Rhaenyra is gonna order baby Maelor to be brought to her
Thats what’s gonna cause Helaena and Maelor to kill themselves. Rhaenyra will wanna see if it’s Aegons son and Helaena is going to be terrified of having her baby torn from her or hurt or killed and thats when Helaena jumps with Maelor. That way;
It’s Rhaenyra’s fault KINDA but not really, there’s plausible deniability they can say ‘the maesters we’re misogynistic and stretched the truth when they blamed Rhaenyra’
It’ll play into their favorite trope of ‘hey look at Alicent’s karma’ (bc the queen who never physically harmed you once yet demanding the princess and heir and favorite daughter bring you their son is the same as demanding a hostage bring your baby up to a woman who actively wants to kill your brothers/husband and killed your grandfather)
