Yang watched as her father stepped out of Ozpin's tower, his head down. She ran to him, and he looked up. His eyes looked just like they did the day they found out what happened to Summer.
"What happened?" Yang asked. He looked at her, opened his mouth to say something, then closed it. He then looked at her for a long time before speaking, "This…" He pulled out a handgun, holding the grip between two fingers. Yang's stomach dropped when she saw what was on the gun; the barrel had fresh blood spattered all over it. "Did you…?" Her voice trailed off, and she looked away.
"No," he told her. "She was mentally disturbed, Yang. She… Did this to herself." Yang knew what he was trying to say, and tears formed in her eyes. "She's… She's gone?" Yang's voice cracked.
"Yeah…" He whispered, bringing her into a hug. He tucked her head under his chin, and she sobbed into his chest.
That was three years ago for Yang. But unlike the first time she thought Ruby was dead, she got used to her little sister not being around, and actually graduated from Beacon. It hadn't been easy, especially since Ozpin transferred her to JNPR, and Blake to another team. It was probably for the best. Blake wasn't the same around Yang after Perseus took off the mask, she saw Ruby as another Adam and didn't really trust anyone afterwards.
Yang could at least rest easy, knowing that Weiss actually went to prison for what she did. The blonde remembered the last conversation she had with Weiss after they found her cowering in the library.
"Why?" She asked as she escorted Weiss to Ozpin, her eyes still stung from the tears, but she was too angry to notice. Weiss didn't answer, and instead just stared at her feet. "I want to know why…" Yang said.
"Why does it matter?" Weiss asked. "She's alive, so why does this matter?"
"Because…" Yang began, "Because my sister shot herself because of you."
Weiss looked up at Yang, "Did she—?"
"Yeah." Yang cut her off. "So tell me why you did this."
"Because I was hoping something like this would happen," Weiss was quite obviously bluffing. "And I want you to know that she deserved every fucking second of this, all of it!" Weiss whispered the last part, and Yang decked her, letting her fall to her knees. Weiss looked up at Yang, "Whose fault is it that you didn't believe her?" She asked. Yang kicked her in the stomach. Yang then leaped on top of her and began to repeatedly hit the heiress in the face until Blake appeared and pulled her off. "You can't kill her," the faunas said. "I know she deserves it, but you can't."
Yang made eye contact with her partner and stormed off. That was probably the last time Yang actually had a conversation with her.
Now, Yang was a huntress, just like Ruby always wanted to be. She still wore Ruby's cloak in respect for the fallen girl.
Soon after everything that happened, Yang learned of Ruby and Jaune's relationship. She didn't like the fact that Jaune was using Ruby's mental instability to his advantage, but there was nothing she could do at this point. But Jaune never fully recovered like Yang did, he refused to believe that Ruby was actually dead, and disappeared looking for her. Yang didn't know if this was because he found something, or if he died at the hands of the Grimm. In fact, she didn't know if he was even really dead.
