Wessa what if

Save me

Will POV

"Cecily wait!" She'd disappeared through the door without any signs of fear. Where she got her bravery from, I'll never know. "Cecily I swear-"
I was stopped dead in my tracks by Cecily, stopped and pointing at something I couldn't quite see. As I stepped closer, I saw that there was a figure in the corner of the room, shackled to the wall. Blood was running down her side. Tessa.

I tried to run towards her but Cecily stopped me, I looked at her in confusion. "Look" she whispered. I looked to where she was pointing. Opposite tessa was Satan himself. A small man with a knife in his hand, a sly look on his face. I looked at tessa again, she didn't look terrified at all. And somehow that made me love her even more.

"What do we do?" Cecily whispered.
I tried to think of something; maybe we could storm in, but he'd get to her faster than we would, maybe we could shoot him, but maybe he has backup. I had nothing.

"I don't know Cecy, I don't know"

Tessa POV

Mortmain had been sitting here all day. Watching me. Waiting.

"I won't do it" I spat

"You will, do you know why?"

I shivered, his words making their cold way up my spine.

"You will do it because if you don't, i will kill them."

"Kill who? Like you said I only know my grandfather"

He reached behind him and pulled out some parchment, oh no. No. My drawings, he knew. William Herondale.

"This boy, whoever he is. I will find him, and I will kill him. Along with everyone he loves." He smirked "and I'm sure he hasn't been locked away for 17 years" he turned to walk away, knife still in hand.

I gulped "Fine"

Mortmain turned slowly towards me, "fine what?" He smiled again, making my insides churn

I sigh, all my air escaping me, leaving me breathless and weak.

"Fine. I'll marry you"

Will POV

They spoke forever. As mortmain turned back towards her, I felt the light escape tessa.

"Will what's happening?" Cecily whispered, her own bravery fading

"I don't know cecy" I tried to hush her but I couldn't hear anything, we were too far.

"Wait will, I think he's leaving"
She was right, mortmain was gone. I looked at Tessa again, her head was against the wall, her shoulders moving as though she was sobbing. My heart broke looking at her like that.

"Lets- Cecily?" She was gone, already moving towards Tessa

"Come on will"

Tessa POV

"Uhm excuse me" I jumped in my seat, there was a black haired girl standing in front of me, blue eyes like wills. A shadowhunter.
I quickly wiped my face against my shoulder. "You can't be here, he'll come back. He'll kill you" I whispered, my voice shaking

"We're here to get you out. Don't be scared. Everything's going to be okay. I promise" she picked at my shackles, finally breaking free.

I nodded and sighed. But then, "we?"

As if to answer my question, someone stepped from the shadow. Much too tall to be mortmain. "Will?" I half gasped his name I was so in shock.

He smiled at me and suddenly I forgot where I was. "Tessa, it's okay." I nodded and he picked me up in his arms. I threw my arms around his neck, I had met him once, but I already knew him. I already loved him.
