This takes place right at the end of Brotherhood after Father is defeated.
.
Edward Elric once again found himself standing in the empty white void. In front of his portal sat Truth, who was looking very amused.
"I take it you're here to retrieve your brother?" Truth asked. "Just how do you plan on pulling an entire human out of here? What's your payment? Do you attend to offer your own body?" It was quite for a few seconds then Ed gave a small snort, his mouth curling up into a smile.
"Yeah I got your payment right here!" Ed exclaimed pointing back at his gate. "This thing is my portal of truth. So I get to make the decision on how it's used. Is that right?" His smiled turned into a full-fledged grin. Truth watched him in shock for a few seconds before laughing.
"It's come to that!" Truth laughed, putting his hand on his forehead. Ed frowned as Truth continued his fit of laugher. Finally Truth stopped laughing and put his hand down again facing Ed.
"And you're sure about this?" He questioned "You do realize you'll never be able to perform alchemy again without your portal." Ed turned his head and looked at his portal.
"I'm aware of that." He said, "This portal, I know it contains ever secret that alchemy has to offer. However it also lead me astray. I became convinced that I could solve all my problems with alchemy. I couldn't possibly be more wrong. That was just arrogates."
"You're willing to cast it aside?" Truth asked smirking. "To lower yourself to a simple human?"
"What do you mean lower myself?" Ed asked snorting, "That's what I've always been. Just a simple human who couldn't even save a girl with alchemy." Truth started laughing and opened his mouth to admit defeat when suddenly the void started to turn black.
"What's going on?" Ed asked looking around. Black ribbons slowly winded its way toward them, curling around his portal.
"Well this is interesting," Truth said his smile gone, "It seems like Father is still around."
"What? Ed asked, "What do you mean. What's going on?" The blackness continued to spread, and they could hear sinister laugher in the blackness.
"It seems like Father still had some power left." Truth said. "He's using that power to corrupt the portals."
"What's going to happen?!" Ed demanded.
"All dimensions will start collapsing." Truth said, "Usually I start looking for a worthy individual to undo this problem but lucky for me I don't have to look this time. You have proven yourself worthy to handle the responsibility."
"Wait!" Ed exclaimed, "What do you expect me to do? You're not explaining anything!"
"I will send you to the past. You must stop father from making a stone on the promise day. In exchange, I will let your brothers body return to his soul on Earth." Truth said.
"If I go back in time, what's going to happen to everyone on this timeline?" Ed asked.
"This timeline has already ended." Truth said, "You must go to the other timeline now, however that also means whoever is dead is not dead yet. Perhaps you can now save that "little girl" with your alchemy." Ed's eyes widened. "So, what do you say Edward Elric?"
"Fine" Edward said, eyes burning with new determination. Under him an eye appeared and black hands shot out and grabbed him. Ed felt himself being pulling into nothingness.
….
"So it's not you?" A voice was saying to someone. Edward groaned as the darkness swarmed before his eyes.
"Um, no I'm his younger brother." Another voice said. It took Ed a few seconds to realize that it was Al's voice. Ed tried to open his eyes but found it to be too much of an effort.
"But he's tiny!" the first voice said. Edward's eyes shot opened as he sat up, glaring around trying to find the culprit. From around the corner he heard another voice yell.
"OH YEAH CAN A RUNT DO THIS?!" There was a flash of light and the first voice spoke again though his voice was muffled.
"I heard the stories but I never thought they were true. The Fullmetal alchemist is just a little kid?"
"What's going on?" Ed wondered as the commotion continued. "This seems very familiar. Am I really back in time?"
"Well this is a shock." Another voice said in Ed's head. "There shouldn't be two Edward Elrics, unless you're a time traveler…"
"Who's there?" Ed whispered, not wanting to get the attention of the people who were fighting.
"We've met before Edward. I'm Truth." The voice laughed, "There must be quite a big problem in the future for you to be sent here."
"So I'm really in the past?" Ed asked frowning.
"Yes, and you and your brother just took out the Freezing Alchemist." Truth said, "He's just about to escape you guys." Ed heard more yelling and footsteps. As he listened, the footsteps got louder.
"Ha, those fools!" A voice said, "They really thought they could catch me." The Freezing alchemist turned the corner and came face to face with Edward.
"Well you're someone I haven't seen for a while." Ed said amused. The Freezing alchemist froze and stared in utters shock.
"How did you?" He stuttered, looking back over his shoulder.
"So remind me," Ed said smirking, "why are you rampaging the city?" The Freezing alchemist turned back to him.
"I'm doing what must be done!" He exclaimed, his face hardening, "Do you know who you serve and what their plans are?"
"To turn this whole country into a phosphor stone?" Ed asked innocently. The Freezing alchemist gaped at him shocked.
"Y-y-you know already?" he stammered, then his face hardened again. "So you know, and you still are working for him?"
"Nope," Ed said, "I'm trying to stop them."
"But back ther-" he started to say before Ed interrupted him.
"Back there was a different Edward." Ed said. "I'm from the future."
"Do you actually think I'm going to believe that?" he demanded. Edward smirked and beckoned the Freezing alchemist to follow him. The Freezing alchemist looked at Edward suspiciously, then came forward. They went to the end of the ally where they saw Ed and Al walking with the other soldier to report their lost.
"I don't believe it." He muttered. Ed eyed him and suddenly launched forward.
"Ah ha!" he exclaimed. "I knew you had a stone!" Ed held up the philosopher stone in triumph.
"Give that back!" The Freezing Alchemist yelled launching at Edward.
"No way!" Ed exclaimed, "You'll go back to destroying the city if I do! I'm going to hold on to this for a litt-" He was cut off by the stone suddenly dissolving into dust. Both guys stared at the ash.
"Did you just destroy it?" The Freezing Alchemist asked.
"It looks like I did." Ed said confused.
"Oh I guess I forgot to mention that." Truth said. "Because of the conditions you were sent back in if you touch a philosopher stone it will be destroyed."
"What conditions?" Ed asked, "Does it have something to do with Father?"
"I never said anything about conditions." The Freezing Alchemist said confused.
"I don't know if it has anything to do with Father." Truth said, "I'm not the Truth that sent you back here. I can only tell you what I sense."
"Well thanks a lot." Ed muttered.
"What are you talking about?" The Freezing Alchemist said annoyed "You're the one who brought up conditions!" Ed ignored him
"Oh and don't get to cocky about your new abilities." Truth said, "It only works on weak philosopher stones. You won't be able to kill a homunculus with it."
"If I didn't know any better I'd think that you're making it harder for me on purpose!" Ed snarled.
"That's it!" The Freezing Alchemist yelled. "I'm out of here!"
"What's wrong with you?" Ed asked surprised. The Freezing Alchemist glared at him.
"You're crazy!" He spat. Ed stared at him for a few seconds before it dawned on him.
"Oh sorry!" He said, "I wasn't talking to you! I was talking to…um…god." The Freezing Alchemist stared at him long and hard before his shoulders sagged.
"Of course you were." He said sighing, "Anything else I should know?"
"No I think you're good." Ed said. "You took that well."
"This is been a really long day." He grumbled, "If you're a time traveler, them anything could be possible."
"Oh" Ed said. They stood there silently for a few seconds.
"So…" Ed said, "what are you planning on doing now?'
"I don't know." The Freezing Alchemist said dully, "You took out my means of attack so I have no way to fight them now."
"Well look at the bright side." Ed said, "You wouldn't have won anyway. Hey, I have an idea! Why don't you join my side?"
"Join your side?" He asked frowning. "Why would I do that?"
"Well, since I know the future, I know our enemy better then you do." Ed said, "You'll have a better chance at winning if you're on my side. After all, we do have a similar goal." The Freezing Alchemist eyed Ed and sighed.
"I'm going to regret this." He groaned, "Fine."
"Good!" Ed said, "But if you're on my side, you have to do things my way!" Ed said pointing to himself smirking.
"So what's the plan, shrimp?" he said. Ed's eye twitched.
"WHO ARE YOU CALLING A SHRIMP SO SMALL THAT EVEN IF THERE WAS A MILLTION OF THEM, THEY WOULD NOT EQUAL THE SIZE OF A NORMAL HUMAN BEING?! I'M STILL GROWING YOU KNOW!" Ed screamed clapping his hands together and making a giant hand that hit The Freezing Alchemist across the ally.
"You still have a temper I see." The Freezing Alchemist groaned from the ground.
"Yea, and you'll do well to remember it!" Ed said, "Now let's go find a place to stay where we won't get caught."
