Well this is my entry for Kilala97s contest.
 
I love Golden Delicious and Api, but there is so little about their dynamic, so I took what I know about them and mixed it with a little personal experience. I dont have brothers, and my sister and I dont live together (daughter of my father) and do not have a good relationship, but I have cousins.  
Once we were on a vacation trip to the beach with my cousins and my uncle, there I met for the first time the girlfriend of one of my cousins, Anna. She was super fun and I loved playing with her.  
They had a big fight, and I listened most of it, cause my room was adjacent to theirs.  
I was sooo mad with my cousin, I yelled at him even.  
So if I was so worked up to hear a girl (that Id met 3 days ago) I can imagine how pissed and angry I would have been if I knew Anna for years.
 
So here is my idea.
 

 
Api: DEL!!!
 
Golden sees Api running towards him, jumping on the table near him. He puts his suitcase aside.
 
 
Del: Hello little cousin Wanted to see me and be the first to welcome me back?  
A: No well yes, but more important What did you do?  
Del: Hu? Im not following  
A: You know she sees him with anger  
Del: I do not Came on Api, What are you talking about?
 
She starts pocking with her hoof, his cousins side.
 
A: she puckered her eyes and watched you her cousins eyes you made Candy cry what did you do?  
Del: I what? I would never make her cry  
A: You did That is what Sugar told me  
Del: Did she tell you why she thinks it was me?  
A: Yeah Sugar said she heard Candy sobbing in her room saying stuff like I am so happy for you Del blah, blah, blah.
 
Golden Delicious looked in the little fillys eyes, knowing she wasnt lying.
 
Del: Not sure what I did, but I m gonna talk to Ceecee and ask her  
A: You sure must!
 
He goes to the door, and just after he opens it, Api says.
 
A: Candy is the best babysitter, big sis and friend Dont you ever make her cry again please?  
Del: I promise just about to go out when Api  
A: ?  
Del: Get down the table, you will hurt yourself
 
Api sticks her tongue out and jumps off the table, crushing the suitcase with her muzzle.
