"Breach" is the twenty-eighth episode of RWBY and the final episode of Volume 2. It premiered on the Rooster Teeth website on October 30th, 2014.

Summary
Inside Team JNPR's room, Jaune Arc is awakened by a call from Ruby Rose. He tries to answer it, but interference ends the call before Ruby can respond. The next day, Team JNPR is about to leave for their mission, but Jaune is still worried about Team RWBY's well-being. Suddenly, the City of Vale and Beacon Academy both activate their emergency sirens, leading to Jaune changing his team's mission; JNPR boards the Bullhead and flies to the city. Meanwhile, Emerald Sustrai and Mercury Black realize that their plan has started ahead of schedule, and they ask Cinder Fall what they should do.

In the city, Team RWBY is surrounded by waves of Grimm and a fight starts. Together they manage to stand their ground against the Grimm; however, one of Yang Xiao Long's maneuvers causes her to be crushed into the ground, while Ruby finds herself against a King Taijitu. Thankfully, Nora Valkyrie arrives at the scene and attacks the snake Grimm as the rest of Team JNPR arrives and charges at the enemy. Together they continue to defeat tons of Grimm, but Jaune finds himself in front of a fairly tall Ursa. Although initially intimidated, Jaune recalls his previous victory against the Ursa Major and delivers several slashes from Crocea Mors. The Ursa slowly falls to its death, as Pyrrha Nikos watches proudly. Sun Wukong and Neptune Vasilias comically introduce themselves as junior detectives, just before James Ironwood's army arrives and saves Ruby through close air support.

Emerald, Mercury, and Cinder arrive at the city, where Cinder orders her two allies to help fend off the Grimm before leaving. From the hole where the Grimm are entering the city, an Atlesian Paladin-290 emerges with Zwei on top, as the courageous Corgi attacks one of the Grimm. The group is then reinforced by Team CFVY and the Beacon staff - Bartholomew Oobleck, Glynda Goodwitch, and Peter Port - who work together to wipe out the remaining Grimm and capture Roman Torchwick. Professor Goodwitch seals the hole, preventing more Grimm from entering the city.

Professor Ozpin meets with the Council of Vale via video screen - the Council, worried about recent events, reprimands Ozpin for his leadership skills and appoints General Ironwood as head of security for the upcoming Vytal Festival tournament. Later, Team RWBY is seen sitting down and watching the sunset. Weiss asks what they are going to do now, and the group decides to go to bed. Meanwhile, General Ironwood, who has received custody of Roman, attempts to interrogate him, albeit to no avail.

Later, Cinder, Emerald, and Mercury stand on a roof overlooking Vale while Cinder remarks that the day was a success. Mercury notes that a lot of Faunus were left in the tunnels, and wonders if the White Fang will listen to Cinder and her team now. A voice answers that while the White Fang won't listen to Cinder, they will listen to him. The voice is revealed to be Adam Taurus as he walks up to join the group on the roof.

In a post-credits scene, Yang heads to the Beacon courtyard at night and meets Raven Branwen, who removes her mask, revealing that she looks just like Yang with a darker color palette. Raven then tells Yang that they have a lot to talk about, as the screen cuts to black, ending the volume.
