries to distract them, never seeing the intense eyes of Ymir who watches them tense as she had.

Harry felt the determination and then sudden flashes of pain and fear in his favorite maniac, and he hasn't had full control over himself in five years he wants to let loose, something in his mind purrs at the thought of releasing his pent up emotions.

Stalking away from the No named spy he absently obliviates the man, not feeling like dealing with their shit.

Stalking past the guards he ignores their attempts to stop him, while he prowls towards the double doors he can hear the sounds of flesh being hit, along with the pained noises of his brother. Dogging the hands of those trying to stop him he simply glares at them, watching with satisfaction as they wilt and fumble under his gaze.

"You can't go in there, it's a private trial!" One of the braver guards try to stop him as he nears the door.

"I don't give a fuck, now get the hell out of my way!" With that he uses his magic to shove them off slightly,

Focusing on the door it flings open, revealing the sight of Levi standing over Eren who is.

'Chained!' His mind growls, seriously tired of seeing his brother in chains right now.

The fact that the man he respected is standing over his brother berating him up while in chains!

"Harry!?" The voices of Mikasa, and Armin make him turn to their relieved gazes, he can see the same murder in Mikasa's eyes at Erens treatment.

"Har'hi" Eren's muffled voice makes him quip his head toward the boy, he doesn't realize the last restraint on his magic broke at the sight. Stalking over to his ward he stares Levi in the eyes as he backs away.

"H-hey what are you doing this is a priva-" the pompous ass that was speaking is silenced.

"Enough! I don't care what is going on, what gives you the right to treat a child like this?" He snarls as he side steps Levi, ignoring the man, he doesn't know why Levi has done this and doesn't care, if he's honest.

"Zackary I thought better of you, Shadis has always spoken highly of you, but to see that you'd condone a child to be tortured…I'm not so sure" he speaks the the white haired man. His aura leaking barely concealed rage.

Gently cradling Eren's face he sighs as he can see the healing already working.

"Hey, I'm sorry for the scare" he murmurs, pulling the distraught boy into his lab, the chain's dissipating with a thought. He gently cascades his hands through the boy as he feels tears leak onto his shoulder.

"T-the boy's free what if he kills us" the frantic voice of a scared lord speaks, ensuing chaos.

Harry stands up as everyone starts shouting, he positions himself over Eren his magic pulling as he starts to apparate to his other wards, he ignores how Levi shifts protectively in front of them.

"Supreme Commander! I have a proposition!" A shout over rides everyone making them freeze all turn to see Erwin raising his hand to address the man.

"What is it?" The aged man asked never taking his eyes of the biggest threat, and it's not the boy.

"Eren's Titan power has a multitude of uncertainties and unknown elements." The man starts

"It is exceedingly dangerous." Zachary allows, his gaze still trapped by the man before him.

"why don't we put Eren under Captain Levi's command and send them on a mission outside the Walls?" This makes him look away, though it's only cause the other broke his gaze to look at Erwin too.

"Eren as well?" He states rather than asks.

"Yes…"

" Whether Eren can control his Titan power, and whether he may be of benefit to mankind, should be decided based on the results of that mission. "

"Watch over Eren Jaeger... Can you do that, Levi?" Zackary asks.

"I can definitely k*ll him." Zachary winces at the fierce scowl being aimed at their strongest.

"You'll what" Harry hisses out, his anger making hos parseltongue more prominent, though his animagus doesn't help either.

"Alright, but first we need to find out who this is? …Mr.?" Zachary states, feeling slight amusement as the man suddenly becomes sheepish now that his brother isn't in immediate danger.

A/n;

How does Erwin react to the strange being that is Harry? Him and hange are cunning enough to have seen the doors opening by themselves.

Has Levi set back Harry and his relationship?

Will Harry be analytical like Armin after finding out the reason or hold a grudge like Mikasa's? Both?

Sorry if this isn't the best. I had major writer's block for this particular chapter.
