RWBY (2013)

S4E3 Of Runaways and Stowaways

Blake sets off for Menagerie aboard a ship, but their journey is interrupted when they come under attack from a Grimm. With Sun’s unexpected help—having secretly trailed her after the fall of Beacon—she manages to defeat the creature. Sun proposes to assist Blake in looking into the White Fang, but she expresses her desire to go home and recuperate instead. Meanwhile, in Patch, Yang receives a bionic arm from Ironwood but struggles with the idea of using it, haunted by her past encounters with Adam.
