Khairu's deathbed confession is the episode's real payoff: after episodes of implication, we now have a named, direct admission that Malik ordered Shah Nawaz Khan's death. That part is no longer ambiguous.
What's still deliberately unclear is Mohammad Yaar himself. He frames his visit as a reluctant act of conscience — "I feel more sympathy for you than anything" — but he also tells Ali Khan, unprompted, that Aeliya already knows he's here meeting with the Khans. That's not a small detail. A man supposedly protecting Ali Khan's family has no obvious reason to be in contact with Aeliya at all, let alone comfortable admitting it. Combined with his theatrical, riddle-heavy way of delivering information — dragging out "the truth" for several minutes before saying anything concrete — the episode is building him as someone extracting value from both sides of this conflict, not a neutral truth-teller. Dadi Jaan's line to Ali — that he and Miraal may have been fed the same story from opposite directions — reads as the show's clearest hint that Mohammad Yaar, or someone using him, benefits from keeping both households at war rather than resolving anything.
