Simon

When Isabelle was on the phone last night with Clary, I knew what was happening. My little girl was growing up and I didn't know how I felt about that. I loved Will like a son, but that didn't mean that I wanted his hands on my daughter. Seeing them walk into the gym together, holding hands, just about gutted me.

I saw Will walk out of Jace's office and knew I needed to talk to him so I pulled him into my office. When Jace and I became partners in the gym, we added on an office for me. Will sat down in the chair in front of my desk.

"What's up, Uncle Simon…uh…Mr. Lewis," Will stuttered, not knowing what to call me anymore.

"Will, calm down," I said trying to stifle my laughter. "I just want to talk to you." He nodded. "So, I know that you and Tessa are together now."

"Yes, sir." He was wringing his hands in his lap.

"I understand that your parents set some rules and I expect you follow them, especially in my house."

"Yes, sir."

"You know how much I love that girl and I expect you to treat her with respect. She deserves to be loved and treated right."

"Absolutely. I would never think of treating her any less. I love her."

"All right, get back to training." I said, ignoring his last statement. I wasn't ready for that part yet. He hopped up out of the chair with a nod and walked out of my office. I sat back and looked at the framed picture of my family sitting on my desk. Tessa was about three years old in the picture and she was wearing this frilly dress that she absolutely hated.

Isabelle tried so hard to make Tessa wear dresses and do girly things, but finally gave up when she was about five. Tessa always wanted to run with the boys and befriended Will and James early on. I knew she would eventually want to go into MMA, but I tried to hold it off as long as possible. Will started in the kids' class when he was five and Tessa would always sit on the edge of the mat and yell to him what she thought he should do.

Jace and I had talked about Tessa training, endlessly. When she and Will came to us when they were ten and explained that Tessa wanted to start training, I had to let her. She was better than most of the boys she trained with and I wouldn't allow myself to deprive her of her passion. Isabelle was worried when she first started training, but now she couldn't be more proud of our daughter.

When I really thought about it, Tessa and Will being together did make sense. I guess I had known since they were little that they were perfect for each other. Isabelle had been trying to push them together since they were babies, but I knew that if they were meant to be together, they would find a way on their own. I was actually proud of Will for confessing his feelings and I knew he would treat her right.

Next to the picture of my family on my desk was a picture of all three kids playing in the ocean when they were no older than ten. Even then, they had all been attached at the hip. It was a good moment when we all realized that the kids loved each other and we wouldn't really have to worry about them not having anyone. They would always have each other.

Jace came into my office and sat down, bringing me back to reality.

"Hey, man," he said as he sat down in the chair in front of my desk, exactly the way Will had just done. It really amazed me how much they looked alike. "Clary and Iz are bringing lunch, apparently and then they're taking James to some shoot they are doing together."

After Isabelle had Tessa, she put the sports photography on hold and partnered up with Clary to run the studio. They basically did any kind of shoot people wanted. The local high school even had them take some of their yearbook photos for the sports sections.

"Awesome," I said leaning my head back against my chair. "Have you watched them yet?" He knew what I was talking about, but I couldn't bring myself to go out to the main floor and watch Will and Tessa train together.

"Yeah, they were totally going easy on each other earlier. It was pretty adorable." I grimaced and he laughed.

"You don't get it. You have boys so you wouldn't understand what it's like to watch your little girl who used to think you were the only man in her world, snuggle up to some little man child. It sucks."

"Yeah, Will totally is a little man child, but you've known him his whole life. You know he loves her and I feel like if you had to choose someone for her, it would be him."

"Whatever." I rested my head on my folded arms on top of the desk. I heard the door open and Clary and Isabelle came into the office.

"Hey, boys," Clary said as she sat on Jace's lap and kissed him deeply. You would think they were the teenagers in the situation. Isabelle mimicked Clary and sat on my lap, but kissed me lightly. "We brought you food."

I wrapped an arm around Isabelle's waist holding her to me as she set the food out on my desk.

"Have you talked to Tessa," Isabelle asked me as we ate. I shook my head and looked away from her. "They're so cute, Simon. You should see them."

"They're acting the same way they always have you weirdo," Clary said from the other side of the desk.

"Right, but it's different because we know they're together." Isabelle kissed my cheek and ran her hand through my hair. I shook my head and laughed at their antics. When they were on the phone together the night before, I couldn't help but compare them to two gossiping teenagers.

"Well, we should probably get going, Iz," Clary proclaimed as she stood taking Jace's hand and leading him out of the office.

"Yeah, I'll be there in a minute," Isabelle said as she began to clean up our mess from my desk. Clary and Jace exited the office and I pulled Isabelle back down onto my lap. She turned to face me more and captured my lips with hers. She kissed along my jaw before returning to my mouth. Man, I loved her. My wife was perfect in every way. "Hi."

"Hi," I said with a chuckle. "What are you guys going to shoot?"

"It's a baseball game for the school's yearbook. James joined the staff so he's actually the one shooting, but he wanted us to come with him." I nodded as we fell into a comfortable silence. "What are you thinking about?"

"The fact that Tessa is growing up and that she doesn't need me anymore." She kissed my temple and rested her head on my shoulder while running her hand along my spine.

"Simon, Tessa will always need you." I scoffed. "I'm serious. Girls always need their dads; I mean, think about it. Who taught her how to drive? Who protected her at night when she had nightmares? Who sang her to sleep every night? Who taught her how to do a flying armbar? You did."

"I taught her how to do those things, but as soon as she learned how to do them, she ran off with Will."

"Will was her best friend. Of course, she would share things with him and you're not seriously jealous of a sixteen-year old kid, are you?"

"It's stupid, but I am. He's taking her away from me. She's not going to run to me for help anymore or look for comfort in me when she's scared. She's going to go to Will."

"I hardly think he's taking her away from you. She's always gone to Will for comfort, too, and you know that. She used to get so mad at us when she was little and Will would always talk her down. They're sixteen; they're not getting married and they just started dating. They've been best friends their entire lives and I think we all knew this was going to happen eventually."

"I know and I love Will, you know I do, but what if he breaks her heart? That would change everything."

"I know this sounds crazy, but I don't think either of them will break the other's heart. I think they are it for each other and it might take them a while to realize it, but they will end up together in the end." I nodded, knowing she was probably right. Will and Tessa were made for each other; I just hoped they didn't hurt each other along the way. There was a knock on the door and Tessa peeked her head inside the office. "Hi, honey."

"Hi," Tessa said as she came in the office and sat down in the same chair everyone else had sat in. Apparently, my office was a popular hang out spot today. "Can I talk to you guys?"

"Of course, what's up," I asked as Isabelle got up off of my lap and stood behind me.

"Well, Will and I wanted to go out to dinner tonight, like a date, but I just wanted to make sure it was okay with you first."

"Like a real date," Isabelle asked and I knew she was trying to stop herself from clapping like a small child.

"Yeah, like he's going to pick me up at the house and we'll actually go out to dinner, just the two of us."

"I don't have a problem with it, as long as you're home at a decent hour," I said as I tried to put on a supportive smile.

"Thanks, Dad." She came around the desk and wrapped her arms around me. I just had to accept the fact that my little girl was growing up. It wouldn't be easy, but Jace was right, if I had to choose someone to be my daughter's first boyfriend, it would be Will. I would definitely have some fun with him, though.

Isabelle kissed me goodbye before following Tessa out of the office. I took another minute to sit there before I went out to the main floor to do my portion of training for the day. When I walked out of my office, I saw Will and Tessa sitting cross-legged, facing each other on the mat. I whistled loudly, pulling them apart before I rattled off instructions for a circuit workout.

I loved training these people. There is nothing more gratifying than helping people achieve something they're passionate about. Watching a kid master a skill they've been working on for weeks is why I partnered up with Jace in the first place.

After an hour, we were finally done training for the day and I could go home to my wife. I watched Tessa and Will walk out of the gym hand in hand and realized that Will was looking at Tessa the same way I looked at Isabelle. How could I blame him for falling in love with her? She was her mother's daughter and she made it so easy to love her. Will kissed her lightly on the cheek and I respected that he didn't maul her in front of me. As he got in passenger seat of Jace's truck, I gave him a silent nod of approval and he reciprocated in understanding. Maybe, this wasn't such a bad thing at all.

Thanks for reading! I hope you are all enjoying the story so far. I know that I've only gotten through one day, but it's because I'm doing all these different points of view and I kind of like it. It means the story will be longer in the long run. Anyways, so we'll have Will and Tessa's first date next chapter so look forward to that!

Let me know what you think and leave a review! :)
