Gayle Rankin’s Own Comments
The alys rivers bigger role house of the dragon season 3 expansion has been supported by Gayle Rankin’s own public comments — which have consistently hinted at a role that goes beyond the source text.
Alys Rivers could be older than Harrenhal and Vhagar, says actress Gayle Rankin. TheGWW

It is about fundamentally reconceiving what she is — a presence that has existed in and around Harrenhal for centuries, shaping the fates of everyone who passes through it.
