, maneuvering for the Iron Throne continues despite the fact that King Viserys (Paddy Considine) has named Princess Rhaenyra (Milly Alcock) his successor -- and that council pledged to honor the decision when the day comes for her to wear the crown. One of those people still positioning for the seat of power is Lord Corlys Velaryon, aka the Sea Snake, played by Steve Toussaint. The actor tells ET that his character is full of pride and resentment and still reeling from what happened to his wife, Princess Rhaenys Targaryen (Eve Best), many years prior. “He doesn’t hide the fact that it irks him that his wife is not on the throne,” Toussaint says, not hiding the fact that he thinks Rhaenys is a far more qualified ruler than her cousin, Viserys.
