(Warning: Spoilers ahead for House of the Dragon.)
Westeros needs dragons. With Rhaenys and Meleys gone, there’s only one big dragon left in the skies with a rider, and the looming threat of Vhagar has brought the steadily amassing armies to a standstill.
The western forces of Houses Lannister and Lefford won’t march for the Greens unless they have a dragon above their heads. Criston Cole (Fabian Frankel) is reluctant to march on Harrenhal because of the threat of Daemon (Matt Smith) and Caraxes. The Blacks can’t spare more than babies, since their riders also happen to be heirs and aren’t expendable. Rhaenyra (Emma D’Arcy) must somehow find more dragonriders to claim the unridden beasts in their lairs on Dragonstone, but her plan doesn’t go the way she’d hoped.
