Broome Tried to Flip Daemon Against Rhaenyra

Broome did not simply arrive at Harrenhal to assess Daemon's loyalty on Rhaenyra's behalf. He arrived to subvert it. The theory holds that Broome offered to transfer his own allegiance to Daemon and back a rival claim to the throne, exploiting the same ambiguity about Daemon's motives that had been building since his arrival in the Riverlands. Broome's pitch was not spontaneous flattery; it was a calculated attempt to accelerate a fracture in the Black cause that he believed was already there.

What makes the pitch viable as leverage is that Daemon gave it nowhere to be wrong. Daemon has waged this entire campaign as though the war were his own property, raising armies in his name, setting the strategic tempo without consulting Rhaenyra, treating the Riverlords as a personal instrument rather than her resource. Broome did not need to invent a separable Daemon. He only needed to notice one. If Broome surfaces what he knows, the defense Daemon would have to mount, that he heard the offer and refused it, runs directly into a record of behavior that makes refusal look like patience rather than loyalty.

The retreat is the detail that matters. Broome did not leave Harrenhal. He dissolved into the Riverman army, which means his betrayal is unfinished. Daemon called him a turncloak in private and then said nothing more: not to Rhaenyra, not to any lord, not to a guard. That silence is the operative fact. Broome remains inside the Riverlord host with knowledge that Daemon sat with the offer long enough to refuse it rather than immediately report it, and that knowledge is leverage.

Simon Strong's warning raven to Rhaenyra suggests the Harrenhal meeting produced visible evidence of disloyalty that an outside observer could read without knowing exactly what passed between the two men. Strong reported what he saw. He did not report Broome's arrest or removal. If Daemon had neutralized Broome as a threat, Strong would have had nothing alarming to send. The raven exists because the threat was not neutralized. Broome is still present, still armed, still embedded in the host Daemon just handed to Rhaenyra.

The sharpest implication of this theory is that Broome will attempt to use Daemon's silence against him at a moment of maximum pressure, either by approaching Daemon again when the war turns, or by surfacing what he knows to a third party who wants Daemon discredited. Rhaenyra arriving at Harrenhal without ever learning what Broome proposed is not a closed chapter. It is the condition under which Broome operates going forward. And the condition is more dangerous than the original theory recognized: Broome does not need Daemon to be a traitor. He only needs Daemon to look like one, and Daemon has done much of that work himself.
