Hello everyone! Please bring your tissue because I mixed an AU with CoG situation. (I will) Enjoy (your tears). Unbetaed. All mistake is mine.

This week prompt. "where everything is black and white until you meet your soulmate. when your soulmate dies, the world goes back to black and white au." Take liberty as usual and using CoG. (AKA PREPARE TISSUE GUYS PLEASE)

For a long time, colour was never in his life.

While most people had found their soulmates in their teenage years or early twenties, Theseus hadn't. It resulted in him spent most of his life without colours. Through his life, people always mentioned about colours that they could finally see after meeting their soulmates. Whether it was his parents, his friends from Hogwarts, his fellow soldiers, or his colleagues. Theseus didn't understand their fondness and fascination with colours since he didn't know it from the beginning. He could live his life just fine without it after all.

There was this fascinating question someone asked him about colours.

Won't you miss the colours?

How Theseus supposed to miss it if he never introduced to it. He was so amused by that question that he just laughed when a soldier under his command asked him that. He told that soldier that he won't miss something that he never met. When that soldier asked again that would he like to see it one day, he didn't answer him. He simply shrugged and told him to prepare the troops. He had indirectly dismissed the soldier. Without words, that soldier left him alone.

When the soldier left Theseus gave out a long sigh. It was not in his priority when the world was going to an end because the higher-up in the muggles community decided to go for war around the world and involving innocent people who were not part of it.

And with wizarding communities decided it was not their jobs to stopped a muggle war, Theseus had taken the matter on his own. Because he knew to leave people -innocent people- regardless they were wizards or muggles, was never the right thing.

Theseus just had to do something even though it would kill him inside.

The thought of wanted to see colours, essentially meeting his soulmates never crossed his mind when Theseus fought in the war. All he could focus on was how to stop the war because the body counts were already too much. He just wanted it to stop.

By near the end of the war, Theseus was already so worn out and the Ministries only decide to interfere now when there were already damage to the wizarding communities. He couldn't help but feel bitter about it because they only listened by near the end war and even involved his only brother, Newt Scamander, to train the dragon, the Ukranian Ironbellies, in the eastern front.

The accident in regard to that project only left the bridge between Newt and him burned. He didn't even know how to approach him again even though he knew he would keep trying to stay in contact. Despite Newt would probably ignore him for times being.

The war came to an end and people regarded him as a War Hero.

And Theseus hated it.

War Hero.

Theseus couldn't help but chuckles in frustration at those words. What he had done was nothing heroic per se. In the end, he killed people even though he hated the war. The enemies he killed were also people, some of them became a soldier because they were forced by their countries. There was nothing heroic about the whole things. It was all one big systematic killing. War Hero was nothing more than a fancy name for a murderer. That all he ever was.

And he hated himself for that.

Theseus kept busying himself and running only with liquor and coffee. He was too afraid to sleep most of the time because the nightmares that haunted him. He didn't want it to happen so he ended up avoid sleeping altogether. He wondered sometimes how he was still functional afterwards and how people manage being fooled by his act.

Theseus came to a conclusion; it was because, in the end, he was never really close to anyone. No close friends, mostly colleagues. No people who he could trust to confide with. And there were this whispers of his demon that he wished could turn his off. He was slowly losing any semblance of sanity he barely holds.

And that was when the colours finally entered his life.

That she entered his life.

At that time he was called by Travers to his office to talk about his current promotion as Head of Auror Department and how they were going to operate from now on. She knocked on the door of Traver's office and there was a sound of a door opened and followed by clicks of heels. He turned his head to see who came.

And their eyes met.

Both of them were startled because there was a sudden onslaught of colours entered their sight. She took a step back and he kept watching her in shock. None of them reacted, loss of words what to say. Their eyes didn't leave each other kept staring on each other. He couldn't help but notice that she had such beautiful eyes. He was not sure what the name of the colour but it was beautiful and warm.

Travers cleared his throat and told him to stop staring at her. He then introduced her to Theseus. Her name was Leta Lestrange and apparently was an investigator and also Travers's secretary. He was fairly surprised when Travers told him what her name was.

Theseus recognised that name from the letters used to send in his Hogwarts days and from the rumours in the wizarding community. She was Newt's friend until the expulsion that damaged their friendship. And at the same time, she also the daughter of the Lestrange that kept being talked.

Theseus never really paid attention to those words because he thought despite everything he should try to get to know the person first before put his decision about someone. That was only fair. Also, someone that could make Newt want to befriend and protect, must be good enough at least. His little brother would not just befriend anyone after all.

So for the rest of the meeting with Travers, Theseus couldn't stop stealing glances at Miss Lestrange. He wanted to talk to her and for the first time in a while, he was feeling excited. It had been sometime he felt something outside of numb and tiredness. Something that made him felt alive. He never knew met a soulmate would feel like this. He wondered was this feeling that people around him tried to tell him.

When the meeting finished and both of them already outside. They stared at each other, not sure what to say and at the loss of words. There were things they need to talk about. He was going to ask her to have dinner together but for some reason his ability to talk smoothly gone because every attempt he was going to say something, the words stuck in his throat. After several attempts, he finally managed to ask her.

"What do you think of having dinner together, Miss Lestrange?"

Miss Lestrange blinked at him repeatedly and then started to chuckles. "Is it alright?"

"What do you mean?" Theseus asked again, confused.

"You recognised my name when Travers introduced me, Mr. Scamander." Miss Lestrange pointed out. "And knowing my family reputation I am not sure it was a good thing." She smiled at him sadly. "I am sorry your soulmate has to be me."

Theseus tilted his head and stared directly at her eyes. "I recognised you from Newt's letter first and foremost." She startled by his words. "And about your family reputation. Rumours within the wizarding communities couldn't always be trusted. I am going to judge what kind of person you are with my own eyes not based people words." She still looked at him with disbelief that he promptly gave her a reassuring smile. "Also someone that Newt protected won't be such a bad person. I am sure of it, Miss Lestrange."

Miss Lestrange opened her mouth but then closed it. Instead, she shook her head and chuckles. "You are such an interesting, Mr. Scamander."

"I considered it a compliment, Miss Lestrange." Theseus smiled. "Also call me Theseus. I don't want you to call me in such a formal way. It's strange to hear somehow."

"Alright, Theseus." Miss Lestrange agreed. Theseus absentmindedly noticed that he liked the way she said his name. "But then you also have to call me Leta." She smiled.

"Sounds good." Theseus grinned. "So what do you think of the dinner, Leta? I am starving."

"If you would have me, Theseus." Leta smiled brightly.

Theseus could feel his heart skip a bit at her smile. "That will be my pleasure, Leta."

The dinner went well. They clicked almost too easily. Theseus told her stories of his misadventure when he was young and when he just became an Auror. Leta listened to him carefully and laughed when he exaggerated some part of the stories. Then they talked about their hobbies, daily activities and almost anything that came up in conversation. If there one thing he was sure of it was that he loved hearing her laugh and seeing her smile. He wondered what kind of feeling he felt right now.

Theseus won't call it love yet but the feeling he felt make him happy. It felt like waking up from a long nightmare. He wondered if this what his parents mean when they said meeting soulmate would make someone's life were more colourful.

After talked about how they were going about the relationship, they decided to meet up every lunch and tried to hang out together at the weekend. There would be days he won't able to meet her because an operation that taken on but that was why times he could meet her always felt more specials. He loved it. For some reason, he could breathe a little bit easier, could laugh more freely and found the world more beautiful than before.

It was all because Leta Lestrange entered his life.

But there were also side he was scared to show her. That broken side of him that he didn't want to show anyone because that wouldn't be anyone expected him to be. He was scared if he showed him that side of him, she would look at him with disgust and pity. He didn't want to that to happen.

And Leta proved him wrong.

It was when of his bad days. He couldn't hide nor control his emotions. The nightmare and the whispers of his demon distracted him badly that he had to call off work and stayed in his house. He was so distraught and pulled knees up, burying his head on it that he didn't hear her coming until she called his name.

"Thes?"

Theseus looked up to found Leta was in his room. He couldn't comprehend because why would she be here. His mind was confused. Leta noticed it and explaining it to him as she sat on the bedside.

"I know you called off work. I was worried because you never called a day off before and the feeling sometimes I feel on you, feel much stronger than usual. I decided to leave early a visit you and surprised to find your house was dark. And it was locked." Leta showed a copy of the key to his house. "Fortunately, you gave me a copy of your key or I had to find a way to cast away your house protection." She chuckled a bit before threw him a concerned gaze. "You looked awful and I can feel you are unsettled. What happened?"

Theseus didn't know what to say because how to explain the condition he had been fighting off all this time. About his nightmare and his experience in war.

And that he was nothing but a murderer.

Theseus didn't know where he found the courage but he told her about all of it. Leta listened to him as he told her his stories; words rolling out from his mouth easier than he thought possible. But at the end of his story, he didn't dare to look. He was scared of what he would see in her eyes.

"Theseus," Leta whispered. "Please look at me."

Theseus reluctantly raised his head, his eyes widened as his eyes met with Leta's. There was no disgust or pity in her eyes. Instead, there was sadness and understanding. And something more that he couldn't recognise yet. There was relief that washed him over that it made him feel much better before.

Without words, Leta pulled him into her arms and whispered against his ears. "It must be hard for you. Hiding all your problem and feeling deep inside without letting anyone know about it. I know that feeling. I am so sorry, Theseus." He could feel she tightened her arms around him, as he tried to hold him together. "I will never let you alone anymore."

And tears dropped from his eyes just like that.

Leta let him cry with all his might, letting the feeling that buried within him go and never let go of him at the same time. She whispered comforting words and told him it was okay. That she would always be there for him.

That day was the first time she spent the night at his house. It was also the first time he felt well-rested in a long while. He was woken up with Leta's face in front of him and he found himself to smile at such sight.

The sunlight that managed went through curtain fell on her brown skin and hair. He wouldn't able to appreciate Leta's beauty much more if he couldn't see the colours. She was very beautiful. He caressed her cheek tenderly with her backhand.

Leta was woken up by his action. She was blinked sleepily at first, didn't recognise where she actually was but then realisation dawned her. She smiled coyly at him. "Do you like what you see, Thes?"

"Very much, Leta." Theseus answered. He got closer to her and nuzzled her which made her laugh in happiness.

As he thought, Leta's laughter really was the best sound in this world.

Ever since that, their relationship progressing faster. Not long after, they became a girlfriend and boyfriend. Theseus noticed there was a time that Leta would make an expression that he saw in his reflection and sometime she would wake up by nightmare when she slept in his house. She didn't say what was her nightmare but he knew it was haunting her like how his memories of war haunting him. But he won't force her to say anything. If she were going to tell him, she would.

That was why instead Theseus focused on how to make her feel safe with him. If Leta felt safe, one day she would tell him in her own time. He believed that. He let her vent about her days to him, teased her, made funny jokes and cooked her favourite foods without magic. Leta showed him various expression but in the end, his favourite would always be the bright smile that would blossom on her face whenever he made her happy.

Theseus always considered it as a blessing.

It didn't take him a long time to propose to Leta. Theseus was rather scared to be rejected but when Leta gave him a big, watery smile and say yes. He immediately gathered her in his arms and thanked her to allow him to be her husband which she responded it should be her that grateful to be loved by him. He promised he would make her the happiest woman in the world.

Leta laughed and said. "If it were you, I could believe it, Thes."

"Thank you for your trust, darling." Theseus said softly.

After their engagement, for some reason they also capable to communicate and sense each other via their bond. According to his parents, it would only happen once their relationship was strong and Theseus was so happy to hear that.

Theseus didn't tell any of his colleagues about their engagement but all of his colleagues ended up rather spooked with the way he kept smiling and humming. Also, not only his colleagues even Leta's colleagues were also spooked with her never-ending good mood. It was going on for a week until they noticed his engagement ring.

Needless to say, there was a wave of congratulations to both he and Leta. Some of them were genuinely happy for them but some were only mean it in the front and the rest didn't even try to they were gossiping.

The War Hero and The Outcast.

Theseus snorted when he heard that. Because of course they had to gossip about their love life and gave them such a title as if they were some kind of characters in the story. They were soulmates that find their way and fall in love for real, just like most people were.

Theseus was upset but Leta said he shouldn't be upset over it. Their colleagues would slowly stop talking about them when they found a new thing to talk about. He snorted because he knew it was true. He had just to be patient.

Not long after their engagement, Newt came home. Theseus got words about his fight with Grindelwald who posed as his correspondence in MACUSA. Not only that, the Ministry issued a travel ban for Newt and he had to be the one who delivered the news.

Newt was rather upset about the travel ban and the first thing he asked later how to lifted the ban. And on top of it, before he could tell Newt about his engagement with Leta, she entered his office in a hurry when he about to tell Newt. After explained about it, Newt congratulated them. Newt said he was not upset and he had found his soulmate.

Theseus was about to ask more when Newt excused himself and leave. He and Leta exchanged glances and settled it was because he still felt awkward around them. Theseus really wanted to Newt to be comfortable around them and that was why he kept inviting him for dinner but Newt kept rejecting it.

When Newt invited them to book signing, he was happy because maybe this time around Newt would be more open with them. Theseus also used this chance to asked Newt to be his best man which Newt accepted rather reluctantly.

Theseus wondered whether there was really no hope to make his brother came around them. If it were not for him, at least for Leta. He knew Leta wanted to fix their friendship and seeing her sad like that made him feel sad too.

There were many things happened afterwards that they had no time to talk about their wedding except the fixed date. They were going to be married on June 6th 1928. Even though reluctantly, Newt already accepted to be his best man. But there were more pressing situations not long after.

There were Grindelwald's escape and words about how he gathered his acolytes in Paris. The prophecy about the Lestrange family issues and then, followed by the ball where the rumours were talked about actions that he wished he didn't bring Leta there, found out that the obscurus -Credence Barebone- survived, Leta told him about her secret that she had been holding, Newt's fifth attempt to lift the travel ban, Hogwarts, Dumbledore and then Paris.

It all happened so fast.

And then Theseus led the group of Aurors to slipped in Grindelwald's rally. He glanced around because he felt Leta's presence and he found her. They exchanged a long glance and she promised she would tell him what happened later via their bond. And then Grindelwald called them out Aurors to come down. He could feel it in his gut this was not good. He once again ordered his subordinates to do nothing.

Grindelwald tried to rile up people in the rally and then a situation happened too fast. One of his auror accidentally killed the girl and by then he knew there would be no way to end it without violence.

When Grindelwald used his cursed blue fire to make that surrounded the Amphitheatre and started to attack every single of his subordinates, didn't let them escape. He noticed his brother was there and he almost could feel his heart drop when Grindelwald taunted Newt.

"Mr. Scamander," Grindelwald mocked. "Do you think Dumbledore would mourn for you?"

Theseus immediately stood beside Newt and not a later second, Grindelwald attacked them with the cursed fire. They tried to hold it back until there was a familiar clear voice that stopped Grindelwald from attacking them.

"Grindelwald! Stop!"

Theseus turned toward the source of the voice. His fiance descended slowly from the stairs. He whispered in fear. "Leta." He immediately rushed to her, fending off the cursed fire in his way.

Grindelwald started talking, using his silver tongue to lured her. He tried to tell Leta via their bond that she shouldn't listen to Grindelwald but she didn't respond. He almost could feel his heartbreak when Grindelwald offered his hand and Leta raised her hand to took it. But then, Leta didn't grip Grindelwald's hand and he went back to the circle of curse fire alone.

Theseus was confused and relieved at the same time but that feeling didn't stay for long because Leta turned to him. Her eyes looking past him for a bit then to him. They exchanged gaze that felt so long for him when she said the words followed by the words she told him via their bonds.

"I love you. "

I love you so much, Theseus Scamander. Never doubt that. Live for my part too, promise me.

Leta broke their gaze, pulled her wand and destroyed the skull that held by Grindelwald's lieutenant. The cursed fire started to going rampage, no longer in control of Grindelwald.

"GO!" Leta screamed.

Theseus looked at her direction and not having it. He told her via their bonds.

I WON'T LEAVE YOU, LETA!

Theseus used all his might to reach her, to reach her by time but then Grindelwald killed her. It was as if the time slowed down for him. He saw Leta's body slowly turned into dust and the world of colours slowly turned to be the familiar black and white once again. She turned to him and said her last words via their bond.

I am sorry I couldn't fulfil my promise but you have to live on. Promise.

Theseus barely realised that Newt held him back and disapparated them outside because of the anger and the pain that consumed him. As soon as the cursed fire went wild outside, he reacted fast as his instinct took over. He made sure it won't harm his brother. He won't lose another person that precious to him.

To take down the cursed fire, the few wizards left there made a circle, making sure it won't destroy the city. He and Newt immediately apparated to other side and at the same time put their wands into the earth followed by the cries of Finite.

There were two kinds of fire that fighting each other and he no longer could tell which were the cursed fire and which came from the tip of his wand. When the fire went into the sky, getting extinguished he growled in agony.

After the fire extinguished completely, Theseus lowered down his wand and just breathe. He could barely process everything because there was only one thing that went through his mind.

That Leta was dead.

All Theseus wanted to right there was just crumbled and cried but he didn't because he felt so numb. He only registered that Newt approached him when in the corner of his eyes he saw Newt raised his arms and pulled him into it.

Theseus just sobbed into him. Newt never hugged him on his own and he really needed it right now. He latched onto his coat and gripped to it tightly. Then, Theseus heard Newt whispered.

"I've chosen my side."

Theseus sobbed harder and hugged him tighter. He had his brother back but at what cost.

Theseus knew that in this fight he had lost so many things. He had failed the teams he led and let them killed. And he lost his fiance, the love of his life, Leta Laurena Lestrange. He knew there was part of him that died along with her along with colours in his world. Even though Leta asked him to live for her part too. It was still hurt but he already silently promised. He would live for her part too.

But Theseus knew, he would once again living but not alive.

Because the colour had left his life.
