In Andor Season 2 Episode 10, Luthen Rael makes one of his most brutal yet calculated moves, killing his own spy. But why did he do that now, after so many years? Here’s a breakdown.

Why Luthen had to kill Lonni Jung in Andor Season 2 Episode 10
Lonni Jung had been an important asset inside the ISB, feeding Luthen vital intelligence about the Empire’s operations. However, in Episode 10, Lonni uncovered a devastating secret: the Empire’s so-called energy program was a front for the construction of the Death Star. Realizing the urgency, he reached out to Luthen, hoping for protection for him and his family in exchange for this critical information.
But Luthen knew the risks. If Lonni Jung was caught, Imperial interrogators would break him, exposing rebel secrets, operatives, and Luthen himself. The Rebellion was still fragile, and one slip could dismantle everything they had built. In Andor Season 2, to protect the cause, Luthen made the agonizing choice to kill Lonni, ensuring the Empire could never extract information from him.
This wasn’t just about silencing a potential leak — it was about ensuring the Rebellion’s survival. Luthen had spent years building a network of spies, informants, and fighters, all working in secret. If Lonni cracked under torture, it would unravel everything. However, Luthen’s resolve didn’t end with Lonni Jung’s death.
Knowing his own time was running out, he destroyed all traces of his rebel operations before ISB officer Dedra Meero cornered him. When she revealed she knew his true identity, Luthen refused to give the Empire the satisfaction of breaking him. Instead, he took his own life as a final act of defiance.
All in all, Lonni Jung getting killed by Luthen is another tragic entry in the ledger of sacrifices made in the shadows in Andor. For Luthen, keeping the Rebellion alive requires silence, severance, and sometimes, betrayal.
