So it's been a while and I'm sorry. I just had a hard time thinking about what was going to happen next. This isn't a real long chapter, but I hope you like it. Disclaimer: I don't own TMI or the characters.

Simon and Isabelle were walking in the school's parking lot, hand in hand, when he asked her, "How about another date tonight?"

"Yes, of course! What will we be doing?"

"It's a surprise."

"Come on, that's not fair. Please tell me." She gave him puppy dog eyes right before she kissed him. He was about to give in when they heard yelling from the other side of the parking lot. "Oh my God! That's Jace!" Izzy tried to run to her brother, but Simon held her back.

"Look, Clary's taking him inside, we'll follow them and see if he's alright."

"Okay." They followed Clary and Jace into the school and saw them walk into the nurse's office. "I think they're having a private chat," Izzy said. Her and Simon stood outside the room and heard everything that was said. When the talking stopped Clary came out of the room and accidentally ran into Simon.

He grabbed her shoulders and forced her chin up, revealing the tears streaming down her face. "Hey, are you alright?"

She shook her head and hugged him, crying into his chest. "You stay here with her, I'll go check on Jace," Izzy said right before she went into the room. When she saw Jace, she looked at his face and sighed.

"If you're here to lecture me, I'm not in the mood," he said to his sister.

"Tell me, did you at least try to protect her?"

"Ah, so you were eavesdropping."

"Answer the question. Did you try to protect her?"
"Yes, I tried back in eighth grade and if I have to do it again, I would."

"I've never seen you like this?"

"Like what?"

"In love."

"What are you talking about, Iz?"

"Don't play stupid. You've never gave any of the girls you sleep with a second look, let alone care for them. But with Clary, you're different. It's written all over your face that you love her so don't deny it, at least not to me."

"What does it matter how I feel about her?"

"It matters because she feels the same way. Trust me. The same look you give her when she isn't looking, she gives you when you aren't looking."

"Iz, I have to get her back. I miss her."

"I'll tell you what, I'll help you get her back. But you have to promise me that you won't be you."

"What the hell does that mean?"

"It means that you can't be a jackass who sleeps around anymore."

"Why would you help me?"

"Because I believe that you believe that what you did back then was to help here. And because I still want my double wedding."

"You know I love you right?"

"I know." She lightly kissed his cheek as the nurse came in and the bell rang. When she walked out of the room, Simon and Clary were no where in sight, but she knew that they were already in class. As Izzy walked to her first class of the day, she came up with a plan to get Jace and Clary back together.

So this was mostly a brother and sister moment, with a tiny little bit of Sizzy. Any questions or suggestions, just comment. Thanks for reading!
