After returning from the Sacred Island, Frey was stunned to see his counterpart, Prince Aegon Valerion, alive and well.
He had thought he'd killed him ..finished it. Instead, Frey found that Aegon would remain a thorn in his side for longer yet. Their struggle had been written to continue, and no one knew where it would lead.
Cornered and forced to decide, Frey had been a breath away from doing the unthinkable ..killing all those people to bring the prince down .. showing his full readiness to sacrifice them and feed the Blood Path with their souls.
It would have been a point of no return. But Uriel's last-second intervention prevented it.
Clinging to him, binding him with her chains, Uriel carried him into the sky while Snow followed, keeping them away from where Aegon and the others stood.
The prince had managed to draw most of the Empire's main strength to his side .. and to turn them against Frey. In many eyes, Frey was nothing but a blood-thirsty monster.
