Austin's little sister(Austin and ally)

Surprise!!!

It was a peaceful Saturday afternoon at the A&A music factory and what looks like a new student walks in looking very confused.
Mackenzie's POV
Ally noticed me and walks over to talk to me.
" hello, can I help you?"said Ally. "I am looking for Austin moon"I say
"Ok, I will go get him for you"
(Austin and ally talking)
"Hey, Austin someone is here to see you" says Ally
"Ok,who is it?"
"Don't have a name but it is a little girl"
"Wonder what she wants to talk to me about"
"If you wanna know go talk to her"
(Ally pushes Austin over to her)
( now with Austin and Mackenzie)
"Hey,you wanted to talk to me" says Austin
"Yeah, I know you won't believe this but..."
"But what?"
"I am your little sister"
" I am an only child"
" it is true ask your parents"
"Ok I will call them right now"
(Calling his parents on speaker phone)
Austin"mum, dad is it true that I have a little sister"
"Yes, honey it is true" his mum says
"How could you keep this from me?"says a confused and hurt Austin
"We are very sorry we kept this from you son"said a sorry dad
"I can't believe this"
(Austin hangs up)
"I told you so" I said
"I have a little sister this is great, you have to come and meet my friends"
"Ok"
