They cut Ormunds wife and children. Likely so Gwayne can fill Garmund Hightowers (Ormunds son) role as Rhaenas husband and with ormunds wife and children they've cut my favourite irony.

The Greens waged a catastrophic civil war to ensure a woman (Rhaenyra) could not wield absolute power. Yet, immediately following the war, the new Lord Hightower (Lyonel, Ormunds oldest son) marries his (step)mother, Lady Samantha Tarly, and she becomes the undisputed ruler of House Hightower during Lyonel’s regency, siring 6 bastards together living openly in 'sin' for thirteenth years before seating another high septon that 'conveniently' knows a legal loophole to marry them.

While Targ brother-sister incest was protected by the Doctrine of Exceptionalism (theyre not doing it for no fucking reason) stepmother-stepson incest was completely condemned by the Faith of the Seven as a cardinal sin. The Hightowers end up committing a form of incest that horrified Westeros even more than the Targ pairings, divorcing them from the idea of being holier-than-thou. When personal desire arises, the "pious" break social taboos and exercise power over others just like the Targaryens do.
