They're out pretty soon after quite the fight.

Yang ended up encountering a girl named Blake she and Ruby had met the previous night. And since she was currently unattached, that made them partners. Before they could do much however, they had encountered Ruby and Weiss, who had literally almost dropped out of the sky on them. It had involved an escapade with riding a Nevermore, something Weiss had been firmly against. Jaune, partnered with Pyrrha, had also arrived, having recently shaken a Deathstalker Grimm. Not long after, two more people joined them, a guy named Lie Ren, and Nora.

They quickly went deeper into the forest, before finding an ornate chess board, and several pieces, all in pairs. Assuming these were the relics, they each claimed one, Ruby and Weiss choosing the same one as Yang and Blake, while Jaune and Pyrrha's choice matched Ren and Nora's. Unfortunately, the Nevermore came back around then, and the Deathstalker also found them, leading to the eight booking it towards a more favorable environment to fight these high tier Grimm.

They ultimately settled on a set of ruins, and prepared to make their stand. Jaune ended up leading the group fighting the Deathstalker, Ruby taking charge of dealing with the Nevermore. Yang, familiar with Ruby actually being rather smart, having been on the wrong end of her scheming little mind before in video games, followed her lead without question. During the fight, they proceeded to prove their tactical minds. Jaune's group ultimately killed the Deathstalker by Jaune having Ren distract it, then Pyrrha severed the tip of its tail with her weapon just as it hovered above its body. The stinger fell into its carapace, the weight and hardness puncturing it, leaving cracks and lodging in. Nora immediately followed it up by striking it with her hammer, fatally driving it in fully.

Meanwhile, Ruby's team managed to corner the Nevermore against the face of a cliff, and Ruby had launched herself at it, using Weiss's glyphs to run up said cliff. All the while, she was dragging the Nevermore behind her by the neck with the sharp edge of Crescent Rose. It essentially turned her weapon into a guillotine that beheaded the Nevermore in what could only be described as truly epic style. Once they succeeded, the eight headed for the extraction point, and boarded the airship.

...

"Whoo, that decapitation was nothing short of pure awesome!" Yang cheered as she and Ruby took a private moment in the airship to celebrate their little victory. They were in one of the little side rooms in the vehicle.

"It really was, wasn't it!?" Ruby laughed, pumping her fist. "Ya proud of me, big sis?"

"Oh definitely! And honestly, I'm only a few months older than you, you don't need MY approval!"

"Oi, I still look up to to you, you know!" Ruby stuck out her tongue playfully.
