Ruby, Blake and Pyrrha busted into team JNPR's room. Jaun shouted, "Hey, what's going on?" Ruby immediately pointed her gun-scythe at Jaune's face. "Don't move, killer!" Ruby shouted, as Blake pulled up a loose floorboard, revealing the killer's costume inside the floor. Jaune looked up at Ruby, appalled. "Ruby, you don't honestly think that I…" Ruby kept a straight face. Jaune was the killer. He had to be. Pyrrha then walked into the room, keeping her head down, refusing to look at Jaune.
Jaune was brought in for questioning, and the costume was taken as evidence. Jaune had claimed never seeing the costume in his room, and he had no idea where it came from.
Pyrrha on the other hand, claimed she saw Jaune hide it in the floorboard while she was trying to sleep in the nearby bed.
Ruby and Blake watched General Ironwood interrogate Jaune yet again through the one-way glass window at the police station. Ruby couldn't believe Jaune would do this. It just didn't seem like it could have been him. Blake looked down at Ruby, who was watching Jaune carefully as he answered the general's questions, almost every one of them responding with "I don't know." Blake then put her hand on Ruby's shoulder, "You don't think it's him, do you?" Ruby stood, unmoving, before shrugging Blake's hand off. After the general left the room, another interview wasted with no new information, Ruby spoke, "I don't know what to think anymore." Blake wanted to reassure her, but found no encouraging words to say. Ruby honestly thought he was innocent, but at the same time, she wanted vengeance for her sister and Weiss.
After Ruby finally got home again, she started looking through some of Weiss's and Yang's stuff. She couldn't help but feel as though something was missing. Eventually, Ruby stumbled upon a small book. She opened it, and found it was Weiss's diary. She skimmed over some stuff, trying to see if there was any new evidence. She eventually found a part of the book where Jaune asked her out again, and she wrote about how annoyed she was. Ruby chuckled a little bit, and suddenly realized something. Didn't Jaune love Weiss? Even though she broke his heart after she started going out with Neptune, why would he killer her? And why Velvet, the one he tried to protect for so long? And then Ruby, his first friend he made at this school. She had to talk to Pyrrha, something about Jaune doing all this just didn't seem right.
Ruby dashed through the hallway and down to team JNPR's room. No one was home, so she called Pyrrha on her scroll, asking her where she went. Pyrrha didn't answer. Ruby was about to call again, but then it hit her.
The costume was found in JNPR's room, and Pyrrha knew where it was hidden.
Weiss was asked out by Jaune.
Ruby was Jaune's good friend.
Jaune stood up for Velvet when she needed him.
Pyrrha had a crush on Jaune.
Ruby looked around team JNPR's room, and opened Pyrrha's nightstand drawer. She found nothing but a small box, which had a small hole in it. It was a box that was able to hold a knife. Ruby knew it. She had to find Pyrrha, but suddenly, she felt a hard blow to the back of her head, followed by the sound of shattering glass. She fell down to the ground, and saw Pyrrha standing over her, holding the broken remains of team JNPR's table lamp. Ruby fell unconscious, as Pyrrha stood over her.
