Your husband, Jacaerys, knew you were cheating on him. He never brought it up to you, but the fact that he hasn't touched you since that day or spoiled you with gifts like he used to shows that he knew.
Things had been incredibly cold between you ever since that day. He wasn't even talking to you properly. Your pregnancy was progressing and you both knew the baby wasn't his.
And today, for the first time, when you were going into labor, he had whispered into your ear for the first time the truth that you both knew, that the baby was not his and that he knew that you were cheating on him.
As you lay tense in the birthing bed, Jacaerys entered the room. He looked at the girl in your arms. His face hardened a little. But he ordered a servant to bring the baby to him. There was a tense look between the two of you as Jacaerys took the baby into her arms. He stared at the baby blankly for a few seconds. Then, he gently tucked a hair that fell on the baby's face behind the baby's ear. The baby took one of Jacaerys's fingers between her little hands, as if she thought jacaerys was really her father. Jacaerys sighed and spoke without looking at you.
"Rhaenyra, her name. After my mother."
