TMI future

William and Charlotte.

Hi Clary! I hope you arrive soon! Don't worry too much about the kids. We found tracks that can help us find them.
When you told me that Izzy was pregnant, I had to be honest. I am too.
Don't worry about me and the stress. Jem is with me. Just concentrate your attention on the kids and Alec.
Well, finally, I hope he is okay. See you soon, I hope.
Tessa Gray

A lot of months later...

Jace's pov

Jace looked at the photo. His son was on it, drawing a green duck. Jace would probably be mad, but right now, he was too exhausted to be anything.
When he arrived to Idris, his first thought was about his family. He wanted to go back to New-York. But he couldn't. Now, all his thought was about his parabatai.
He stood up. His hand touched Alec's, and sadness came. He wanted Alec back so bad, he couldn't sleep, eat, think. He didn't wake up three days later like Jia had told him. Hour after hour, Jace stress growing into him.
Suddenly, Alec's voice rose.
-You thinking about me?
Jace nearly fell.
-Alec? Oh, Alec. I was so worried. I thought you would die. And it is all my fault. I should have helped you. But I was with Jonathan. It is all my fault...
-No. It's mine. When we saw Jonathan, we went to him. And when he started talking about him being a Shadowhunter, I turned around and left. It was too much. Him, Max, you.
-Me?
-Yes. When you were with him at the Burren Battle. And the month where you were with him, traveling. It was like you died.
Jace nodded. Alec was right. He wasn't himself.
-Well, Alec, I'm glad you're back. I'm calling Izzy. And your mother. (Robert left to stay in Idris permanently)
Jace turned and started walking. He needed Magnus to do the fire message to Maryse. But he froze and looked at Alec again.
-I forgot. Clary said she had news. So when I'm finish, I'll call her. I think it's big news. She left to Idris with Simon, Maia and Bat. She didn't say when she is coming back.
-Ok. I will wait here.

Jem's pov

He went in library. A portal was already there, ready to be used. Clary, Simon, Bat and Maia will soon come through.
The portal was red, a sign that Clary did it. All her portals were red and shinny. But not as shinny as Magnus, who was bright like the sun.
Then, a flash came. Him, on a bed, Will beside him. Magnus was behind Will and they were talking about Tessa, how to rescue her. How to save her.
This flash came with the thought of Magnus. How long it has been since he last saw him? Maybe... When Magnus went to London to help James Herondale?
Without knowing, Jem broke a glass. He was too deep in his thoughts. It happened when he thought about Will. But he had no reason to be sad. Yes, he was his parabatai. His brother. But Will lived a full life. He had kids. A beautiful wife that loved him. He had a big family. Was an Institut director. And died peacefully.
He went to the ground to take the pieces of the broken glass. A shadow on the ground told him that somebody just walked in.
-I... I'm sorry. I didn't...
A pat on the shoulder reassured him.
-It's okay, honey. What were you thinking about?
It was Tessa.
-Will.
Her eyes were now full with sadness. It was always sad to talk about Will. Even after the opposite reasons he just gave himself. He was such a wonderful person. Kind, caring.
Suddenly, Tessa bent down with a cry.
-Tessa! Tessa!
She looked... Strange. And red. Like, tomato red.
-The baby. He is coming!
-But it's too soon... He is suppose to come in at least one month!
-I KNOW!
Suddenly, there was a loud sound. It was Clary, Simon, Maia and Bat. They came in a run, all falling one by one because of the portal. Clary was the first one to stand up. She saw Tessa and ran to her.
-What's happening?
-The baby. The baby is happening.

The most weird in all that was that Tessa was a witch, Jem a Shadowhunter, and they still went to a mundane hospital. Of course, Catarina Loss was working in that hospital.
They went directly to the emergency section. Tessa gave a cry.
A warlock who had red hair and white wings went to see them. He was a doctor. But with powers. Exactly what they needed.
-Hi. Is she pregnant?
-Yes! She is having her baby, Clary answered.
The warlock took her to a rolling chair. Then, they went to a room so Tessa could rest. Until she had finally the baby.

After a lot of hours

Jem's pov

Tessa gave her last cry. Suddenly, Jem heard a baby cry. The doctor gave the baby to Tessa. No. Not one baby. Two. Jem went beside her.
-A boy, the doctor announced. And a girl.
-How are you going to name him, Clary asked. And her?
Jem and Tessa looked at each other. They were smiling.
-William. William Henry Carstairs. (If you have read the Infernal Devices, you should know why I, or Jem and Tessa, picked those names.)
-Why?
-So that there is a new Will with us. A new Will to make us smile and happy.
-And the girl, Clary asked again.
-Clary. Meet Charlotte Clarissa Carstairs.

Hi Izzy!
I miss you! Tessa just had her baby. Or should I say "babies". Its twins. A boy and a girl. I will let Tessa tell you the names. And don't worry, they are very cute.
I hate that I can't call you to tell you everything. But, hey, it's the charm of Idris! And we love our city like that.
Also, I wanted to tell you that we haven't found the kids. With Tessa giving hers, we haven't had the time. But it is still our first goal.
I wanted to know. Is Alec awake? We miss him and Jace.
Hope you come soon,

Clary
