When Aemma died, Viserys was devastated, truly devastated, he loved her for certain, though he never fully acknowledged the fact that it was his fault she died. But, as a King, he required more than one heir, and Rhaenyra, a girl of seven, would simply not do. What if something happened to her? He'd have no one else to be his heir.

And he certainly could not let his brother, Daemon, sit the Throne after his death. But, he could let Daemon's grandchildren sit the Throne. Which was why Viserys married Daemon's daughter he sired with Rhea Royce. Viserys' neice was a good mother to Rhaenyra, and thankfully, Rhaenyra adored her new stepmother despite her mothers death.

Viserys had wanted a family dinner, to celebrate the fact that his marriage was going well. But during the whole dinner, Viserys could feel Daemon's eyes on him. There was an anger, a hate, in his brothers eyes. Obviously Daemon was infuriated by the fact that Viserys was married to his daughter.

Viserys swallowed thickly and offered a small smile to his niece-wife and his daughter as the two discussed something that Rhaenyra had done that day, brushing off his brothers hate. Viserys stood up, raising his cup as he spoke.

"I'd like to make a toast. To my wife's health and fertility, and hopes for a healthy pregnancy."

There was no true confirmation that his niece-wife was pregnant yet, but the maesters have pointed out signs of early pregnancy and Viserys could only hope.
