My heart ached and my mind was hazy. Tom was gone, and it was because of me. If I hadn't proposed a walk through the forest, he would still be in his room, safe and sound.

Staring at the wall in front of me, I sighed and faced Grindelwald who sat behind his desk.

''We can't just wait, can we? It's torture!''

He nodded and tried to calm me down. ''He'll be OK. I'm sure,'' he said.

''What are you talking about? How can you be sure?'' Tears streamed down my face and I looked down at my hands.

I needed to contain my anger and emotions. This was not something to just cry about and hope for the best. I needed to help my little brother. If wouldn't, it would drive me crazy.

''I can't. But Tom is a special boy. He'll find a way to survive.'' I started shaking my head and sobbed.

''He's just a boy,'' I choked. Grindelwald watched me sadly and approached me to embrace me tightly.

He tried to tell me what he felt but failed. ''I know this is hard, but Tom is strong.''

''Just like you,'' he said, tightening his grip.

We were startled by soft ticks on the window. I looked over his shoulder and saw the black raven sitting on the ledge. I quickly approached it and noticed a piece of parchment in its beak.

I clumsily opened the window and the bird hopped onto the window sill. I stared at it as it dropped the note on the ground. Then it took off again, and I watched it soar away.

I ignored the open window and took the parchment from the ground.

Keeping secrets from your little brother now, are we?

If you want your life to include Tom, you should come to the lake at dawn. Come alone and don't you dare take someone with you, they'll die as soon as I lay eyes on them.

If you won't do as I say, you can wave bye-bye to your little Tommy.

I stared at it in hopelessness.

Grindelwald took it and quickly scanned the message.

I couldn't go. It was obviously a trap. But I needed to save Tom. He was my brother.

He sighed frustrated and looked outside angrily. ''That damn bastard wants a fight? Then that's what he'll get.''

I looked at him and shook my head with tears in my eyes. ''It's a trap. You'll die,'' I mumbled softly.

His expression softened and he took my hand. ''Of course, I won't die. Don't worry. Nevertheless, I want you to stay here, it's too dangerous for you to come. I don't want anything to happen to you again.''

Now I grew angry. ''I won't let you go without me. They want me to come, and nobody else. If you come along, you'll die. That's what it says!''

He shook his head. ''I won't die. The Ministry couldn't hold me, so neither will he. Trust me,'' he said softly.

I looked into his eyes and knew that arguing wouldn't work. I wouldn't win it from him.

''Fine. I'll stay here,'' I said controlling the anger that was still boiling inside of me.

''Don't worry.'' He pulled me into a hug and knew nothing of what was going to happen that night.

This must be the night of the prediction. He was going to die and I needed to save him.

He believed me when I told him I was staying at Nurmengard. But what he didn't know was that I would be there even before he came.

I had planned everything out and I was confident that everything was going to go as I wanted it to go.

Grindelwald was getting ready to go to the lake and was in his office making the last few preparations. I knew he was coming to see me and say goodbye before he went, so I waited for him to come before I left.

I quickly took the potion from the drawer and put it in the pocket of my cloak.

I was mentally preparing myself to face the upcoming events. If something went wrong I would lose another person, maybe even two.

I now knew who the cloaked man was. And now, all the pieces of the puzzle fit. This was my final chance to change the future and I was going to make sure it would happen my way.

The door opened and I looked up at Grindelwald who stood there looking at me with a small smile.

I returned the smile and stood up to receive his hug. ''Good luck,'' I whispered softly. If I was going to trick him, I'd better do it right.

He placed a kiss on my cheek and nodded. ''Don't worry. I'll be back soon.''

My breath hitched slightly and I smiled nervously. I watched him leave the room and waited for his footsteps to fade away. Then I took a deep breath, checked the potion in my pocket and made my way out of the castle.

Once I was outside, I checked my surroundings and disapparated.

When I arrived next to the frozen lake, I quickly went to the surrounding bushes and hid behind them.

I waited several minutes, gazing through the leaves of the bushes at the clearing in front of me.

I was about to shift so I'd sit more comfortably when I saw someone walking near the lake. Dark cloaked, he walked near the water. Again, he was wearing the hood and I wondered why.

I breathed softly, afraid he might notice me. I felt anxious and excited. I knew what was about to happen, but I also knew I could prevent it from happening, and the adrenaline surging through my body caused me to start trembling.

I stared at the man, waiting anxiously for Grindelwald to appear.

Once he was there, everything depended on me. If I made a single mistake, everything would be lost.

I felt the pressure rising and hoped he would come soon especially since my legs were starting to cramp.

I heard a screech and the dark raven appeared from the sky. It descended towards a single tree that stood in the clearing.

I watched it intently and watched the cloaked man nod at it.

Then Grindelwald appeared and strode across the clearing holding out his wand and looking around with a dangerous look.

His gaze fell on the cloaked man and he pointed his wand at him.

The man had his back turned to him and slowly turned around, a smirk plastered on his face.

''Well, if it isn't the great Gellert Grindelwald,'' he said. His voice was low, almost a grumble. He spoke softly which is why I had to strain to hear what he was saying.

I eyed the raven suspiciously. Something wasn't right about it.

''Return Tom to us,'' Grindelwald replied dangerously.

The raven turned into my direction and I felt its gaze on me. I ignored it and watched the scene.

''And why would I do that?'' the man asked raising his eyebrows.

Before anyone could blink, dazzling red light erupted from the tip of Grindelwald's wand and hit the man. He fell down and writhed for a second before he looked up and grinned again.

''It's a good thing that this isn't a way to persuade me.''

He took his own wand and shot a curse which Grindelwald dodged with ease. ''Tell me where he is. Now,'' he growled stepping closer to the man and sending another Cruciatus Curse at him.

Suddenly the man started chuckling and got up, clutching his chest. ''You may be strong as an individual. But every man has weaknesses, even you.''

Grindelwald hesitated curtly. ''I don't have any weaknesses,'' he said, before sending another curse at him which caused him to tumble again.

''You'll get what I mean soon,'' the man said gasping for air.

I caught movement from the corner of my eye and saw the raven slowly turning into a man. Its beak vanished and the feathery wings slowly turned into arms.

I gasped when I realized it was Jonathan and he had his wand aimed at Grindelwald's back.

As a reflex, I jumped up and shouted at Grindelwald to watch out. Everyone turned their heads to me, and I saw Jonathan and the cloaked man grinning.

Grindelwald watched me hopelessly and looked back at the cloaked man.

''Your weakness, is her.'' He pointed towards me and I shot a curse at him. Before I turned to Jonathan who jumped down from the tree and ran into the woods. Slowly turning into a raven again.

''She's the one for who you'd do anything. And that's exactly what we need.''

Grindelwald watched the man angrily and I looked at him with a guilty look. I didn't want him to find out, I just wanted him to survive.

Nobody had expected the cloaked man to be as quick as lightning and he had shot a curse at Grindelwald who at that point, had been distracted and was looking at me.

He looked at me with wide eyes and slowly fell to his knees. He seemed to be having trouble to breathe and he slowly fell back into the snow, dropping his wand.

I looked at the cloaked man and made an attempt to curse him but he was quicker. He flicked his wand several times, his eyes flickering.

I gasped and felt deep cuts form on my arms, legs, chest and shoulders.

I fell down and watched the man approach me with little interest showing on his face.

''You should've learned by now, that you don't deserve a happy ending. After everything that's happened to you. Why didn't you just give up?''

I glared up at him, clutching my arm. ''Because I'm a survivor.''
