CLOCKWORK PRINCESS SPOILERS. SPOILER ALERT. MINOR CITY OF GLASS AND CITY OF LOST SOULS SPOILERS.

THIS STORY IS REALLY CALLED 'THE LAST TWO HERONDALES' BUT I DIDN'T WANT TO PUT THAT AS THE TITLE FOR THOSE WHO HAVEN'T READ CP2 YET.

Author Notes: This is part one of two. The first part is not one of the best things I've ever written by far but hopefully you enjoy it. I haven't posted in quite a few days with Easter and all, so I decided I'd better hurry up and post this. The second part will hopefully be up tomorrow and it will also hopefully be much better than this one. I just kind of felt a part one was necessary to explain what's going on with Jace.

There is no Wessa or Jessa in this. It's simply a fanfiction that revolves around Tessa and Jace, the two remaining Herondales' and takes place after the war in City of Heavenly and before the epilogue of Clockwork Princess. I hope you like it! Please read and review! :)

Tessa had stared death in the eyes more times than she would have liked to admit but at that moment, staring into those eyes was worse than staring into death's. At least you could anticipate what would happen next with death - with the yellow eyes she was staring into, it was anyone's bet on what could happen.

The feeling of shock she felt when she first came face-to-face with her opponent startled her into silence. A million and one emotions surged through her small frame, with the most prominent easily being dread.

She was well aware that toying with fate never got you anywhere but she could not help but narrow her grey eyes at ones in front of her. When she finally regained the ability to speak she found herself choking out a string of words in a cold and menacing voice. "Out of all the bloody things from my past that could have survived to haunt me in the future, why did it have to be you?"

The words were demanding despite the fact she knew her opposer was not able to answer her.

Her mind was too wrapped up in glaring at the beast, that sat proudly in front of her, that she did not realize that someone had slipped into the room behind her. She would have remained arrogant to the fact that she was not alone if the new incomer had not spoken and made himself known.

"Antagonizing the cat, Tessa? Don't you think you're a bit too old for that?" The familiar voice said. Although his words were accompanied by a chuckle, he sounded drained and dismayed.

If it had been anyone but Magnus Bane, Tessa would have stuttered some sort of excuse to hide her humiliation at being caught. Fortunately, it was him and Tessa knew that if anyone could understand her resentment towards the cat that had stalked her during the dark-nights at the London Institute, it would of been him.

Tessa instantly straightened and turned towards the entrant upon hearing the words, her mind switching quickly to a defensive mode. "That is far from a plain old cat, Magnus! It much more closely represents a demon in a cat costume. What I want to know, is how could that thing survive over a hundred years?" As she spoke, she pointed harshly at Church, who had put on the innocent facade of licking his paw, as if he had not just been planning on attacking Tessa only moments before.

The sparkling warlock gave a simple roll of his eyes and came to give Tessa a friendly and welcoming hug. As they pulled away from one and the other, Tessa surveyed her companions timeless face. Although she knew it was not physically possible, he somehow looked older than he had the last time she had seen him, though she knew it could be easily blamed on the lack of sleep he had certainly been having. Realizing that something must be severely wrong Tessa put on her serious face, forgetting that her question had remained unanswered, said, "Enough of the fun and games. When you called me, you said something was wrong and that you needed me here, at the New York Institute, right away. Now that I am here, what can I do for you?" After pausing for a breath, she added, "Alexander is fine, correct?"

Magnus gave her a small smile. "Alec is fine, my dear, but thank-you for your concern. I actually called you here because of his parabati, Jace." He paused to watch her reaction to the word that had once described the only two men she had ever loved but she only slightly stiffened. He offered her a comforting smile before continuing. "Over the past year, Jace has been through so much. He's been on the brink of death, been possessed by Lilith, consumed in heavenly fire (and I'm sure you remember how that feels), suffered the death of the man he had once considered his father and his younger brother, and finally, had his identity ripped from him multiple times. However, from the first moment things started crashing down around him, he never had the chance to just sit down and recover from everything he has been through. Now, that there is no enemy to destroy and no world that needs to be saving, he has no choice but to think about everything that has happened. It's destroying his sanity and the worst of it is, he has no idea who he is."

Tessa listened intently as Magnus spoke, hanging onto his every word. Her heart ached for the boy who she didn't even know. She understood all too well most of what Magnus was saying, but two questions stood out in her mind. "What do you mean, 'he has no idea who he is'? And what do you think I could possibly do to help him?"

"He grew up thinking he was Jonathon Christopher Wayland. Several months ago, Valentine convinced him that he was truly a Morgenstern. During the war, he found out that both names were just a lie and that his true name was Herondale," Magnus said simply, as if he was not dropping a huge bomb on his oldest friend's head.

The shape-shifter's eyes went wide and she let out an involuntary gasp. "If he's truly a Herondale that means…" she let her voice trail off, unable to continue her sentence as the realization dawned upon her.

Magnus nodded. "It means that he's your great-great-great-grandson who is desperately in need of some familial help. He's broken with grief and confusion, and if do remember correctly, if you have quite a knack for fixing broken Herondale boys." He said the words as softly as he could but they still managed to pierce her heart in the painful way only the mention of Will could ever do so.

It was at that moment Tessa realized why Magnus had summoned her to the institute in the first place.

"You want me to fix him."

It wasn't a question.
