~~~At Patch~~~
~~~Night time~~~
~~~Summer P.O.V~~~

I was in the house where I was taking care of Yang, while Tai and Qrow out for the groceries. I standing near a window and looks it outside at the window and watch the sky where the star at and it was a clear sky so I thought to bring Yang outside to watch the sky full of the star.

Summer: Hey, sweety. Wanna watch some pretty star?
Yang: *giggles*
Summer: I will take that as a yes.

I pick up Yang walks outside of the house and let Yang watch the star. I was still surprised that, Yang was excited and cheerful and the fireflies came out from the forest and flying around, Yang saw the fireflies and she tries to catch it. I laugh at Yang that she tried to catch a firefly, I look up at the sky again, I saw a shooting star that came across, from the sky.

Summer: Yang, look, it's a shooting star.
Yang: Shiny star!!
Summer: Yes, come on, let's make a wish.

I holding Yang's hands together and close it together, I told Yang to close her eye to make a wish. After she finishes wishing, I ask her what her wish.

Yang: I want a baby sister!! *toddle voice*
Summer: Ok, let's head back inside.
Yang: Ok, mommy!

I start to go back to the house, I saw the shooting star that flew by us, it becomes bigger as it was falling. I quickly take Yang back to the house and hide under the table. After a moment, the ground starts to shake rapidly for a short moment. I came out from the table and I was still holding Yang who was scared of the sudden earthquake, I went out of the house and I was holding Yang close to me.

I went to the crash site when the shooting star should impact, I slowly went over there and saw a person lying in the crater, he was wearing a blue stripe jacket and pants, and a silver hair. I slowly went down to make sure he was alright, I check his pulse, that he was still alive but with the wound on his body, I decided to carry him back to the house, and Yang was holding my hand.

As I went back to the house, I saw Qrow was in front of the house, I call at him to help me out.

Summer: Qrow, I need some help!
Qrow: Summer, where were you?
Summer: I will explain later, help me take this man into the house, he needs some bandage.

Qrow help me carry the man inside the house while I put Yang back in the crib and take the medkit to heal this person.

~~~Later~~~
