So, I understand that the last chapter left some confused. Here's the explanation.
Yang woke up in her bed, safe and sound. She felt around her for her scroll. Realizing her bed was soaked and empty, she got out, and felt her way to the bathroom, and flipped on the light. She looked around and saw her scroll. She picked it up, sat on the counter, and started scrolling through her contacts. Ruby, Blake, Yang, Pyrrha, Velvet, and on and on and on, until she found your name. "Hey (Y/N)! It's Yang...from high school, I know we haven't talked for years. How are you doing?" Yang stared at her scroll for a half hour, until *ping*
"Hey Yang, sorry it took me so long, I'm doing fine, I'm on tour in Atlas though. I remember you talking about going to Beacon when we were in school together, how'd that dream go?"
"It's gone great! I'm in my first year, and my little sister even skipped up and is in the same grade as me!"
"I'm sorry Yang, I can only answer one more question, I have a show to do"
"You're famous?"
"Yes Yang, I am famous. I'll be in Vale in a couple days, you and your friends can come to my house"
"That's not necessary"
"I insist"
"Okay, I'll ask my headmaster"
"I'll see ya Yang"
"See ya (Y/N)" Yang typed before shutting off her scroll and laying in bed. Five minutes later, and Ruby's alarm began to ring. Yang shot up, got dressed, and ran to class. Classes went off with out a hitch. After the last class Yang ran to Ozpin's office. While she was waiting Yang decided to ask you a question. "Hey (Y/N), how many people can come?" You got back almost instantly
"You plus seven"
"Okay, thanks" Yang walked into Professor Ozpin's room and sat across from him. "Professor, I was wondering if me and a team of my choice could visit a friends house?"
"What's their name?"
"His name is (Y/N) (L/N)" as soon as Yang said your name Glynda burst through the door.
"Ohh my Oum, (Y/N) (L/N), he's my favorite!"
"Umm, Ms. Goodwitch?" Yang asks as Goodwitch starts jumping up and down.
"Ah, excuse my behavior"
"So, Ozpin, can we go?" Yang asks
"No Yang, you guys can't go" Ozpin says making Glynda and Yang's jaws drop
