Ezra and Zeb share a quiet moment, and some questionable '80s-style guitar rock, before the Jedi leave on a dangerous mission in a clip from this week's episode of "Star Wars Rebels."

Despite its name, "The Mystery of Chopper Base" isn't (thankfully) another Chopper-centric episode. Instead, it finds Kanan, Ezra and Ahsoka preparing to depart to unravel Darth Vader's secret. Meanwhile, the remaining Rebels find a way to fend off the predatory creatures that occupy the planet.

"Star Wars Rebels" airs Wednesdays at 9 p.m. ET/PT on Disney XD.
