It's in the middle of the night when Clary and Jace are up on the shimmering mountain. It's a cold night, but Clary and Jace really didn't care.
Back at the Institute, here stands Kila and Jason (They're new to the Institute) Kila sat down on the step to outside and thought "When in the world are Clary and Jace going to be back." Jason came out and set on the step with her and said "What's wrong? You've been here for an hour. What's on your mind?" Kila said "Nothing, it's just that I haven't been back to see my family in 2 years."
"Here at the training room, Kila, this is where you get all your weapons and everything." Jason said. Kila said "Oh really? Let's go you fight me, then. Jason said okay, let's fight" He picked up a sword and she picked up a little pandemonium blade.
Author Ethan here, and sorry If the first part is short, I'll be updating again, sometime this week. SPOILER Alert, Jace and Clary are together, and I might make this into a lemon
