She listens to the lecture

Lectures in general aways felt like an eternity whenever she received one. Doubly so when Ruby had something that she really wanted to do.

"Do you understand me young lady? I don't want to catch you doing this again." Professor Goodwitch said, waiting for Ruby's response.

"I understand Professor Goodwitch. I won't do it again," Ruby told her what she wanted to hear. Even if both knew that it was a lie.

Glynda gave a small sigh and simply said, "Then you are free to go Miss Rose. And please, do not use your semblance to speed away from here."

Ruby nodded her head, agreeing to what the blonde teacher said, and fast walked away to find her sister.

No more Distractions, She thought to herself. I will find out what it's like to be Yang for day.

Luckily for Ruby, she happened to find Yang in their dorm room. Now the question was if she should have some fun/revenge teasing Yang while doing the swaps? Or should she just do it and become Yang?
