Tessa Gray's heart was thumping wildly in her chest, the pulse in her ears building to a deafening crescendo. She knew it was irrational. William Herondale was a skilled and lethal fighter. Charging into battle without goodbyes, without second thoughts, was what he did. He and Jem had told Tessa as much before she knew much about the Shadowhunting world.

They were going to come back. Alive.

Still, Tessa could not slow her dwelling thoughts. They raced by her, as quickly as Will on horseback. Madam Barlow was known for being cunning and sly. It had been said that she could literally evaporate before one's eyes. Were the Shadowhunters really that skilled?

Tessa shook herself. Of course they were! She had seen them in action, seen Will, Jem, and Charlotte slice into their quarry without a moment's hesitation.

Sitting by herself in one of the several corridors of the London Institute, Tessa had never remembered feeling so hollow. Not when Nate had disowned her, not when Jessamine had been killed. Perhaps it was selfish of her to be so worried, but she could not dodge the feeling that something bad was going to happen. She and Will had been in the middle of a horrid argument when they had been interrupted by the call of duty. What if he didn't return? She would never feel his gentle caresses, nor would she ever be able to hear him say again that he loves her.

It was all too much for Tessa. She inhaled deeply, trying to gather herself, and, gently tugging on the tapestry hanging above her for an aid, she got to her feet and marched to her bedroom. Without knowing why, she slammed the door behind her. She went to her vanity, where the mahogany jewelry box that Will had given her sat, and searched for the object that she had long since stopped seeking comfort from. There were several beautiful pieces of jewelry; pearl earrings, golden necklaces, elaborate rings that Charlotte, Jem, and Will had all given to her jumped out at her as she sifted through. Finally, though, she pulled out what she was looking for.

Her little clockwork angel.

As she reached around her neck to clasp the old necklace, she heard her door slowly creak open. Tessa paused. She turned slowly and was swarmed with joy as she was greeted with an arrogant smirk and a wonderfully beautiful man with hair the color of midnight and eyes as blue as the ripping waves of an ocean.

Will smiled at her, her heart lightening. Before she even realized what she was doing, she ran into his arms and embraced him as if she would never let go. He returned her embrace just as tightly, resting his face in her hair the way that he always had.

"I thought…" she mumbled, barely able to contain the small cry of joy that escaped her lips. Will pushed her away gently and held her at arms length. "Must you have such little faith in my abilities?" he asked her, but the smile was still in place. "It was simple. Quick. It always is when I know that I have something—somebody—to return to."

"I love you," she breathed.

There were scarce words exchanged after that, as he pressed his lips to hers. The hollowness that had formed had vanished, as if it were never there. Tessa remembered a time when she had felt foreign at the London Institute, like an alien. She hadn't been able to accept her gift and the world it originated from.

Now, after two years passed, she could not picture herself anywhere else, in any other world. With any usual people. The Institute, Jem, Charlotte, Henry. Will. They were her home.

This is absolutely a one shot. I just had to write something about Will and Tessa because, and I'm not sure anybody can believe this, I love them more than Jace and Clary. Seeing as the setting of the Infernal Devices is in London and takes place in 1878, I know that I could never write a full story about them. But I had to write something.

Kind of iffy on the mid-Victorian era I tried to portray, but I still thought it was cute and fluffy

Review and tell me what you think, and you may just get more one shots of my favorite couple!

Oh, and a quick note, if you haven't noticed in the end I said that two years had passed. Therefore, there are some vague regards to thinks that had never happened in Clockwork Angel, and things that you were probably just like "Huh?" But no, this doesn't take place directly after that story, obviously. So, they are in love and there is nothing significantly wrong with their relationship!
