No Brakes

No Brakes is the twenty-seventh episode of RWBY, which premiered on the Rooster Teeth website on October 23rd, 2014.

Summary
After being captured by the White Fang, Ruby Rose is kept under Roman Torchwick's custody, who begins interrogating her while taking advantage of her inability to retaliate by sadistically taunting her. However, he is interrupted by the sound of heavy explosions, caused by the other members of Team RWBY and Doctor Bartholomew Oobleck, who arrive in the underground cavern in order to rescue Ruby. Enraged by the infiltration, Roman orders the train to be prepared for an unscheduled departure along with members of the White Fang. Team RWBY gives chase almost immediately.

Team RWBY boards the train's backmost wagon and Ruby finds out that the train contains a large cache of robots, weapons... and a live bomb. Oobleck orders Blake Belladonna to decouple the car as they leave it behind; however, before she can, the wagon separates itself and detonates. Oobleck later discovers that all of the cars have bombs in them and he realizes that Roman's plan is to create holes in the tunnels that will allow the Grimm to access and destroy Vale. Oobleck decides they have to split up: He, Ruby, and Zwei take the high road to stop the train, while the others take the low road and deal with any additional bombs.

Weiss Schnee, Blake, and Yang Xiao Long enter the train, but instead of bombs, they are met with a series of opponents, beginning with Neopolitan. Yang stays behind to fight her and buy her teammates time, but is overwhelmed by Neo's speed and dexterity and defeated without landing a single blow following an extended battle. Blake and Weiss continue, but a White Fang Lieutenant wielding a chainsaw confronts them. Weiss stays behind and fights him, while Blake proceeds alone. She is greeted by Roman, and swiftly defeats him after using her Semblance along with Dust she acquired from Weiss to create elemental illusions of herself. Roman attempts to convince her to join him, taunting her with her past, but she simply knocks him out. Weiss is knocked into the room by the Lieutenant, and is forced to flee with her teammate. Meanwhile, Neopolitan is about to execute Yang, but a mysterious woman in red teleports in and silently challenges her, causing Neopolitan to flee immediately. The woman leaves just as Yang recovers, and Yang gets a brief glimpse of her rescuer before she disappears into a red portal.

Ruby and Oobleck are seen successfully taking out a Paladin. Oobleck then orders Ruby to go and rejoin her team, and although she initially refuses, he manages to persuade her. Ruby then allows Zwei to join Oobleck. Yang, Weiss, and Blake emerge from within the train and regroup with Ruby, where the group is able to see that the train is about to crash into the final barrier leading to Vale. Weiss shields them with an ice spell, allowing them to survive as the train crashes into Vale. Grimm emerge from the wreck and begin laying waste to the city.

Trivia

 * The handle side of Roman's Melodic Cudgel is revealed to be a grapple hook.

Oobleck's weapon form is revealed to be a rocket launcher/flamethrower hybrid (the fire could also just be fire dust)

At 5:40 one of the White Fang members does the Wilhelm scream as he falls off the train

On the train Dr Oobleck orders Blake to "decouple the caboose" as it will "kill them all." This being a reference to the Red vs. Blue character Caboose, who is known for his constant team-killing and is also voiced by Joel Heyman.

The scene where Yang and Neo square off against one another is reminiscent of two iconic Dragonball Z battles, Goku vs Frieza and Cell vs Gohan.

This episode marks the first battle that Yang has lost.

This episode also marks the first battle Blake has fought by herself.

This episode also marks the first time Team RWBY has fought separately.The title of the chapter, "No Brakes" is very likely a reference to a catchphrase of Ray Narvaez Jr., "The Fuck Train has no brakes!"
