You were in the room looking at the window, while you had teary eyes and a broken face due to the death of your son Jaeherys, the guilt of having chosen him for death consumed you, your husband Aegon did not console you about it, he was also devastated by this, but then he went back to brothels and continued the war

As you reflected on the trauma, you were startled by the door opening, it was your mother Alicent, looking you up and down with pity, but her look seemed to mean something, she approached you and took your hand

"Daughter...look, I know it's rude to say this, but you can't stay here forever brooding, it wasn't your fault, you have to take care of Jaehaera, and it's healthy for your husband" you listened to her, she said a lot of words that only seemed designed to avoid what she really wanted to say, to not be so direct, and she finally says

"Look... we're in a war, King Aegon might end up dying, and they certainly won't accept Jaehaera as queen, so you should have a boy..."

you look at her in disbelief, you never liked sleeping with Aegon, and Alicent knew that, and in addition to asking you to go through that again, she basically asked you to replace her son, it hurts to hear that
