Star Wars Rebels season 2 returns after a week's hiatus with an episode focused on Chopper, the Rebels Team's droid. Episode 19 is titled The Forgotten Droid, which airs this Wednesday, 16 March at 9.30pm ET/PT on Disney XD.
The official synopsis reads as follows:
When Chopper gets left behind at an Imperial outpost, he forms an unlikely friendship with an Imperial droid, and discovers a base location for the rebels.
In the previous episode, Jedi Master Yoda asks Ezra to go to Malachor for more answers, and Kanan and Ahsoka decide to go look for this place. The upcoming episode will find the Rebels team stopping for fuel supply, where Chopper spots an exact match for his missing, original left leg and goes after it.
The promo opens with Kanan saying, "After we grab the fuel, we have to blast our way out of here fast" and asks Chopper to be ready. He then spots the match for his missing leg and immediately tells Ezra about it.
Ezra says, "Oh yeah! that droid leg looks exactly like yours." Hera points out, "Chopper! We are not here to shop. This mission is important and dangerous. We need you on the Ghost to monitor imperial transmissions. Let us know the moment Empire suspects anything."
After the Rebels leave, Chopper cannot control himself and goes after the droid leg. He is left behind and chased by Stormtroopers, after which an Imperial droid helps him out, and they together discover a base location for the Rebels team.
