Yang had woken up early and noticed Ruby wasn't up either. Come to think of it, she hasn't seen Ruby at all. Not since Yang and her talked about Weiss and Blake the day before. A breath hitched in her throat at the thought of her Faunus friend. She shook the thought out of her mind and approached Ruby's room, knocking softly. When there was no answer, she tried the knob. Unlocked, good. She went in to see that Ruby wasn't in bed. Ruby must have been downstairs with their father.
She rubbed the back of her head and trudged down the steps to the living room. Ruby wasn't in here, either. No problem, must be in the kitchen. She pushed away the curtain separating the living room from the kitchen and saw her father.
"Hey, dad." She didn't see her hyper little sister. "Where's Ruby?"
Taiyang slipped a slip of paper towards her, and she saw the sadness in his blue eyes. Yang picked the letter up cautiously, as if it were going to combust at the slightest incorrect movement. She read over it, how Ruby was going to find something; though she didn't specify what. How she didn't want to worry them, but she had to do something to right what she felt she did wrong. Yang repeatedly shook her head at the letter.
"She can't be going. What happened wasn't her fault! I have to go after her."
"Yang, that's not wise." His voice was cool, but slightly shaky.
"Dad, I have to go after her. She's my sister!"
"Yang, you can barely get up in the morning. It's not safe."
"Safe or not, I have to protect my baby sister. I have to protect Ruby!"
"You could get hurt."
"So could she!"
"Yang-"
"Dad, I don't know what I-" She took a breath and continued, "I don't know what I'd do if she ever got hurt and I wasn't there to protect her. I know she's your daughter, but she's my sister. She's a kid, she's seen so much death and so much pain. I can't let her do this alone. Even if it's unsafe, we'll be together."
"You read the letter, she isn't alone. She's with-"
"Yeah, she's with Jaune, Nora, and Ren." She took a deep breath. "But she's not their baby sister, Dad. She's my sister, I have to protect her."
"Yang, you only have one arm. You're an amputee, what makes you think fighting will save either of you? What if you lose both arms, Yang? Please, think this through."
"I may be an amputee, but I'd sooner lose both my arms than let anything happen to her! Dad, I have to go. I have to find her. I have to find her and I have to protect her. I couldn't protect Penny or Pyrrha or even Blake. I have an obligation to Ruby. Not just an obligation, I want to protect her. I want my little sister with me. Even if I don't make it in the end, I have to know she will. Or that I at least ensured she'll live longer than I do!"
Taiyang sighed, knowing he wouldn't be able to talk Yang out of this. "Fine, Yang. But be careful. Please. I don't want to lose either, or worse- both, of you."
Yang hugged him, "I'll be careful. I will do anything and everything in my power to protect Ruby. I promise."
"I know you will, Yang." He whispered softly, tightening his grip around the blonde teenager.
She pulled away from their hug, and looked at him again before rushing upstairs. She grabbed a survival-purpose backpack, and threw clothes in haphazardly. She looked at the metal bracer she wore when she was in battle. She didn't know if she was strong enough to wear it again, and furthermore; didn't know if she'd be able to wear it at all. She packed it anyways, as well as a sword she had gotten practicing at Signal before she found the bracer. The sword would be handy if she were to get in combat and wasn't able to wear aforementioned bracer.
She got to the bathroom and packed her pain meds that the doctor had given her for her arm, as well as bandages and antibiotics. She also packed a brush for her sometimes unruly blonde mane. After raiding the house for packing, she finally got to the front door. Taiyang stood and said his goodbyes. She opened the door, then looked back at him.
"I will bring Ruby home."
