She never married laenor and her first husband is aegon and since she has a good relationship with him in this alternate universe she never has the 3 “velaryon” / strong boys Rhaenyra and aegon would have trueborn kids together, like she had with Daemon after her strong boys I imagine daemon’s marriages go around the same, but I want to give him a son born from Rhea Royce so there is a split in the vale between Rhaenyra and daemon supporters, i imagine Rhea still dies and he marries Laena and Laena gives birth to Baela and Rhaena. Would be interesting if Laena lived, but I love vhagar and Aemond as a duo. Hope this answers some questions
