More explanation for y'all. Since some of y'all still confused.

Yang had just finished her shift and jumped down the perch to wake up Weiss since she volunteered to go after her. It was just a standard routine mission that every team at Beacon has to do. Previous team reports indicate that this area was supposedly clear of any Grimm but scout reports indicate otherwise. Small time hunters spotted a beowolves gathering at some location near their mission vicinity. All they were supposed to do is clear out as much Grimm as they could in the area and leave. Without entering the nucleus of where the Grimm are gathering. This was meant for older teams.

Yang gave Weiss a quick nudge to the shoulder, "Hey, Weiss, it's your turn. I'm pumped to get sleeping." Weiss' eyes opened as she saw the blonde girl and said no words but got out of her bedroll, heading straight up to the perch, ignoring Yang. Yang got into her own bedroll and slept peacefully away.

"Yang, Yang, wake up!" Weiss screamed quietly into Yang's ears as she shook her bedroll, "Your sister's missing!" Yang's eyes widened as she looked around. Blake was already looking around their campsite for any telltale signs where Ruby could have gone. On the other hand, Weiss was visibly shaken that her partner was gone. But Yang took it worse. She dearly loves her sister and losing her would basically lose a part of her own identity.

Disregarding her hair, she strapped on Ember Celica onto her wrists. She contacted Beacon as soon as she finished wearing her weapons with a distress call.

"We can't split up. It's really dark and separating would be a very bad idea for us," Yang said.

"I agree," Blake added, donning her own weapon. "I did find this.," Blake showed a torn piece of Ruby's cloak, "She could've headed that way."

Weiss nodded and volunteered to lead their small search party. She had insisted that Yang always keep a signal between Beacon and themselves so that whoever was responding to their distress call could always know where they were at all times. Yang gave her thumbs up and the three proceeded towards where they thought Ruby could have gone.

It had been exactly eight hours since they had begun their search but to no luck, Ruby was still nowhere in sight. Yang's face was clearly showing signs of worry and heavy stress. Blake took her hand and kept it with her to somehow relieve her girlfriend from her worries, "Don't worry, Yang. I'm sure we'll find your sister."

It had been eight hours but within those eight hours, the remainder of team RWBY had been in contact with officials from Beacon. It was not a huge search party looking for one girl who absolutely loved to bounce around the forest.

However, they were at fault. All of them including the Weiss, Blake, and Yang weren't looking in the right area. They had circled the entire perimeter but to no avail, no Ruby either. As a stroke of "genius or luck", Weiss suggested they broaden their search. She was getting frustrated too. Ruby was her partner and her best friend. Someone who she knew she could trust and someone she could love. But Weiss didn't know why Ruby kept resisting her advances saying that she was already taken, that she did the deed whenever she came back from training with team JNPR or whenever Weiss tried to tell her directly that she loved Ruby Rose. Blake knew of this but also knew that Ruby was delirious.

It was either an act of cowardice or an act of neglect. Blake knew everything that Ruby was experiencing but she kept everything hidden from her girlfriend and worse of all, Ruby's very own sister. However, one day Yang found out that Ruby was having delusional dreams when she screamed about murder in her sleep and killing her. Yang confronted Blake since Blake was the closest person to Ruby and they got into a huge argument that led to a broken limb. Ruby was there.

Two more hours lapsed and Yang finally saw her sister. Her pulse was essentially nonexistent and her legs were gone, eaten to a bloody pulp. But somehow, she still had some aura left in her that made her breathe even though in small breaths. Zwei was dead and worse of all, Ruby was unrecognizable. Yang screamed in agony and Weiss cried silently as she tried to suck it up like the princess that she was. Blake blamed herself.

Blake was never there for Ruby. She just listened to her troubles and did nothing about it. Blake thought of herself as a horrible person for neglecting to do something about Ruby.

Yang's screamed turned into anger as she faced Weiss, "You! It's all your fault! How could you let Ruby slip away?!"

Weiss was speechless. She knew she was at fault. She had fallen asleep during her two-hour watch shift. She just woke up and Ruby was already gone. The next thing she felt was the full force punch of the blonde girl to her face. Luckily, her aura had absorbed all the damage and she stood still.

After punching the heiress, she turned her attention back to Ruby and called for an immediate medevac. An airship arrived within five minutes and Ruby was taken away to the nearest hospital.
