Daemon’s time in Harrenhal has provided a strange subplot for House of the Dragon Season 2. While Rhaenyra and Aegon have been planning all-out battles and secret espionage, he’s been doing some home repairs and raising an army by engaging in some mild-to-moderate war crimes. But all throughout, his time at Harrenhal has been interrupted — or perhaps controlled — by visions fueled by a local heart tree and the mysterious healer Alys Rivers.
