They dislike and have little trust for the Order after their parents were killed during a Jedi mission that also destroyed their home. Bounty hunter Cad Bane had been fleeing from the Jedi when he shot a transport ship, knocking it off its flight path. A Jedi, possibly Luminara Unduli, was in pursuit. She steered the transport ship away from a heavily populated landing platform, but didn’t seem to realize or care that people also lived in the lower-level apartment block where it ultimately crashed.
The orphaned Martez sisters found no solace in the Jedi after the accident, thought. She simply left them with an assurance that the Force was with them. After that, Rafa and Trace were forced to fend for themselves in Coruscant’s dangerous Level 1313. It’s understandable, then, why the sisters resent the Jedi.
But in the course of their adventures with Ahsoka, Trace and Rafa befriend her despite her past. She hides her identities from them at first, but by the end, they’re loyal to her despite where she came from, and know she left the Order. The trio eventually part ways after a run-in with the Pyke Syndicate and the Mandalorians, with Ahsoka going off to help free Mandalore from Maul.
Trace and Rafa have clearly joined the fight against the newly founded Empire since then, but who are they working for now? Their mysterious employer allegedly wants to use the tactical droid’s data for the greater good, but an ominous ending throws doubt on what the ultimate goal is. More on that below…
The droid traveling with the Martez sisters looks a lot like R7-A7, Ahsoka’s Tano’s navigation droid. You can even see he has the same green dome and purple-red body in “Decommissioned.” So, is this really Ahsoka’s droid? It’s hard to tell.
Afrer all, R7 was destroyed after Ahsoka and Captain Rex crash-landed a battleship in The Clone Wars series finale, but it’s possible Ahsoka rebuilt the droid and gave him into the Martez’s care at some point. As of now, it’s it could be the same droid but it’s not been confirmed.
