Warning: This post contains SPOILERS for Andor episodes 1-3!
There are no subtitles in Andor when characters speak in the native Kenari language, but that is part of the show's plan - not a sign that Disney+ is broken. The galaxy far, far away has always had various languages and forms of communication, even though most characters speak in the Basic language, which viewers know as English. However, the Star Wars franchise does not have a set of guidelines for which languages are translated through subtitles and which are not. Andor adds another to the not list through the show's flashbacks on Kenari.
Kenari is the homeworld of Cassian Andor and the main location for Andor's flashbacks in the first three episodes. Viewers get to see a young Cassian and his sister Kerri live among a group of other native children on a planet that was previously devastated by a mining accident. The flashbacks show an eventful day when a Republic cruiser crashes on their planet, leading to the kids devising a plan to investigate the crash site. It proves to be the last time Cassian is on Kenari as a child, as he is adopted by two scavengers who understand the danger he is in after the kids kill one of the officers. Andor's Kenari scenes are quite engrossing, even though the dialogue is left up to viewers to interpret.
The show's creators purposefully made the decision not to include Kenari subtitles in Andor, just like George Lucas did with several alien languages. It puts more of an emphasis on the viewer to decipher what is happening based on the body language and movements of the children, as well as the inflection of their voices and their actions that follow. Giving Andor subtitles would result in the show plainly stating the thoughts and actions of the kids, but removing them from the equation confirms that viewers do not need to know the exact dialogue to understand what is going on. It might even be a way for Andor to heighten the show's realism, as Kenari's language is not commonly spoken. Since the show is the first exposure to Kenari for Star Wars, audiences are left in the same position as the scavengers by not being able to understand a young Cassian.
What We Think The Kenari Subtitles Would've Said
Even without the Kenari subtitles, it is possible to roughly decipher what is happening in Andor's scenes before 5 BBY. They begin with Cassian's sister Kerri calling him "Kassa," revealing that this is his real name. She is there to wake him up and let him know about the Republic cruiser flying above Kenari. The kids then gather together to prepare for their travel to see the crash site, which is where Cassian seemingly tells Kerri to leave him alone and that she cannot come. It appears that their final exchange right before includes Kerri asking when he will come back, with Cassian likely responding that he'll be home later that day.
There is little dialogue spoken as the kids travel to the site of the crash, but Andor's Kenari subtitles could have revealed more about their plan to explore it. The group's leader lays out a strategy that seems to be based around her going first and telling the others to follow once it is safe. Before Andor episode 3, the kids begin screaming once their leader is shot and killed, and they begin talking about how they need to take her body away thereafter. Cassian then appears to threaten to kill the scavengers in what would be the last need of the Kenari subtitles in Andor.
New episodes of Andor release on Wednesdays on Disney+.
