In season 2, episode 10 of Andor, Luthen Rael meets with his agent within the ISB, Lonni Jung. Jung tips him off that the ISB are onto Luthen, and also tells him about the plans for the Death Star.
Luthen then
kills Jung with the blaster pistol he brought to the meeting, right there on the park bench.
My question is, why?
Is it punishment for withholding his access to Dedra's files from Luthen? Out of fear that Jung would be captured and reveal the location of Yavin Base? (Why, then, tell him where the base is?) It seems like a "blown" Jung is still more valuable than a dead one, and there's also the ethical issue of what Luthen owes Jung.
