I'm posting the next chap at midnight

Planning a wedding wasn't that hard. Hosting a wedding in secret was. Maryse and Robert knew nothing about it. Absolutely nothing. But, it seemed that luck was on our side. Maryse had gotten a call from the Clave that they needed to go back to Idris for a week, which means we don't have to tell them about the wedding. Maryse announced it in the morning and left hurriedly to pack their bags. Everyone sent them on their journey and gave them farewells. The moment they were gone, Isabelle dragged Simon to the nearby church to organize the place for our wedding. Isabelle had become our unofficial wedding planner. I was worried. Very worried. Worried that it may all go wrong, worried that there might be an attack. I sighed as we went back to the Institute and got my phone out to call Alice. My dress would have to be made by me. When I told her what I planned to do. She agreed and told me she'll arrive in New York in 25 minutes. I drew the dress out first. Golden yellow with a little lace and sequins for the top. The same golden yellow with swirls on the satin material for the bottom and sequins to the waistband of the dress. It looked great to me. Alice arrived soon enough, knocking on the door loudly. I jumped out if the open window and landed right before Alice with only the gate separating us. Her jaw fell open as I let her in. However, it was not the Institute but how I looked. "Trini! Oh my gods you look so different!" She gasped. I shrugged. "Lets go in." I pointed to my room and me both jumped onto the window ledge and into my room. I led her to my design and showed her the sketch. She used a number 2 pencil and lightly sketched a light yellow layer underneath the layers of satin. It was perfect in case of an attack. Just push off the satin and it becomes a bulletproof cape. Perfect! I picked up a great length of cloth I bought secretly and handed it to her. "How about this as the fabric?" I told her. She beamed.

The big yellow wedding will be posted tomorrow, earliest

This actually came as a spark of imagination. There'll be a fight at the end of the wedding and it turns out that Trini McLean/Clearwater was prepared.

Wedding chapter will come earlier than I thought.

We stepped into the kitchen, hand in hand, where everyone was in the kitchen. I glanced at Seth and raised an eyebrow. He gave me a nod and I went off to speak with Isabelle, Maia, Clary and Jocelyn. "My room, second floor, five minutes. Meet me there." I whispered into each of their ears and they gave me a puzzled look and agreed. Seth however, had asked everyone but Magnus to meet him t the library. I sighed and walked over to him. "Magnus," I began. I noticed everyone leaned forwards to hear my new. I sighed. "You know what? I think I'll just show you." I put a hand on his forehead and showed him standing on the altar pronouncing Seth and I husband and wife while wearing sparkly gold eyeshadow. I heard his intake of breath and pulled my hand away. He started nodding immediately. "Of course, of course!" He cried and swept me into a huge hug. "Of course! It's a huge honor to ma-" I covered his mouth with my hand and shook my head warningly at him. He nodded slowly and I put down my hand and strode out of the kitchen and into my room. Five minutes later, Izzy, Maia, Clary and Jocelyn appeared at my door. I dragged them onto my bed and started immediately. "Listen. We've got ten minutes before Maryse and Robert come back. Seth is giving the rest the same prep talk. You 4 are attending my wedding in two days. You're gonna be my bridesmaids." Isabelle squealed and I winced. "My maid of honor is an old time friend called Alice Cullen. You guys will be wearing this." I held up the purple dress. "Izzy, you can do the make-up on everyone except for Magnus. He's going to have sparkly gold eyeshadow. Alice is shopping for your dresses right now. I don't have a mother to approve of my dress but I could at least ask you guys." I held up the picture of my dress and izzy squealed again. "It's beautiful." Jocelyn smiled warmly at me. 

"I need you guys to be up and about at about nine. And nobody gets hurt or in a fight, understand?" They all nodded. "Somehow, I think I should be telling Jace instead. Oh well, lets go welcome Maryse and Robert back!"
